Question

我试图从源代码构建eduke32。

除其他外，它需要SDL_mixer.h。

我确实拥有它：

$ locate SDL_mixer.h
/usr/include/SDL/SDL_mixer.h

（我安装了Devel Tools组，以及许多其他开发包）

但是当我开始构建时，我发现SDL_mixer文件找不到错误。

$ make

即使我添加了include-dir选项，也会发生这种情况：

$ make --include-dir=/usr/include/SDL/

这里发生了什么？有人有线索吗？

Answer 1

我检查了Makefile，发现该程序正在寻找SDL ** 2 ** / SDL_mixer.h

我安装了SDL2_mixer-devel软件包，一切都很顺利。

我在make中使用--include-dir选项似乎与我试图做的事情无关。（见etan评论）

make无法找到SDL_mixer.h，但我包含了SDL目录
