macos - 在 OS X 10.7 上构建 SDL2：“ranlib：文件：……没有符号”

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

我不知道这是否与它有关，但以前我必须进行此修复以阻止它抱怨SDL_x11sym.h:106:1.

好的，这就是我所做的：

1. $ ./autogen.sh在终端中运行。

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

3. 运行Framework目标：

   

4. 在 finder 中打开生成的框架：

   

5. 复制SDL2.framework到/Library/Frameworks/：
