lbcmt.lib reports missing std::exception in VS 2005 prof.

Darko Miletic

Recently I wrote a dll in c++ and to simplify the distribution I decided
to link with multithreaded static library (/MT or /MTd option). In debug
everything works fine but in release I get this:

parseMetadata.obj : error LNK2001: unresolved external symbol "public:
__thiscall std::exception::exception(void)" (??0exception@std@@QAE@XZ)
2>libcpmt.lib(string.obj) : error LNK2001: unresolved external symbol

This does not make much sense to me? Is that a bug? Do I need service
pack or something else?

It sounds like the C++ runtime library (libcpmt.lib) wasn't linked for some
reason. Another possibility is that you have multiple versions of VC++
installed, and the linker is linking the wrong library.

You could try adding /verbose to your linker options to see exactly what's
going on in either case.

You where right. I did have multiple versions of libcpmt.lib and
compiler used the wrong one. Thank you for your help :)
