I'm doing some tutorials on OpenGL that use FreeGLUT.
Apparently this is how you build and install it on the mac:
CPPFLAGS="-I/usr/X11R6/include" ./configure --prefix="${PWD}/../"
make
make install
Unfortunately this on its own gives me an error when I do the make
command: Undefined symbols for architecture x86_64
After doing abit of work I've found that an improvement on the first line is:
CPPFLAGS="-I/usr/X11R6/include -L/usr/X11R6/lib" LDFLAGS="-L/usr/X11R6/lib" ./configure --prefix="${PWD}/../"
Unfortunately when I do the make
command I'm still getting an error:

This has been documented on the net before, but the solution isn't really all that helpful in this instance. I've also tried swapping it for the GLUT.framwork that comes with OS X, but the examples are using FreeGLUT-specific functions.
CPPFLAGS="-I/usr/X11R6/include -L/usr/X11R6/lib" ./configure --prefix="${PWD}/../"
gets rid of the 'Undefined symbols' error. But now I getld: library not found for -lGL
\collect2: ld returned 1 exit status
