You're right by assuming that main now gets redefined everywhere ...
howver, in SDMain.m, there is the following sequence:

#ifdef main
#  undef main

That _should_ remove the definition in this file ... I wonder what's
going wrong here?
Could you maybe try to replace the "-Dmain=SDL_main" in CMakeLists.txt
with "-DSDL_MAIN_NEEDED=1" instead? Then the header SDL_main.h of the
libSDL should take care of the renaming... maybe that works better?

Ok, thanks, good to know.
