在OS X 10.7上构建SDL2：“ranlib：file：...没有符号”

Question

在狮子身上构建SDL2时，我在运行makefile时会遇到以下情况：

/usr/bin/ranlib: file: build/.libs/libSDL2.a(SDL_audiodev.o) has no symbols

ranlib: file: build/.libs/libSDL2.a(SDL_stdlib.o) has no symbols
ranlib: file: build/.libs/libSDL2.a(SDL_x11opengles.o) has no symbols

我不知道这是否与此有关，但之前我不得不do this fix停止抱怨SDL_x11sym.h:106:1。

好的，这就是我的所作所为：

1. 在终端中运行$ ./autogen.sh。

2. 在Xcode中打开./Xcode/SDL/SDL.xcodeproj。

3. 运行Framework目标：

   

4. 在finder中打开生成的框架：

   

5. 将SDL2.framework复制到/Library/Frameworks/：
