Hi there I was wondering if anyone could help me with a linking problem I am having with Visual Studio 2005. I want to link a static lib file to a CLR DLL (managed C++). I have built Crypto++ v5.4 as a static library and I have a managed wrapper class in a DLL. The linker error I get is: LIBCMTD.lib(crt0.obj) : error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup How do I define this function or do I need to set an alternative DLL entry point? I suspect some of the problem might be that the Crypto++ lib file is built with non-Unicode libraries and the managed classes DLL uses Unicode by default. If this is the case, how do I force the non-Unicode CRT to initialize? Many thanks Mark
