libsdl2-classic =============== This package provides the "classic" implementation of SDL 2 as a library in /usr/lib/${DEB_HOST_MULTIARCH}/sdl2-classic. You can force SDL 2 programs to use this by loading the library using SDL_DYNAMIC_API, for example: $ SDL_DYNAMIC_API='/usr/$LIB/sdl2-classic/libSDL2-2.0.so.0' \ openarena even on systems where sdl2-compat is the default (which can be achieved by installing the libsdl2-compat-shim package). Please see the README.Debian of the libsdl2-compat package for details of how to test sdl2-compat:
