Linking boost static regex pulling in msvcprt

votes

I'm compiling my app /MT and linking against the boost -mt-s libraries (multithreaded static), but the boost regex library (version 1.45) seems to be pulling in the /MD msvcrt.lib, which causes linker errors.

I can workaround the problem using /NODEFAULTLIB:msvcrt.lib, but I'd much rather fix it. It it a known bug in boost or am doing something stupid?

Relevant linker (/VERBOSE:lib) output:

Searching /boost/stage/lib\libboost_regex-vc100-mt-s-1_45.lib: Searching C:\Program Files\Microsoft Visual Studio 10.0\VC\LIB\msvcprt.lib:

Finished searching libraries LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library

I am generally a C#/Dot Net developer, but now have a native windows C++ project which has to link to static Boost libraries. While I would prefer to use dll's/assemblies throughout the application (safety related) dictates otherwise.

I too am using Visual Studio 2010 and initially struggled to link to the static boost libraries. I found the only way to do this was to create a new Win 32 static library to interoperate with the Boost library.

The short answer is not to use multithreaded static configs, ever. Newer versions of Visual Studio don't even allows this as an option.
