title: SoundTouch compilation with Xcode?
body: <p>I'm trying to compile SoundTouch Framework in my Xcode project,
  but I have no clue of what I'm doing to be honest.</p>
  
  <p>Does anyone have any instructions?</p>
  
  <p><strong>What I've done so far</strong></p>
  
  <p>Running <code>./bootstrap</code> gives me the following output</p>
  
  <pre><code>autoreconf: Entering directory `.'
  autoreconf: configure.ac: not using Gettext
  autoreconf: running: aclocal -I config/m4 --output=aclocal.m4t
  Can't exec "aclocal": No such file or directory at /usr/local/Cellar/autoconf/2.69/share/autoconf/Autom4te/FileUtils.pm line 326.
  autoreconf: failed to run aclocal: No such file or directory
  </code></pre>
  
  <p>If I recall correctly, there is no <code>autoreconf</code> for Mac OS, right?</p>
  
  <p>SoundTouch apparently requires at least <code>GCC 4.4</code> but Mac OS only has <code>GCC 4.3</code>, so I downloaded <code>GCC 7</code> from <code>homebrew</code>, but using it only with the command <code>gcc-7 ./bootstrap</code> gives me the following output</p>
  
  <pre><code>gcc-7 bootstrap
  ld: warning: ignoring file bootstrap, file was built for unsupported file format ( 0x23 0x20 0x24 0x49 0x64 0x3A 0x20 0x62 0x6F 0x6F 0x74 0x73 0x74 0x72 0x61 0x70 ) which is not the architecture being linked (x86_64): bootstrap
  Undefined symbols for architecture x86_64:
    "_main", referenced from:
       implicit entry/start for main executable
  ld: symbol(s) not found for architecture x86_64
  collect2: error: ld returned 1 exit status
  </code></pre>
  
  <p>How can I successfully compile SoundTouch?</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>I tried copying the essential files to one folder, add it to my project and compile.</p>
  
  <p>Now I get this error: </p>
  
  <pre><code>Undefined symbols for architecture x86_64:
    "soundtouch::SoundTouch::SoundTouch()", referenced from:
        MyAudioProcessor::MyAudioProcessor() in libMy.a(PluginProcessor.o)
  ld: symbol(s) not found for architecture x86_64
  clang: error: linker command failed with exit code 1 (use -v to see invocation)
  </code></pre>
  
  <p>Why is it saying that there are undefined symbols?</p>
