I am trying to build boost using the win32 port of pthreads. The command I use is: bjam -STOOLS=vc-7_1 -sPTW32_DIR="where-i-put-win32-pthreads" -sPTW32_LIB="pthreadVC.lib" stage The error I get is: LINK : warning LNK4001: no object files specified; libraries used LINK : warning LNK4068: /MACHINE not specified; defaulting to X86 LINK : fatal error LNK1561: entry point must be defined Would be nice of Mico$oft said ***which*** entrypoint is missing. Without that little snippet of information I can only guess.... The log shows the linker command line used: CALL "C:\Program Files\Microsoft Visual Studio .NET 2003\VC7\bin\VCVARS32.BAT" >nul "C:\Program Files\Microsoft Visual Studio .NET 2003\VC7\bin\link" /nologo /INCREMENTAL:NO /LIBPATH:e:\work\overnight\win_extern\lib" /DEBUG /DLL /subsystem:console /out:"..\..\..\bin\boost\libs\regex\build\boost_regex.dll\vc-7_1\debug\t hreading-multi\ boost_regex-vc71-mt-gd-1_33_1.dll" /IMPLIB:"..\..\..\bin\boost\libs\regex\build\boost_regex.dll\vc-7_1\debu g\threading-multi\ boost_regex-vc71-mt-gd-1_33_1.lib" @"..\..\..\bin\boost\libs\regex\build\boost_regex.dll\vc-7_1\debug\threa ding-multi\ boost_regex-vc71-mt-gd-1_33_1.CMD" The CMD file just contains a list of the object files. Any ideas please? I am tearing my hair out here. A quick google reveals that a few other people across the world also have this problem, but not many. Those people posted their question to various forums and unfortunately got no reply :-( Regards, Andrew Marlow ---- There is an emerald here the size of a plover's egg!
