C++ Question

Receiving undefined references to various Windows libraries when compiling with SDL 2 and -static?

I'm working on a modification of the Wolfenstein 3D engine in SDL2 (using Wolf4SDL as a base) and I've run into a problem - when using -static in the linker options, I get a large variety of undefined references to various things. Here's my build log to show what I mean:

This does not happen when linking a normal Wolf4SDL mod (which uses SDL 1.2), and it links correctly if I don't use -static but then won't run without various other DLLs being present (namely libgcc_s_dw2-1.dll and the like). While I can just change PATH to include my MinGW directory, when it comes time to distribute it I can't expect everyone to have MinGW installed, and I want to keep the number of DLLs I'm distributing with my mod to a minimum considering I'm already using SDL_mixer and SDL_image which come with a ton of DLLs already. Anyone have a solution to this?

Answer

OK, fixed the problem - I needed to link a variety of Windows libraries, namely Ole32, Oleaut32, Imm32, Winmm and Version. Not sure why this wasn't the case for SDL 1; it wasn't mentioned in the Migration Guide either so I'm not sure where the difference comes from.
