我正在使用some tutorials on OpenGL FreeGLUT。
Apparently这是你在mac上构建和安装它的方式：
CPPFLAGS="-I/usr/X11R6/include" ./configure --prefix="${PWD}/../"
make
make install
不幸的是，当我执行make命令时，这本身就给我一个错误：Undefined symbols for architecture x86_64
在完成工作后，我发现第一行的改进是：
CPPFLAGS="-I/usr/X11R6/include -L/usr/X11R6/lib" LDFLAGS="-L/usr/X11R6/lib" ./configure --prefix="${PWD}/../"
不幸的是，当我执行make命令时，我仍然收到错误：

这是documented on the net before，但解决方案在这个实例中并没有那么有用。我也尝试将其交换为OS X附带的GLUT.framwork，但这些示例使用了FreeGLUT特定的函数。

It was suggested，freeglut演示错误地宣告那些PFN * PROC两次。
因此，通过简单地从smooth_opengl3.c中注释掉那些双重定义，免费过剩将通过编译阶段。但是，根据我的经验，它不会运行并给出一些关于GLSL的错误。
Mac OS X上也提出了GLUT framework should be used。

XQuartz 2.7.2交换到FreeGLUT（2.8.0）而不是旧的MesaGLUT。因此，如果你有OS X版本10.6.3或更高版本，你可以安装XQuartz 2.7.2或更高版本。见：

我可以使用以下参数进行配置：
./configure CFLAGS="-I/usr/X11/include/X11/extensions -L/usr/X11/lib" LIBS="-lXrandr -lXxf86vm -lXi" --with-x --x-includes=/usr/X11/include
