How to debug application when third-party library provides no debug build?

I have an application I'm working on that uses two third party libraries, each with pre-compiled libs and dlls, one of开发者_StackOverflow中文版 which provides necessary .lib files for both debug and release builds (A[d].lib) and the other which provides only .lib files for release builds (B.lib).

Compiling in Release mode (using MSVC9) works fine, however attempting to compile in debug mode fails because third party A requires LIBCMTD.lib (or MSVCRTD.lib) while third party B requires LIBCMT.lib (or MSVCRT.lib).

Can I work around this or am I stuck debugging in release mode?

Do you want full debug mode, or do you just want to be able to debug? If the later is the case, just go to the linker options, and turn on the generation of symbolic information (.pdb). This way you can use the debugger in your own code, step through the lines, and look at variables. If you get annoyed by the changes in control flow that the optimizers create, you can go to the compiler options, and turn off optimizations. This way you get to use the debugger AND build in release mode. Once you're happy with your code, you just change the settings back to creating optimized code.

Try passing /NODEFAULTLIB:LIBCMT to the linker.

I am not sure it can be done directly with static libraries. I suggest you package library B into a dynamic library, then use this new B' library. Your problems will have disappeared.
