ld combines a number of object and archive files, relocates their data and ties up symbol references. Usually the last step in compiling a program is to run ld.
ld accepts Linker Command Language files written in a superset of AT&T 's Link Editor Command Language syntax, to provide explicit and total control over the linking process.
This man page does not describe the command language; see the ld entry in "info" for full details on the command language and on other aspects of the GNU linker.
This version of ld uses the general purpose BFD libraries to operate on object files. This allows ld to read, combine, and write object files in many different formats−−−for example, COFF or "a.out". Different formats may be linked together to produce any available kind of object file.
Aside from its flexibility, the GNU linker is more helpful than other linkers in providing diagnostic information. Many linkers abandon execution immediately upon encountering an error; whenever possible, ld continues executing, allowing you to identify other errors (or, in some cases, to get an output file in spite of the error).
The GNU linker ld is meant to cover a broad range of situations, and to be as compatible as possible with other linkers. As a result, you have many choices to control its behavior.
Some of the command-line options to ld may be specified at any point in the command line. However, options which refer to files, such as −l or −T, cause the file to be read at the point at which the option appears in the command line, relative to the object files and other file options. Repeating non-file options with a different argument will either have no further effect, or override prior occurrences (those further to the left on the command line) of that option. Options which may be meaningfully specified more than once are noted in the descriptions below.
Non-option arguments are object files or archives which are to be linked together. They may follow, precede, or be mixed in with command-line options, except that an object file argument may not be placed between an option and its argument.
Usually the linker is invoked with at least one object file, but you can specify other forms of binary input files using −l, −R, and the script command language. If no binary input files at all are specified, the linker does not produce any output, and issues the message No input files.
If the linker cannot recognize the format of an object file, it will assume that it is a linker script. A script specified in this way augments the main linker script used for the link (either the default linker script or the one specified by using −T). This feature permits the linker to link against a file which appears to be an object or an archive, but actually merely defines some symbol values, or uses "INPUT" or "GROUP" to load other objects. Specifying a script in this way merely augments the main linker script, with the extra commands placed after the main script; use the −T option to replace the default linker script entirely, but note the effect of the "INSERT" command.
For options whose names are a single letter, option arguments must either follow the option letter without intervening whitespace, or be given as separate arguments immediately following the option that requires them.
For options whose names are multiple letters, either one dash or two can precede the option name; for example, −trace−symbol and −−trace−symbol are equivalent. Note−−−there is one exception to this rule. Multiple letter options that start with a lower case 'o' can only be preceded by two dashes. This is to reduce confusion with the −o option. So for example −omagic sets the output file name to magic whereas −−omagic sets the NMAGIC flag on the output.
Arguments to multiple-letter options must either be separated from the option name by an equals sign, or be given as separate arguments immediately following the option that requires them. For example, −−trace−symbol foo and −−trace−symbol=foo are equivalent. Unique abbreviations of the names of multiple-letter options are accepted.
This option is supported for HP/UX compatibility. The keyword argument must be one of the strings archive, shared, or default. −aarchive is functionally equivalent to −Bstatic, and the other two keywords are functionally equivalent to −Bdynamic. This option may be used any number of times.
Adds AUDITLIB to the "DT_AUDIT" entry of the dynamic section. AUDITLIB is not checked for existence, nor will it use the DT_SONAME specified in the library. If specified multiple times "DT_AUDIT" will contain a colon separated list of audit interfaces to use. If the linker finds an object with an audit entry while searching for shared libraries, it will add a corresponding "DT_DEPAUDIT" entry in the output file. This option is only meaningful on ELF platforms supporting the rtld-audit interface.
In the current release of ld, this option is useful only for the Intel 960 family of architectures. In that ld configuration, the architecture argument identifies the particular architecture in the 960 family, enabling some safeguards and modifying the archive-library search path.
Future releases of ld may support similar functionality for other architecture families.
You may want to use this option if you are linking files with an unusual binary format. You can also use −b to switch formats explicitly (when linking object files of different formats), by including −b input-format before each group of object files in a particular format.
For compatibility with linkers produced by MRI , ld accepts script files written in an alternate, restricted command language, described in the MRI Compatible Script Files section of GNU ld documentation. Introduce MRI script files with the option −c; use the −T option to run linker scripts written in the general-purpose ld scripting language. If MRI-cmdfile does not exist, ld looks for it in the directories specified by any −L options.
These three options are equivalent; multiple forms are supported for compatibility with other linkers. They assign space to common symbols even if a relocatable output file is specified (with −r). The script command "FORCE_COMMON_ALLOCATION" has the same effect.
Adds AUDITLIB to the "DT_DEPAUDIT" entry of the dynamic section. AUDITLIB is not checked for existence, nor will it use the DT_SONAME specified in the library. If specified multiple times "DT_DEPAUDIT" will contain a colon separated list of audit interfaces to use. This option is only meaningful on ELF platforms supporting the rtld-audit interface. The −P option is provided for Solaris compatibility.
Use entry as the explicit symbol for beginning execution of your program, rather than the default entry point. If there is no symbol named entry, the linker will try to parse entry as a number, and use that as the entry address (the number will be interpreted in base 10; you may use a leading 0x for base 16, or a leading 0 for base 8).
Specifies a list of archive libraries from which symbols should not be automatically exported. The library names may be delimited by commas or colons. Specifying "−−exclude−libs ALL" excludes symbols in all archive libraries from automatic export. This option is available only for the i386 PE targeted port of the linker and for ELF targeted ports. For i386 PE , symbols explicitly listed in a .def file are still exported, regardless of this option. For ELF targeted ports, symbols affected by this option will be treated as hidden.
Specifies a list of object files or archive members, from which symbols should not be automatically exported, but which should be copied wholesale into the import library being generated during the link. The module names may be delimited by commas or colons, and must match exactly the filenames used by ld to open the files; for archive members, this is simply the member name, but for object files the name listed must include and match precisely any path used to specify the input file on the linker's command-line. This option is available only for the i386 PE targeted port of the linker. Symbols explicitly listed in a .def file are still exported, regardless of this option.
When creating a dynamically linked executable, using the −E option or the −−export−dynamic option causes the linker to add all symbols to the dynamic symbol table. The dynamic symbol table is the set of symbols which are visible from dynamic objects at run time.
If you do not use either of these options (or use the −−no−export−dynamic option to restore the default behavior), the dynamic symbol table will normally contain only those symbols which are referenced by some dynamic object mentioned in the link.
If you use "dlopen" to load a dynamic object which needs to refer back to the symbols defined by the program, rather than some other dynamic object, then you will probably need to use this option when linking the program itself.
You can also use the dynamic list to control what symbols should be added to the dynamic symbol table if the output format supports it. See the description of −−dynamic−list.
Note that this option is specific to ELF targeted ports. PE targets support a similar function to export all symbols from a DLL or EXE ; see the description of −−export−all−symbols below.
Link big-endian objects. This affects the default output format.
Link little-endian objects. This affects the default output format.
When creating an ELF shared object, set the internal DT_AUXILIARY field to the specified name. This tells the dynamic linker that the symbol table of the shared object should be used as an auxiliary filter on the symbol table of the shared object name.
If you later link a program against this filter object, then, when you run the program, the dynamic linker will see the DT_AUXILIARY field. If the dynamic linker resolves any symbols from the filter object, it will first check whether there is a definition in the shared object name. If there is one, it will be used instead of the definition in the filter object. The shared object name need not exist. Thus the shared object name may be used to provide an alternative implementation of certain functions, perhaps for debugging or for machine specific performance.
This option may be specified more than once. The DT_AUXILIARY entries will be created in the order in which they appear on the command line.
When creating an ELF shared object, set the internal DT_FILTER field to the specified name. This tells the dynamic linker that the symbol table of the shared object which is being created should be used as a filter on the symbol table of the shared object name.
If you later link a program against this filter object, then, when you run the program, the dynamic linker will see the DT_FILTER field. The dynamic linker will resolve symbols according to the symbol table of the filter object as usual, but it will actually link to the definitions found in the shared object name. Thus the filter object can be used to select a subset of the symbols provided by the object name.
Some older linkers used the −F option throughout a compilation toolchain for specifying object-file format for both input and output object files. The GNU linker uses other mechanisms for this purpose: the −b, −−format, −−oformat options, the "TARGET" command in linker scripts, and the "GNUTARGET" environment variable. The GNU linker will ignore the −F option when not creating an ELF shared object.
When creating an ELF executable or shared object, call NAME when the executable or shared object is unloaded, by setting DT_FINI to the address of the function. By default, the linker uses "_fini" as the function to call.
Ignored. Provided for compatibility with other tools.
Set the maximum size of objects to be optimized using the GP register to size. This is only meaningful for object file formats such as MIPS ECOFF which supports putting large and small objects into different sections. This is ignored for other object file formats.
When creating an ELF shared object, set the internal DT_SONAME field to the specified name. When an executable is linked with a shared object which has a DT_SONAME field, then when the executable is run the dynamic linker will attempt to load the shared object specified by the DT_SONAME field rather than the using the file name given to the linker.
Perform an incremental link (same as option −r).
When creating an ELF executable or shared object, call NAME when the executable or shared object is loaded, by setting DT_INIT to the address of the function. By default, the linker uses "_init" as the function to call.
Add the archive or object file specified by namespec to the list of files to link. This option may be used any number of times. If namespec is of the form :filename, ld will search the library path for a file called filename, otherwise it will search the library path for a file called libnamespec.a.
On systems which support shared libraries, ld may also search for files other than libnamespec.a. Specifically, on ELF and SunOS systems, ld will search a directory for a library called libnamespec.so before searching for one called libnamespec.a. (By convention, a ".so" extension indicates a shared library.) Note that this behavior does not apply to :filename, which always specifies a file called filename.
The linker will search an archive only once, at the location where it is specified on the command line. If the archive defines a symbol which was undefined in some object which appeared before the archive on the command line, the linker will include the appropriate file(s) from the archive. However, an undefined symbol in an object appearing later on the command line will not cause the linker to search the archive again.
See the −( option for a way to force the linker to search archives multiple times.
This type of archive searching is standard for Unix linkers. However, if you are using ld on AIX , note that it is different from the behaviour of the AIX linker.
Add path searchdir to the list of paths that ld will search for archive libraries and ld control scripts. You may use this option any number of times. The directories are searched in the order in which they are specified on the command line. Directories specified on the command line are searched before the default directories. All −L options apply to all −l options, regardless of the order in which the options appear. −L options do not affect how ld searches for a linker script unless −T option is specified.
If searchdir begins with "=", then the "=" will be replaced by the sysroot prefix, a path specified when the linker is configured.
The default set of paths searched (without being specified with −L) depends on which emulation mode ld is using, and in some cases also on how it was configured.
The paths can also be specified in a link script with the "SEARCH_DIR" command. Directories specified this way are searched at the point in which the linker script appears in the command line.
Emulate the emulation linker. You can list the available emulations with the −−verbose or −V options.
If the −m option is not used, the emulation is taken from the "LDEMULATION" environment variable, if that is defined.
Where object files are mapped into memory.
How common symbols are allocated.
All archive members included in the link, with a mention of the symbol which caused the archive member to be brought in.
The values assigned to symbols.
Turn off page alignment of sections, and disable linking against shared libraries. If the output format supports Unix style magic numbers, mark the output as "NMAGIC".
Set the text and data sections to be readable and writable. Also, do not page-align the data segment, and disable linking against shared libraries. If the output format supports Unix style magic numbers, mark the output as "OMAGIC". Note: Although a writable text section is allowed for PE-COFF targets, it does not conform to the format specification published by Microsoft.
This option negates most of the effects of the −N option. It sets the text section to be read-only, and forces the data segment to be page-aligned. Note − this option does not enable linking against shared libraries. Use −Bdynamic for this.
Use output as the name for the program produced by ld; if this option is not specified, the name a.out is used by default. The script command "OUTPUT" can also specify the output file name.
If level is a numeric values greater than zero ld optimizes the output. This might take significantly longer and therefore probably should only be enabled for the final binary. At the moment this option only affects ELF shared library generation. Future releases of the linker may make more use of this option. Also currently there is no difference in the linker's behaviour for different non-zero values of this option. Again this may change with future releases.
Leave relocation sections and contents in fully linked executables. Post link analysis and optimization tools may need this information in order to perform correct modifications of executables. This results in larger executables.
Force the output file to have dynamic sections. This option is specific to VxWorks targets.
Generate relocatable output−−−i.e., generate an output file that can in turn serve as input to ld. This is often called partial linking. As a side effect, in environments that support standard Unix magic numbers, this option also sets the output file's magic number to "OMAGIC". If this option is not specified, an absolute file is produced. When linking C ++ programs, this option will not resolve references to constructors; to do that, use −Ur.
When an input file does not have the same format as the output file, partial linking is only supported if that input file does not contain any relocations. Different output formats can have further restrictions; for example some "a.out"−based formats do not support partial linking with input files in other formats at all.
This option does the same thing as −i.
Read symbol names and their addresses from filename, but do not relocate it or include it in the output. This allows your output file to refer symbolically to absolute locations of memory defined in other programs. You may use this option more than once.
For compatibility with other ELF linkers, if the −R option is followed by a directory name, rather than a file name, it is treated as the −rpath option.
Use scriptfile as the linker script. This script replaces ld's default linker script (rather than adding to it), so commandfile must specify everything necessary to describe the output file. If scriptfile does not exist in the current directory, "ld" looks for it in the directories specified by any preceding −L options. Multiple −T options accumulate.
This option is similar to the −−script option except that processing of the script is delayed until after the rest of the command line has been processed. This allows options placed after the −−default−script option on the command line to affect the behaviour of the linker script, which can be important when the linker command line cannot be directly controlled by the user. (eg because the command line is being constructed by another tool, such as gcc).
Force symbol to be entered in the output file as an undefined symbol. Doing this may, for example, trigger linking of additional modules from standard libraries. −u may be repeated with different option arguments to enter additional undefined symbols. This option is equivalent to the "EXTERN" linker script command.
For anything other than C ++ programs, this option is equivalent to −r: it generates relocatable output−−−i.e., an output file that can in turn serve as input to ld. When linking C ++ programs, −Ur does resolve references to constructors, unlike −r. It does not work to use −Ur on files that were themselves linked with −Ur; once the constructor table has been built, it cannot be added to. Use −Ur only for the last partial link, and −r for the others.
Creates a separate output section for every input section matching SECTION , or if the optional wildcard SECTION argument is missing, for every orphan input section. An orphan section is one not specifically mentioned in a linker script. You may use this option multiple times on the command line; It prevents the normal merging of input sections with the same name, overriding output section assignments in a linker script.
Display the version number for ld. The −V option also lists the supported emulations.
Print the name of each linked file in which symbol appears. This option may be given any number of times. On many systems it is necessary to prepend an underscore.
This option is useful when you have an undefined symbol in your link but don't know where the reference is coming from.
Add path to the default library search path. This option exists for Solaris compatibility.
Combines multiple reloc sections and sorts them to make dynamic symbol lookup caching possible.
Disallows undefined symbols in object files. Undefined symbols in shared libraries are still allowed.
This option is only meaningful when building a shared object. It marks the object so that its runtime initialization will occur before the runtime initialization of any other objects brought into the process at the same time. Similarly the runtime finalization of the object will occur after the runtime finalization of any other objects.
Marks the object that its symbol table interposes before all symbols but the primary executable.
When generating an executable or shared library, mark it to tell the dynamic linker to defer function call resolution to the point when the function is called (lazy binding), rather than at load time. Lazy binding is the default.
Marks the object that its filters be processed immediately at runtime.
Marks the object that the search for dependencies of this object will ignore any default library search paths.
Marks the object shouldn't be unloaded at runtime.
Don't create an ELF "PT_GNU_RELRO" segment header in the object.
When generating an executable or shared library, mark it to tell the dynamic linker to resolve all symbols when the program is started, or when the shared library is linked to using dlopen, instead of deferring function call resolution to the point when the function is first called.
The archives should be a list of archive files. They may be either explicit file names, or −l options.
Tells the linker to accept input files whose architecture cannot be recognised. The assumption is that the user knows what they are doing and deliberately wants to link in these unknown input files. This was the default behaviour of the linker, before release 2.14. The default behaviour from release 2.14 onwards is to reject such input files, and so the −−accept−unknown−input−arch option has been added to restore the old behaviour.
This option affects ELF DT_NEEDED tags for dynamic libraries mentioned on the command line after the −−as−needed option. Normally the linker will add a DT_NEEDED tag for each dynamic library mentioned on the command line, regardless of whether the library is actually needed or not. −−as−needed causes a DT_NEEDED tag to only be emitted for a library that satisfies an undefined symbol reference from a regular object file or, if the library is not found in the DT_NEEDED lists of other libraries linked up to that point, an undefined symbol reference from another dynamic library. −−no−as−needed restores the default behaviour.
These two options have been deprecated because of the similarity of their names to the −−as−needed and −−no−as−needed options. They have been replaced by −−copy−dt−needed−entries and −−no−copy−dt−needed−entries.
Link against dynamic libraries. This is only meaningful on platforms for which shared libraries are supported. This option is normally the default on such platforms. The different variants of this option are for compatibility with various systems. You may use this option multiple times on the command line: it affects library searching for −l options which follow it.
Set the "DF_1_GROUP" flag in the "DT_FLAGS_1" entry in the dynamic section. This causes the runtime linker to handle lookups in this object and its dependencies to be performed only inside the group. −−unresolved−symbols=report−all is implied. This option is only meaningful on ELF platforms which support shared libraries.
Do not link against shared libraries. This is only meaningful on platforms for which shared libraries are supported. The different variants of this option are for compatibility with various systems. You may use this option multiple times on the command line: it affects library searching for −l options which follow it. This option also implies −−unresolved−symbols=report−all. This option can be used with −shared. Doing so means that a shared library is being created but that all of the library's external references must be resolved by pulling in entries from static libraries.
When creating a shared library, bind references to global symbols to the definition within the shared library, if any. Normally, it is possible for a program linked against a shared library to override the definition within the shared library. This option is only meaningful on ELF platforms which support shared libraries.
When creating a shared library, bind references to global function symbols to the definition within the shared library, if any. This option is only meaningful on ELF platforms which support shared libraries.
Specify the name of a dynamic list file to the linker. This is typically used when creating shared libraries to specify a list of global symbols whose references shouldn't be bound to the definition within the shared library, or creating dynamically linked executables to specify a list of symbols which should be added to the symbol table in the executable. This option is only meaningful on ELF platforms which support shared libraries.
The format of the dynamic list is the same as the version node without scope and node name. See VERSION for more information.
Provide the builtin dynamic list for C ++ operator new and delete. It is mainly useful for building shared libstdc++.
Provide the builtin dynamic list for C ++ runtime type identification.
Asks the linker not to check section addresses after they have been assigned to see if there are any overlaps. Normally the linker will perform this check, and if it finds any overlaps it will produce suitable error messages. The linker does know about, and does make allowances for sections in overlays. The default behaviour can be restored by using the command line switch −−check−sections. Section overlap is not usually checked for relocatable links. You can force checking in that case by using the −−check−sections option.
This option affects the treatment of dynamic libraries referred to by DT_NEEDED tags inside ELF dynamic libraries mentioned on the command line. Normally the linker won't add a DT_NEEDED tag to the output binary for each library mentioned in a DT_NEEDED tag in an input dynamic library. With −−copy−dt−needed−entries specified on the command line however any dynamic libraries that follow it will have their DT_NEEDED entries added. The default behaviour can be restored with −−no−copy−dt−needed−entries.
This option also has an effect on the resolution of symbols in dynamic libraries. With −−copy−dt−needed−entries dynamic libraries mentioned on the command line will be recursively searched, following their DT_NEEDED tags to other libraries, in order to resolve symbols required by the output binary. With the default setting however the searching of dynamic libraries that follow it will stop with the dynamic library itself. No DT_NEEDED links will be traversed to resolve symbols.
Output a cross reference table. If a linker map file is being generated, the cross reference table is printed to the map file. Otherwise, it is printed on the standard output.
The format of the table is intentionally simple, so that it may be easily processed by a script if necessary. The symbols are printed out, sorted by name. For each symbol, a list of file names is given. If the symbol is defined, the first file listed is the location of the definition. The remaining files contain references to the symbol.
This option inhibits the assignment of addresses to common symbols. The script command "INHIBIT_COMMON_ALLOCATION" has the same effect.
The −−no−define−common option allows decoupling the decision to assign addresses to Common symbols from the choice of the output file type; otherwise a non-Relocatable output type forces assigning addresses to Common symbols. Using −−no−define−common allows Common symbols that are referenced from a shared library to be assigned addresses only in the main program. This eliminates the unused duplicate space in the shared library, and also prevents any possible confusion over resolving to the wrong duplicate when there are many dynamic modules with specialized search paths for runtime symbol resolution.
Create a global symbol in the output file, containing the absolute address given by expression. You may use this option as many times as necessary to define multiple symbols in the command line. A limited form of arithmetic is supported for the expression in this context: you may give a hexadecimal constant or the name of an existing symbol, or use "+" and "−" to add or subtract hexadecimal constants or symbols. If you need more elaborate expressions, consider using the linker command language from a script. Note: there should be no white space between symbol, the equals sign ("="), and expression.
These options control whether to demangle symbol names in error messages and other output. When the linker is told to demangle, it tries to present symbol names in a readable fashion: it strips leading underscores if they are used by the object file format, and converts C ++ mangled symbol names into user readable names. Different compilers have different mangling styles. The optional demangling style argument can be used to choose an appropriate demangling style for your compiler. The linker will demangle by default unless the environment variable COLLECT_NO_DEMANGLE is set. These options may be used to override the default.
Set the name of the dynamic linker. This is only meaningful when generating dynamically linked ELF executables. The default dynamic linker is normally correct; don't use this unless you know what you are doing.
Treat all warnings as errors. The default behaviour can be restored with the option −−no−fatal−warnings.
If a successfully built fully linked output file does not have a ".exe" or ".dll" suffix, this option forces the linker to copy the output file to one of the same name with a ".exe" suffix. This option is useful when using unmodified Unix makefiles on a Microsoft Windows host, since some versions of Windows won't run an image unless it ends in a ".exe" suffix.
Enable garbage collection of unused input sections. It is ignored on targets that do not support this option. The default behaviour (of not performing this garbage collection) can be restored by specifying −−no−gc−sections on the command line.
−−gc−sections decides which input sections are used by examining symbols and relocations. The section containing the entry symbol and all sections containing symbols undefined on the command-line will be kept, as will sections containing symbols referenced by dynamic objects. Note that when building shared libraries, the linker must assume that any visible symbol is referenced. Once this initial set of sections has been determined, the linker recursively marks as used any section referenced by their relocations. See −−entry and −−undefined.
This option can be set when doing a partial link (enabled with option −r). In this case the root of symbols kept must be explicitly specified either by an −−entry or −−undefined option or by a "ENTRY" command in the linker script.
List all sections removed by garbage collection. The listing is printed on stderr. This option is only effective if garbage collection has been enabled via the −−gc−sections) option. The default behaviour (of not listing the sections that are removed) can be restored by specifying −−no−print−gc−sections on the command line.
Print the name of the default output format (perhaps influenced by other command-line options). This is the string that would appear in an "OUTPUT_FORMAT" linker script command.
Print a link map to the file mapfile. See the description of the −M option, above.
ld normally optimizes for speed over memory usage by caching the symbol tables of input files in memory. This option tells ld to instead optimize for memory usage, by rereading the symbol tables as necessary. This may be required if ld runs out of memory space while linking a large executable.
Report unresolved symbol references from regular object files. This is done even if the linker is creating a non-symbolic shared library. The switch −−[no−]allow−shlib−undefined controls the behaviour for reporting unresolved references found in shared libraries being linked in.
Normally when a symbol is defined multiple times, the linker will report a fatal error. These options allow multiple definitions and the first definition will be used.
Allows or disallows undefined symbols in shared libraries. This switch is similar to −−no−undefined except that it determines the behaviour when the undefined symbols are in a shared library rather than a regular object file. It does not affect how undefined symbols in regular object files are handled.
The default behaviour is to report errors for any undefined symbols referenced in shared libraries if the linker is being used to create an executable, but to allow them if the linker is being used to create a shared library.
A shared library specified at link time may not be the same as the one that is available at load time, so the symbol might actually be resolvable at load time.
There are some operating systems, eg BeOS and HPPA , where undefined symbols in shared libraries are normal.
The BeOS kernel for example patches shared libraries at load time to select whichever function is most appropriate for the current architecture. This is used, for example, to dynamically select an appropriate memset function.
Normally when a symbol has an undefined version, the linker will ignore it. This option disallows symbols with undefined version and a fatal error will be issued instead.
Normally ld will give an error if you try to link together input files that are mismatched for some reason, perhaps because they have been compiled for different processors or for different endiannesses. This option tells ld that it should silently permit such possible errors. This option should only be used with care, in cases when you have taken some special action that ensures that the linker errors are inappropriate.
Normally ld will give a warning if it finds an incompatible library during a library search. This option silences the warning.
Turn off the effect of the −−whole−archive option for subsequent archive files.
Retain the executable output file whenever it is still usable. Normally, the linker will not produce an output file if it encounters errors during the link process; it exits without writing an output file when it issues any error whatsoever.
Only search library directories explicitly specified on the command line. Library directories specified in linker scripts (including linker scripts specified on the command line) are ignored.
ld may be configured to support more than one kind of object file. If your ld is configured this way, you can use the −−oformat option to specify the binary format for the output object file. Even when ld is configured to support alternative object formats, you don't usually need to specify this, as ld should be configured to produce as a default output format the most usual format on each machine. output-format is a text string, the name of a particular format supported by the BFD libraries. (You can list the available binary formats with objdump −i.) The script command "OUTPUT_FORMAT" can also specify the output format, but this option overrides it.
Create a position independent executable. This is currently only supported on ELF platforms. Position independent executables are similar to shared libraries in that they are relocated by the dynamic linker to the virtual address the OS chooses for them (which can vary between invocations). Like normal dynamically linked executables they can be executed and symbols defined in the executable cannot be overridden by shared libraries.
This option is ignored for SVR4 compatibility.
An option with machine dependent effects. This option is only supported on a few targets.
On some platforms the −−relax option performs target specific, global optimizations that become possible when the linker resolves addressing in the program, such as relaxing address modes, synthesizing new instructions, selecting shorter version of current instructions, and combinig constant values.
On some platforms these link time global optimizations may make symbolic debugging of the resulting executable impossible. This is known to be the case for the Matsushita MN10200 and MN10300 family of processors.
On platforms where this is not supported, −−relax is accepted, but ignored.
On platforms where −−relax is accepted the option −−no−relax can be used to disable the feature.
Retain only the symbols listed in the file filename, discarding all others. filename is simply a flat file, with one symbol name per line. This option is especially useful in environments (such as VxWorks) where a large global symbol table is accumulated gradually, to conserve run-time memory.
−−retain−symbols−file does not discard undefined symbols, or symbols needed for relocations.
You may only specify −−retain−symbols−file once in the command line. It overrides −s and −S.
Add a directory to the runtime library search path. This is used when linking an ELF executable with shared objects. All −rpath arguments are concatenated and passed to the runtime linker, which uses them to locate shared objects at runtime. The −rpath option is also used when locating shared objects which are needed by shared objects explicitly included in the link; see the description of the −rpath−link option. If −rpath is not used when linking an ELF executable, the contents of the environment variable "LD_RUN_PATH" will be used if it is defined.
The −rpath option may also be used on SunOS. By default, on SunOS, the linker will form a runtime search patch out of all the −L options it is given. If a −rpath option is used, the runtime search path will be formed exclusively using the −rpath options, ignoring the −L options. This can be useful when using gcc, which adds many −L options which may be on NFS mounted file systems.
When using ELF or SunOS, one shared library may require another. This happens when an "ld −shared" link includes a shared library as one of the input files.
When the linker encounters such a dependency when doing a non-shared, non-relocatable link, it will automatically try to locate the required shared library and include it in the link, if it is not included explicitly. In such a case, the −rpath−link option specifies the first set of directories to search. The −rpath−link option may specify a sequence of directory names either by specifying a list of names separated by colons, or by appearing multiple times.
This option should be used with caution as it overrides the search path that may have been hard compiled into a shared library. In such a case it is possible to use unintentionally a different search path than the runtime linker would do.
Any directories specified by −rpath−link options.
Any directories specified by −rpath options. The difference between −rpath and −rpath−link is that directories specified by −rpath options are included in the executable and used at runtime, whereas the −rpath−link option is only effective at link time. Searching −rpath in this way is only supported by native linkers and cross linkers which have been configured with the −−with−sysroot option.
On an ELF system, for native linkers, if the −rpath and −rpath−link options were not used, search the contents of the environment variable "LD_RUN_PATH".
On SunOS, if the −rpath option was not used, search any directories specified using −L options.
For a native linker, the search the contents of the environment variable "LD_LIBRARY_PATH".
For a native ELF linker, the directories in "DT_RUNPATH" or "DT_RPATH" of a shared library are searched for shared libraries needed by it. The "DT_RPATH" entries are ignored if "DT_RUNPATH" entries exist.
The default directories, normally /lib and /usr/lib.
For a native linker on an ELF system, if the file /etc/ld.so.conf exists, the list of directories found in that file.
If the required shared library is not found, the linker will issue a warning and continue with the link.
Create a shared library. This is currently only supported on ELF , XCOFF and SunOS platforms. On SunOS, the linker will automatically create a shared library if the −e option is not used and there are undefined symbols in the link.
This option tells ld to sort the common symbols by alignment in ascending or descending order when it places them in the appropriate output sections. The symbol alignments considered are sixteen-byte or larger, eight-byte, four-byte, two-byte, and one-byte. This is to prevent gaps between symbols due to alignment constraints. If no sorting order is specified, then descending order is assumed.
This option will apply "SORT_BY_NAME" to all wildcard section patterns in the linker script.
This option will apply "SORT_BY_ALIGNMENT" to all wildcard section patterns in the linker script.
Similar to −−split−by−reloc but creates a new output section for each input file when size is reached. size defaults to a size of 1 if not given.
Tries to creates extra sections in the output file so that no single output section in the file contains more than count relocations. This is useful when generating huge relocatable files for downloading into certain real time kernels with the COFF object file format; since COFF cannot represent more than 65535 relocations in a single section. Note that this will fail to work with object file formats which do not support arbitrary sections. The linker will not split up individual input sections for redistribution, so if a single input section contains more than count relocations one output section will contain that many relocations. count defaults to a value of 32768.
Compute and display statistics about the operation of the linker, such as execution time and memory usage.
Use directory as the location of the sysroot, overriding the configure-time default. This option is only supported by linkers that were configured using −−with−sysroot.
For some targets, the output of ld is different in some ways from the output of some existing linker. This switch requests ld to use the traditional format instead.
For example, on SunOS, ld combines duplicate entries in the symbol string table. This can reduce the size of an output file with full debugging information by over 30 percent. Unfortunately, the SunOS "dbx" program can not read the resulting program ("gdb" has no trouble). The −−traditional−format switch tells ld to not combine duplicate entries.
Locate a section in the output file at the absolute address given by org. You may use this option as many times as necessary to locate multiple sections in the command line. org must be a single hexadecimal integer; for compatibility with other linkers, you may omit the leading 0x usually associated with hexadecimal values. Note: there should be no white space between sectionname, the equals sign ("="), and org.
Same as −−section−start, with ".bss", ".data" or ".text" as the sectionname.
When creating an ELF executable or shared object, it will set the address of the first byte of the text segment.
When creating an ELF executable or shared object for a target where the read-only data is in its own segment separate from the executable text, it will set the address of the first byte of the read-only data segment.
Report all unresolved symbols. This is the default.
Report unresolved symbols that are contained in shared libraries, but ignore them if they come from regular object files.
Report unresolved symbols that come from regular object files, but ignore them if they come from shared libraries. This can be useful when creating a dynamic binary and it is known that all the shared libraries that it should be referencing are included on the linker's command line.
The behaviour for shared libraries on their own can also be controlled by the −−[no−]allow−shlib−undefined option.
Normally the linker will generate an error message for each reported unresolved symbol but the option −−warn−unresolved−symbols can change this to a warning.
Display the version number for ld and list the linker emulations supported. Display which input files can and cannot be opened. Display the linker script being used by the linker. If the optional NUMBER argument > 1, plugin symbol status will also be displayed.
Specify the name of a version script to the linker. This is typically used when creating shared libraries to specify additional information about the version hierarchy for the library being created. This option is only fully supported on ELF platforms which support shared libraries; see VERSION . It is partially supported on PE platforms, which can use version scripts to filter symbol visibility in auto-export mode: any symbols marked local in the version script will not be exported.
Warn when a common symbol is combined with another common symbol or with a symbol definition. Unix linkers allow this somewhat sloppy practise, but linkers on some other operating systems do not. This option allows you to find potential problems from combining global symbols. Unfortunately, some C libraries use this practise, so you may get some warnings about symbols in the libraries as well as in your programs.
An undefined reference, which does not allocate space. There must be either a definition or a common symbol for the variable somewhere.
A common symbol. If there are only (one or more) common symbols for a variable, it goes in the uninitialized data area of the output file. The linker merges multiple common symbols for the same variable into a single symbol. If they are of different sizes, it picks the largest size. The linker turns a common symbol into a declaration, if there is a definition of the same variable.
The −−warn−common option can produce five kinds of warnings. Each warning consists of a pair of lines: the first describes the symbol just encountered, and the second describes the previous symbol encountered with the same name. One or both of the two symbols will be a common symbol.
Turning a common symbol into a reference, because there is already a definition for the symbol.
Turning a common symbol into a reference, because a later definition for the symbol is encountered. This is the same as the previous case, except that the symbols are encountered in a different order.
Merging a common symbol with a previous same-sized common symbol.
Merging a common symbol with a previous larger common symbol.
Merging a common symbol with a previous smaller common symbol. This is the same as the previous case, except that the symbols are encountered in a different order.
Warn if any global constructors are used. This is only useful for a few object file formats. For formats like COFF or ELF , the linker can not detect the use of global constructors.
Warn if multiple global pointer values are required in the output file. This is only meaningful for certain processors, such as the Alpha. Specifically, some processors put large-valued constants in a special section. A special register (the global pointer) points into the middle of this section, so that constants can be loaded efficiently via a base-register relative addressing mode. Since the offset in base-register relative mode is fixed and relatively small (e.g., 16 bits), this limits the maximum size of the constant pool. Thus, in large programs, it is often necessary to use multiple global pointer values in order to be able to address all possible constants. This option causes a warning to be issued whenever this case occurs.
Only warn once for each undefined symbol, rather than once per module which refers to it.
Warn if the address of an output section is changed because of alignment. Typically, the alignment will be set by an input section. The address will only be changed if it not explicitly specified; that is, if the "SECTIONS" command does not specify a start address for the section.
If the linker is going to report an unresolved symbol (see the option −−unresolved−symbols) it will normally generate an error. This option makes it generate a warning instead.
This restores the linker's default behaviour of generating errors when it is reporting unresolved symbols.
For each archive mentioned on the command line after the −−whole−archive option, include every object file in the archive in the link, rather than searching the archive for the required object files. This is normally used to turn an archive file into a shared library, forcing every object to be included in the resulting shared library. This option may be used more than once.
Two notes when using this option from gcc: First, gcc doesn't know about this option, so you have to use −Wl,−whole−archive. Second, don't forget to use −Wl,−no−whole−archive after your list of archives, because gcc will add its own list of archives to your link and you may not want this flag to affect those as well.
Use a wrapper function for symbol. Any undefined reference to symbol will be resolved to "__wrap_symbol". Any undefined reference to "__real_symbol" will be resolved to symbol.
This can be used to provide a wrapper for a system function. The wrapper function should be called "__wrap_symbol". If it wishes to call the system function, it should call "__real_symbol".
If you link other code with this file using −−wrap malloc, then all calls to "malloc" will call the function "__wrap_malloc" instead. The call to "__real_malloc" in "__wrap_malloc" will call the real "malloc" function.
You may wish to provide a "__real_malloc" function as well, so that links without the −−wrap option will succeed. If you do this, you should not put the definition of "__real_malloc" in the same file as "__wrap_malloc"; if you do, the assembler may resolve the call before the linker has a chance to wrap it to "malloc".
Request creation of ".eh_frame" unwind info for linker generated code sections like PLT . This option is on by default if linker generated unwind info is supported.
This linker can create the new dynamic tags in ELF . But the older ELF systems may not understand them. If you specify −−enable−new−dtags, the dynamic tags will be created as needed. If you specify −−disable−new−dtags, no new dynamic tags will be created. By default, the new dynamic tags are not created. Note that those options are only available for ELF systems.
Set the default size of the linker's hash tables to a prime number close to number. Increasing this value can reduce the length of time it takes the linker to perform its tasks, at the expense of increasing the linker's memory requirements. Similarly reducing this value can reduce the memory requirements at the expense of speed.
Set the type of linker's hash table(s). style can be either "sysv" for classic ELF ".hash" section, "gnu" for new style GNU ".gnu.hash" section or "both" for both the classic ELF ".hash" and new style GNU ".gnu.hash" hash tables. The default is "sysv".
This option reduces memory requirements at ld runtime, at the expense of linking speed. This was introduced to select the old O(n^2) algorithm for link map file generation, rather than the new O(n) algorithm which uses about 40% more memory for symbol storage.
Another effect of the switch is to set the default hash table size to 1021, which again saves memory at the cost of lengthening the linker's run time. This is not done however if the −−hash−size switch has been used.
The −−reduce−memory−overheads switch may be also be used to enable other tradeoffs in future versions of the linker.
Request creation of ".note.gnu.build−id" ELF note section. The contents of the note are unique bits identifying this linked file. style can be "uuid" to use 128 random bits, "sha1" to use a 160−bit SHA1 hash on the normative parts of the output contents, "md5" to use a 128−bit MD5 hash on the normative parts of the output contents, or "0xhexstring" to use a chosen bit string specified as an even number of hexadecimal digits ("−" and ":" characters between digit pairs are ignored). If style is omitted, "sha1" is used.
The "md5" and "sha1" styles produces an identifier that is always the same in an identical output file, but will be unique among all nonidentical output files. It is not intended to be compared as a checksum for the file's contents. A linked file may be changed later by other tools, but the build ID bit string identifying the original linked file does not change.
Passing "none" for style disables the setting from any "−−build−id" options earlier on the command line.
The i386 PE linker supports the −shared option, which causes the output to be a dynamically linked library ( DLL ) instead of a normal executable. You should name the output "*.dll" when you use this option. In addition, the linker fully supports the standard "*.def" files, which may be specified on the linker command line like an object file (in fact, it should precede archives it exports symbols from, to ensure that they get linked in, just like a normal object file).
In addition to the options common to all targets, the i386 PE linker support additional command line options that are specific to the i386 PE target. Options that take values may be separated from their values by either a space or an equals sign.
For most targets default symbol-prefix is an underscore and is defined in target's description. By this option it is possible to disable/enable the default underscore symbol-prefix.
Do sophisticated linking of "_symbol" to "__imp__symbol" for DATA imports from DLLs, and create the necessary thunking symbols when building the import libraries with those DATA exports. Note: Use of the 'auto−import' extension will cause the text section of the image file to be made writable. This does not conform to the PE-COFF format specification published by Microsoft.
"variable '<var>' can't be auto-imported. Please read the documentation for ld's "−−enable−auto−import" for details."
This message occurs when some (sub)expression accesses an address ultimately given by the sum of two constants (Win32 import tables only allow one). Instances where this may occur include accesses to member fields of struct variables imported from a DLL , as well as using a constant index into an array variable imported from a DLL . Any multiword variable (arrays, structs, long long, etc) may trigger this error condition. However, regardless of the exact data type of the offending exported variable, ld will always detect it, issue the warning, and exit.
One way is to use −−enable−runtime−pseudo−reloc switch. This leaves the task of adjusting references in your client code for runtime environment, so this method works only when runtime environment supports this feature.
The image base address may be relocated using address space layout randomization ( ASLR ). This feature was introduced with MS Windows Vista for i386 PE targets.
The image is compatible with the Data Execution Prevention. This feature was introduced with MS Windows XP SP2 for i386 PE targets.
The image does not use SEH . No SE handler may be called from this image.
The C6X uClinux target uses a binary format called DSBT to support shared libraries. Each shared library in the system needs to have a unique index; all executables use an index of 0.
This option sets the number of entires in the DSBT of the current executable or shared library to size. The default is to create a table with 64 entries.
This option sets the DSBT index of the current executable or shared library to index. The default is 0, which is appropriate for generating executables. If a shared library is generated with a DSBT index of 0, the "R_C6000_DSBT_INDEX" relocs are copied into the output file.
The −−no−merge−exidx−entries switch disables the merging of adjacent exidx entries in frame unwind info.
The 68HC11 and 68HC12 linkers support specific options to control the memory bank switching mapping and trampoline code generation.
This option disables the generation of trampoline. By default a trampoline is generated for each far function which is called using a "jsr" instruction (this happens when a pointer to a far function is taken).
This option indicates to the linker the name of the memory region in the MEMORY specification that describes the memory bank window. The definition of such region is then used by the linker to compute paging and addresses within the memory window.
The following options are supported to control handling of GOT generation when linking for 68K targets.
This option tells the linker which GOT generation scheme to use. type should be one of single, negative, multigot or target. For more information refer to the Info entry for ld.
You can change the behaviour of ld with the environment variables "GNUTARGET", "LDEMULATION" and "COLLECT_NO_DEMANGLE".
"GNUTARGET" determines the input-file object format if you don't use −b (or its synonym −−format). Its value should be one of the BFD names for an input format. If there is no "GNUTARGET" in the environment, ld uses the natural format of the target. If "GNUTARGET" is set to "default" then BFD attempts to discover the input format by examining binary input files; this method often succeeds, but there are potential ambiguities, since there is no method of ensuring that the magic number used to specify object-file formats is unique. However, the configuration procedure for BFD on each system places the conventional format for that system first in the search-list, so ambiguities are resolved in favor of convention.
"LDEMULATION" determines the default emulation if you don't use the −m option. The emulation can affect various aspects of linker behaviour, particularly the default linker script. You can list the available emulations with the −−verbose or −V options. If the −m option is not used, and the "LDEMULATION" environment variable is not defined, the default emulation depends upon how the linker was configured.
Normally, the linker will default to demangling symbols. However, if "COLLECT_NO_DEMANGLE" is set in the environment, then it will default to not demangling symbols. This environment variable is used in a similar fashion by the "gcc" linker wrapper program. The default may be overridden by the −−demangle and −−no−demangle options.

Location : Fakenham
When I left school I applied for a job on the railway & also at an electricians but due to their circumstances I didn't get them.
In February 1952 at the age of 16 I began work at Wyman & Sons Ltd whose printing works was then situated on the west side of White Horse St. I was living at Whissonsett which meant I had a five mile bicycle ride to Fakenham – not excessive at the time. What was not so good was having to bike to work in all weathers, summer & winter The hours we worked were 8 till 5.0 most of the time. It was a job & we were all glad of a job at that time.
I was apprenticed for five years as a Hand Compositor. At that time discipline was such that apprentices were required to address the tradesmen as "Mr." not to use first names. Also smoking was prohibited, so some of the men took snuff. I found it most unpleasant myself when I tried it. It tended to get all over the place, on the equipment & that, & many of the gentlemen's aprons & duster coats were stiff due to wiping their fingers after taking it.
My starting wage was 30/- per week. It would be difficult to describe my work as there are many terms in print that would not be clear to laymen. Suffice to say it involved preparing hot-metal type for printing. A visit to a printing museum would make this clear.
In the 1960s my department moved to a new building on the opposite side of the road. Also at about this time the firm was taken over by the Thomas Tilling group and its name changed to Cox & Wyman. In the 1970s the firm was again taken over, this time by Richard Clay of Bungay an old established printing firm. As new techniques Photosetting and Lithographic printing were now well established it was decided to phase out hot metal which meant redundancies and retraining.
I retrained as a Reader which involved checking that work was correct before printing. Then in 1982 Fakenham closed and all were made redundant, which was a bitter blow to all of us.
Six of my colleagues & I bought up all the Photosetting equipment and started our own firm Fakenham Photosetting Ltd. Of course techniques have continually changed over the years but we have always been able to keep up with new technology. Basically nowadays a disc with the authors words & spaces goes in one end and a disc containing a complete book goes out the other, to the printer.
I retired in 2000 but I still remain a director and occasionally do reading at busy times.
What I enjoyed about my working life was actually seeing the finished product, the book on the bookshelves. In my time off I played football & cricket for the village or watched Norwich City or Peterborough United.

This Course seeks the student to optimize and improve its graphic expression, taking the opportunity to explore the techniques of representation with which it identifies more. It is also intended to provide the student a method of representation through which distinguish the different values that articulate both the design process and the relationship of the forms and the city itself.
It is intended to provide the mechanisms for conceptual and graphics capabilities for design, carry out the analysis of works of great contemporary artists, studying their charts, competitions and the best way to present them.
Develop the ability to analyze and represent, to know and understand the models, reflect on the key aspects of its configuration, indicating what the criteria are to be elected in their representation .
Provide the student with a representation method, in order to distinguish the values that articulate the process, considering the elements that constitute their reality.
Analyze the design in its possibilities, in the design or design of the natural. Start the student in forming proper habits to improve imagination and architectural creativity.
The teaching methodology is based on two major groups: the research and design . Through research, balized and contextualized in lectures, leads the student to the understanding of the method of professionals recognized worldwide for his work and contribution to the scientific area in question. The drawing introduces the student in the field of observation, thought, production and representation.
The program is based on two types of exercises: the first one, where the student will exercise urban analysis, anchored on the field of the course of Architecture II. The various exercises will form the basis to the practice the different graphic techniques in the treatment of expressive forms with feature to the line, to stain, to color, to relations clear/dark, to textures, sketches, rigorous design, rigorous perspective and drawing by hand raised. On the other, the student contact with graphical analysis exercises relevant architects works of all time (which is distinguished by a particular way of thinking and represent the architecture), in order to interpret some concepts such as geometric volumes, masses, textures, color, relationship light/dark, architecture and geometry, organic forms, architecture and nature.
All these concepts are explained, especially in lectures, in accordance with the exercises, so that conclusively the Course offers students the awareness of architecture and the importance of representation, as intelectualizante material from different ways of thinking and projecting .

After Maruti Vitara and Tata H5X, MG SUV too will come with Fiat 2.0 engine
Fiat's Multijet engine is currently used by many manufacturers in India to power their vehicles. Fiat introduced the 2.0-litre Multijet engine in India with the Compass and soon other manufacturers will soon use the engine in their vehicles. MG Motor India, a new manufacturer that will launch its first product in the form of compact SUV – ZS. As per reports, the car will be powered by Fiat's 2.0-litre Multijet engine. This is the same engine that will be used in Maruti Vitara and Tata H5X in the future too.
Due to the increasing demands of the SUVs in India, MG Motors will foray into the Indian market with a soft-roader. The vehicles will be made in the Gujarat plant that the company took over from General Motors. TOI's report says that SIAC, which is the parent company of the MG Motor has already secured the deal from Fiat for the supply of the engines. Reportedly, the manufacturer also approached other engine suppliers in India but settled with Fiat. MG Motor will use a 1.5-litre or 1.8-litre petrol engine that is being developed in-house. But it has not been finalised yet.
The 2.0-litre, four-cylinder, turbocharged diesel engine produces a maximum power of 171 Bhp and peak torque of 350 Nm. Interestingly, both Maruti and Tata Motors have signed a contract with Fiat for the supply of the 2.0-litre Multijet engine. The same engine is expected to power the Maruti Vitara and Tata H5X in the future. Fiat and MG Motors are yet to make any formal announcement about the engine supply.
SIAC Motor Corporation is China's largest automobile manufacturer and is also GM's partner in China. The brand owns UK-based MG Motors and will launch the same in India next year.
The MG ZS will take on the likes of Hyundai Creta in the Indian market. However, the ZS in its current form is significantly larger than the Hyundai Creta and Renault Duster. Length-wise it is same as the Mahindra XUV 500 but has only 5-seats inside. It is not confirmed if MG Motors will bring in the exact same model or will tweak it for the Indian market. The brand plans to launch its first product in 2019 and one car each year after that. The company is also planning to launch electric vehicles in the Indian market.

"PhonoSys: Mobile Phonocardiography Diagnostic System for Newborns" by Amir Mohammad Amiri, Giuliano Armano et al.
Heart murmurs have been found to be a life threatening condition for the newborns who are born with cardiac abnormalities. The first sign of pathological changes of heart valves appears in phonocardiogram which contains very useful information about cardiovascular system. It is a challenging venture to distinguish pathological murmurs from innocent ones. In this paper we have developed a diagnostic algorithm called PhonoSys to analyze PCG using random forest. PhonoSys algorithm will run on mobile devices for remote PCG analysis. We recorded PCG signals from 120 newborns who are either healthy or with cardiac abnormalities. Eventually, in this study, 97.6% accuracy, 96.8% sensitivity, and 98.4% specicity were obtained to classify between innocent and pathological murmurs.


I founded creative spaces to express my love for excellence in design and workmanship. My 30-plus years in construction and remodeling provide the foundation needed to create living areas that inspire excitement, enthusiasm and enhance your quality of life. My passion is to take your space and transform it into something extraordinary.
The original project was to design and build a new double sided Propane fireplace between the living room and an open kitchen/family room space. The project then expanded to include overseeing and managing the updating of kitchen floor, counters, sinks, faucets and backsplashes (in both kitchen and bar area), adding a gas insert in the existing lower level fireplace, which in theory necessitated replacing a downstairs bathroom vanity, sink and faucet and then also repairing the exterior stair railing and small section of exterior cedar siding. Minor carpentry services were also required for installation of new kitchen appliances.
Overall, we are very pleased with the quality of the work on our construction project. The only reason we wouldn't give all As is because the project extended longer than anticipated, from the original two weeks to a month estimate to a full three months. Another frustration was the occasional lack of direct on-site supervision of or adequate communication with subcontractors (kitchen floor demo, counter island bracing, and Propane piping installation, in particular), which ultimately resulted in additional cost to us. In fairness, the extended time was in part due to the fact that the fireplace stoves took longer between ordering and arriving than anticipated. This delay forced Creative Spaces to reassign the construction crew elsewhere, and we then had to fit into new openings in the carpenters' schedules. The team had completed the design and demolition processes in a very timely fashion, but then the break in the schedule due to the stove delivery left us with a major delay in reconstruction and without a working kitchen for a full extra month. Probably another factor extending the time-frame was due to our adding pieces to Creative Space management and oversight responsibilities, but which we did thinking it would facilitate and expedite coordination of the project. While our project manager couldn't have been nicer or more well-intentioned, he, unfortunately, was spread very thin between client projects and was not able to be present when certain key subs were working on our project. In two cases, this definitely resulted in additional work having to be done at our expense (additional kitchen floor demo, bracing of counters and tiling of mantel), and the downstairs vanity replacement in the end was totally unnecessary. This oversight situation was addressed towards the very end of our project through the hiring of additional Creative Spaces staff and the company did split the additional floor demo cost with us. Ultimately, as we said before, we are very happy with the results. Again, the scheduling and the over-extension of our project manager were the only drawbacks. We were very pleased with everyone we dealt with at the company; they were all very professional and skilled. Yes, we would probably hire them again.

My funny story is when Santa put himself on the naughty list. I travelled the Mcr My Chemical Romance Official 2022 tour Tramp Stamp photo shirt home from work a few years ago, and I enjoyed all the Christmas lights and decorations every night. One house had a huge blow up Santa on top of the garage, with his arm raised, waving at you when the wind blew. One day I left work early, and it was still daylight. As I turned the corner on this windy day, I saw Santa was a bit deflated. He was slightly bent over and his arm had fallen down so that his hand was between his legs, and the wind was blowing a bit, and he was gently bobbing up and down, up and down, and he seemed to be enjoying himself entirely too much! I was crying with laughter, and I can never look at Santa again without flashbacks.

But it wasn't for a Mcr My Chemical Romance Official 2022 tour Tramp Stamp photo shirt of trying (except when he was on the Yankees). My nod goes to Jim Brown as he dominated in everything he did. Deion was great, but he was more interested in putting on a show or being a hot dog than he was a team player.

The Chrysler Corporation has always been the weakest of the Big 3 US auto makers, and Mcr My Chemical Romance Official 2022 tour Tramp Stamp photo shirt as another Quora discussion noted, Chrysler's ability to remain financially viable has been questioned every decade or so from its dawn in 1925 to today as the firm would swing from success to near bankruptcy. In the late 1970s, Chrysler ran into financial difficulties (again) with a portfolio overly reliant on large, gas-guzzling cars; in 1979, the Chrysler Corporation was bailed out by the US government with a $1.5 billion loan, and the company restructured operations to become financially viable by having its major brands – Chrysler, Dodge, and Plymouth – share automobile platform designs. Chrysler brand was the top of the line, and that brand retained a few unique designs not found in the other brands. Dodge was the mainstream brand, while Plymouth became the entry-price brand, simply badge-engineering Dodge or Mitsubishi designs with minimal value-add features. (Ram trucks remained uniquely Dodge products, and the Jeep brand, the remnant of acquiring AMC Motors, focused on SUV designs. AMC's Eagle brand did not last long either.). The 1980s and 1990s designs, especially K-cars and minivans, helped the Chrysler Corporation regain profitability, but buyers would frequently look at both Plymouth and Dodge offerings at the same time.
In the United States, state capitals aren't generally the Mcr My Chemical Romance Official 2022 tour Tramp Stamp photo shirt or most populated cities. Take as an example California (Sacramento is the capital, not Los Angeles or San Francisco) or Illinois (Springfield is the capital, not Chicago) and you could go on with Texas, Florida, etc… even when it comes to the United States as a whole you would think New York City or Los Angeles should be the capital and not Washington D.C, but it goes deeper than that, the United States is not centralized in one city like it happens to France/Paris, UK/London, Germany/Berlin and so on. As to why New York City is considered the capital of the world, it has been called that for the past 60 years. It is the home of the United Nations, Wall Street, New York Stock Exchange, lots of billionaires, people from all over the world live in the city. It's basically the financial powerhouse of the world although London has been following closely for the past few years. Other reasons to consider New York the capital of world would be fashion, music, entertainment, tourism, etc.
