我一直在尝试使用scons和SDL从源代码编译The Powder Toy（用C ++编写）。我承认我对编译/构建不是很有经验，但这看起来应该是可能的。
我在Mac OSX 10.9（Mavericks）上运行;这导致了SDL的问题。但是，我找到了一个解决方案，我现在已经成功安装了XCode，XQuartz，命令行工具，scons和SDL。但是，如果我cd进入源目录并运行scons --macosx --release --sse2 --nofft
我收到了错误
src/PowderToySDL.cpp:6:10: fatal error:
'SDL.h' file not found #include "SDL.h"
^
很明显，找不到包含SDL.h（./SDL/include）的文件夹。我尝试添加标签
--sdl-dir="~/Desktop/Programming/SDL-1.2.15/include"
对scons,的调用，但同样的错误仍然存在。我检查了目录./SDL/include，所有正确的文件都在那里;然而，scons似乎没有引用它们。
