Hi,
I try compile OpenXcom for Wii. It uses SDL lib.

I have these errors:

Hello,
as you said OpenXcom uses SDL, but uses also other modules of SDL
SDL (libsdl1.2)
SDL_mixer (libsdl-mixer1.2)
SDL_gfx (libsdl-gfx1.2), version 2.0.22 or later
SDL_image (libsdl-image1.2)

Do you have all of them in your env?

Hi, HudsonBr.
Yes, I added all libraries to makefile.
But I think that errors are due to wrong SDL_mixer archive: ModPlug_* functions seem added in SDL2, not in SDL1.2 but SDL_mixer.a (1.2.12) referred them.
As you can see, errors is related to undefined functions required by source music_modplug.c, in libSDL_mixer.a and not related to OpenXcom sources.

However, this is my Makefile. Can someone help me to found the error?
Thanks in advance.
