Hi, As reported in the fediverse, sdl2 generates SIGILL on Mac G3s [0].
sdl2 is built with AltiVec support, runtime detection is present and valid (see $WRKSRC/src/cpuinfo/SDL_cpuinfo.c), yet failing. So the simple solution is to remove AltiVec from the build for now. I've tested this on my PowerBook G4 against ffplay, mpv, openttd and scummvm, without issues. I've also tested successfully these ports on my Mac Mini G4, but this time, using a kernel without the ALTIVEC option. OK? Charlène.
