title: A short c++ file and makefile: I can make in the shell, but get lots of error while building it in the Eclipse
body: <p>I'm compiling a very short c++ file using makefile.The c++ file using a external libary named ClanLib, but that's not the point, because I can use "make" command to  compile it in the shell, so the c++ file and the makefile are OK.</p>
  
  <pre><code>#include &lt;ClanLib/core.h&gt;
  #include &lt;ClanLib/application.h&gt;
  
  class ConsoleProgram {
  public:
      static int main(const std::vector&lt;CL_String&gt; &amp;args);
  };
  CL_ClanApplication app(&amp;ConsoleProgram::main);
  int ConsoleProgram::main(const std::vector&lt;CL_String&gt; &amp;args) {
      CL_SetupCore setup_core;
      CL_ConsoleWindow console_window("Console");
      CL_Console::write_line("Hello World!");
      CL_Console::wait_for_key();
      return 0;
  }
  
  
  
  
  BIN     = main
  OBJF    = main.o
  LIBS    = clanCore  clanDisplay  clanGL  clanGL1  clanApp clanSWRender
  VERSION = 2.3
  
  PACKAGES = $(patsubst %, %-$(VERSION), $(LIBS))
  INCLUDE += -I/usr/include/ClanLib-2.3/ 
  CXXFLAGS += $(INCLUDE) `pkg-config --cflags $(PACKAGES)` -pthread
  
  all: $(BIN)
  
  $(BIN): $(OBJF)
      $(CXX) $(CXXFLAGS) $(OBJF) -o $(BIN) `pkg-config --libs $(PACKAGES)`
  
  clean:
      find . -name '*.o' -type f -print -exec rm -rf {} \;
      rm -f $(BIN)
  
  %.o : %.cpp
      $(CXX) $(CXXFLAGS) -c $&lt; -o $@
  
  %.o : %.hpp
      $(CXX) $(CXXFLAGS) -c $&lt; -o $@

  <p>But I get lots of errors while compiling it in the eclipse, I've been googling from morning but without any clues.</p>
