My small projects involving OpenGL

Installing Mesa on Linux

An open source equivalent to OpenGL.

See mesa3d.org/install

Fedora Core 4 or RedHat required the X development package.

make linux-x86
  As root 
make install

Previously it was a little harder or I was just doing weird stuff.

Downloaded MesaDemos-5.0.tar.gz and MesaLib-5.0.tar.gz .

As root, copy MesaDemos-<>.tar to /usr/local and expand.
Then copy MesaLib-<>.tar to /usr/local and expand. Then in Mesa<> ./configure then ./make

After the build find the library files.
find . -name \*.so
./src/OSmesa/.libs/libOSMesa.so
./src/.libs/libGL.so
./si-glu/.libs/libGLU.so
./src-glut/.libs/libglut.so

Copied to /usr/lib/ except for libglut.so as the glut lib depended on other crap. So inside ./src-glut/.libs/
cp -d libg* /usr/lib/

For some reason you need to download the MesaDemos to compile glut! Sanity???

Using the libraries code is fairly straight forward. When compiling OpenGL and Glut -lGLU -lGL -lglut -L/usr/lib -I/usr/include/GL .
