</div>you need to link against the boost-threads library. Under MSVC boost
uses auto-linking feature and specifies the libs to be linked via a
pragma directive in a header file of the lib. AFAIK GCC does not
support this, so you need to do it explicitly yourself using the -l
linker option.<br><br>Regards,<br>Ovanes<br>
