我想在Ubuntu上为Android编译SDL2.
我使用./configure配置SDL2 --host = arm-linux-androideabi
在使用ndk-build进行编译之后,我得到了一系列未定义的引用:
Compile thumb : SDL2-2.0.0 <= SDL_androidkeyboard.c
Compile thumb : SDL2-2.0.0 <= SDL_androidtouch.c
Compile thumb : SDL2-2.0.0 <= SDL_androidvideo.c
Compile thumb : SDL2-2.0.0 <= SDL_androidwindow.c
SharedLibrary : libSDL2-2.0.0.so
