我试图用SDL2编译SDL_mixer 2，从中 check out 了最新代码:
http://hg.libsdl.org/SDL_mixer
也可以毫无问题地编译SDL2和SDL_image。

编译SDL_mixer时收到编译错误:

最佳答案

我认为您可以删除MP3_MUSIC预处理程序宏，或者在搜索路径中包含smpeg。

关于c++ - 使用Visual Studio Express和SDL2在Windows中破坏了SDL_mixer 2编译，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10229508/
