c++ - 使用 Visual Studio Express 和 SDL2 在 Windows 中破坏 SDL_mixer 2 编译

Question

我试图用 SDL2 编译 SDL_mixer 2 从：
http
://hg.libsdl.org/SDL_mixer 中检查了最新代码， SDL2 和 SDL_image 也没有问题编译。

编译 SDL_mixer 时出现编译错误：

有人知道吗？

Answer 1

Take a look at the PreProcessor Definitions.

Remove these

MOD_MUSIC
MOD_DYNAMIC=\"libmikmod-2.dll\"
OGG_MUSIC
OGG_DYNAMIC=\"libvorbisfile-3.dll\"
FLAC_MUSIC
FLAC_DYNAMIC=\"libFLAC-8.dll\"
MP3_MUSIC
MP3_DYNAMIC=\"smpeg.dll\"

If you want to use any of those file types in your audio, you need to get those .dll files as well. I would recommend compiling those libraries statically instead of dynamically to make thing more cross-platform compatible.

Answer 2

我认为您可以删除 MP3_MUSIC 预处理器宏或在搜索路径中包含 smpeg。
