使用SCON在Mac OSX 10.9上构建
Using scons to build on Mac OSX 10.9
我一直在尝试使用scons和SDL从源代码中编译粉末玩具（用C 编写）。我承认我在编译/建筑物方面不是很有经验，但这看起来应该是可能的。
我在Mac OSX 10.9（Mavericks）上运行；这引起了SDL问题。但是，我找到了一个修复程序，现在我成功安装了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
我得到错误
src/PowderToySDL.cpp:6:10: fatal error:
'SDL.h' file not found #include "SDL.h"
^
很清楚，未找到包括sdl.h（./sdl/include）的文件夹。我尝试添加标签
--sdl-dir="~/Desktop/Programming/SDL-1.2.15/include"
呼叫scons,，但是相同的错误持续存在。我检查了目录./SDL/include，所有正确的文件都在那里。但是，SCONS似乎并没有引用它们。
完整输出：
