Error when statically building a windows application

Question

I have an application that compiles and works fine when I dynamically link everything, but when I want to have a static build of it, it will not compile.

In Visual Studio 2010, I set the "Use MFC in a Static Library" option.

When I do that, I get this error:

Error   1   error LNK2001: unresolved external symbol _wWinMain@16  LIBCMT.lib(wwincrt0.obj)

I have tried adding LIBCMT.lib as an additional library, but that doesn't change anything.

Any ideas on how to fix this problem?

Answer 1

From the message that it's missing WinMain that implies to me that some piece of your project is being built as an application and NOT as a library.

Try a full rebuild and ensure that all relevant options are set to build a static library. I believe libcmt.lib should only be linked to your final application, NOT to the library.
