I have built boost python. I am trying to use the boost_1_74_0\libs\python\example\tutorial example. I keep getting a fail in the build of the dll: msvc.link.dll bin\msvc-14.0\debug\boost_python.dll LINK : warning LNK4001: no object files specified; libraries used LINK : error LNK2001: unresolved external symbol __DllMainCRTStartup@12 bin\msvc-14.0\debug\boost_python.dll : fatal error LNK1120: 1 unresolved externals call "bin\standalone\msvc\msvc-14.0\msvc-setup.bat" x86 >nul link /NOLOGO /INCREMENTAL:NO /DLL /DEBUG /MACHINE:X86 /MANIFEST:EMBED /subsystem:console /out:"bin\msvc-14.0\debug\boost_python.dll" /IMPLIB:"bin\msvc-14.0\debug\boost_python.lib" @"bin\msvc-14.0\debug\boost_python.dll.rsp" Any advice as to what might be wrong. My Visual Studio 2019 does not have the corelibc.lib. I only find that under 'WinCE' libs, and so not found when I compile msvc 14... thanks
