title: Eclipse c++ with mingw comiler cant build boost regex example, can find .a library files
body: <p>I'm trying to build the boost regex example in eclipse using mingw on vista.
  I built boost ok with mingw as there are library files XXXX.a.
  I could build/compile the first boost example that doesnt require any of the compiled boost libraries.</p>
  
  <p>When I compile the regex example I get a linker error saying it cant find the library file.
  I have tried various libray file names eg leave off the .a extension, leave off the lib prefix etc.</p>
  
  <p>Now the interesting thing is that if I leave off the library extension and rename the library file to XXX.lib it works and runs ok.</p>
  
  <p>So why cant it read the .a library file?</p>
  
  <p>It must be my setup somewhere but I dont know where or what to set.</p>
  
  <p>From what I read everyone is ok linking the .a file except me :(</p>
  
  <p>Thanks in advance,
  Kim</p>
