是否可以在Mac OS X上构建FreeGLUT？

Question

我正在做一些使用FreeGLUT的OpenGL教程.

显然,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,这本身就会给我一个错误:Undefined symbols for architecture x86_64

做完工作后,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:

这已经在网上记录过了,但是在这个例子中解决方案并没有真正有用.我也尝试将其交换为OS X附带的GLUT.framwork,但这些示例使用的是FreeGLUT特定的函数.

XQuartz 2.7.2 替换为 FreeGLUT (2.8.0)，而不是旧的 MesaGLUT。因此，只要您有 OS X 10.6.3 或更高版本，您就可以安装 XQuartz 2.7.2 或更高版本。看：
