[Freeglut-developer] Setting Up FreeGlut on a Mac with Eclipse CDT

[Jon K. <jon...@gm...>]

Hi All,

I'm having a heck of a time trying to get FreeGlut up and running on my Mac
using Eclipse CDT and I was hoping I could get some help.

I downloaded the tar for 2.6.0 and had to follow the instructions here in
order for it to properly extract and make without errors.

tar -xzf freeglut-2.6.0.tar.gz
cd freeglut-2.6.0
./autogen.sh
CPPFLAGS="-I/usr/X11R6/include" ./configure --prefix="${PWD}/../"
make
make install

This created two directories, once called include and one called lib. In the
include there is the GL folder with freeglut_ext.h, freeglut_std.h,
freeglut.h and glut.h. In the lib folder there is libglut.3.dylib,
libglut.a, libglut.dylib and libglut.la.

So naturally in Eclipse I pointed the include directory to the include
folder and added the lib folder to library paths.

This allowed me to include freeglut.h properly but when i went to build it
would error since it couldn't find GL/gl.h and GL/glu.h.

Since I'm on a mac, those files are part of the OpenGL framework on the OS
so i modified the freeglut_std.h so it reads:

#if defined(__APPLE__)
#include <OpenGL/gl.h>
#include <OpenGL/glu.h>
#else
#include <GL/gl.h>
#include <GL/glu.h>
#endif

This fixed the include build error but now I have the following errors which
seems like the linker is not finding the libraries properly. Can anyone help
me out with what to do next?
