3.6. Install GLUT 3.7 Distribution (optional)

If you installed the MesaDemos/MesaLib package, then you have already installed GLUT 3.7 since it is included with MesaDemos. However, you may be interested in installing the GLUT manpages and you can skip right to the "Install GLUT manual pages", below ...

Installing GLUT is a bit tricky. I'm not too familiar with imake, the program that it uses to manage the Makefiles, and didn't quite see how to get GLUT to install to where I wanted it (/usr/lib, but MesaDemos will do this without any trouble though). It can be done manually anyhow:


  cd /usr/src
        tar -xvzf glut-3.7.tar.gz
        cd glut-3.7

        Read the file: README.linux
        cd linux
        READ the file: README
        cp Glut.cf ..
        cd ..
        Edit Glut.cf: remove any Mesa references.
        Replace any -lMesaGL -lMesaGLU with -lGL -lGLU if needed.
        In particular, replace:
                OPENGL = $(TOP)/../lib/libMesaGL.so
                GLU = $(TOP)/../lib/libMesaGLU.so
        with:
                OPENGL = -lGL
                GLU = -lGLU

        ./mkmkfiles.imake
        cd lib/glut
        cp /usr/src/glut-3.7/linux/Makefile .
        Edit the Makefile: remove any Mesa references.
        Replace any -lMesaGL -lMesaGLU with -lGL -lGLU if needed.
        In particular, replace:
                OPENGL = $(TOP)/../lib/libMesaGL.so
                GLU = $(TOP)/../lib/libMesaGLU.so
        with:
                OPENGL = -lGL
                GLU = -lGLU

        make
        ln -s libglut.so.3.7 libglut.so
        ln -s libglut.so.3.7 libglut.so.3
        cp -d libglut.* /usr/lib
        cd ..
        cd gle
        # make a shared lib for libgle
        make
        gcc -shared -o libgle.so.3.7 *.o
        ln -s libgle.so.3.7 libgle.so
        ln -s libgle.so.3.7 libgle.so.3
        cp -d libgle.* /usr/lib
        cd ..
        cd mui
        # make a shared lib for libmui
        make
        gcc -shared -o libmui.so.3.7 *.o
        ln -s libmui.so.3.7 libmui.so
        ln -s libmui.so.3.7 libmui.so.3
        cp -d libmui.* /usr/lib

        # Install the GLUT manual pages (not included with MesaDemos)
        cd /usr/src/glut-3.7
        make SUBDIRS=man Makefile
        cd man/glut
        make install.man
        ldconfig

        cd ../../progs/demos/ideas
        # edit the Makefile, change OPENGL = -lGL and GLU = -lGLU
        make
        ./ideas
        # test compiling some demos
        # take a look at which libraries have to be linked (-lX11 ...) in
        # the Makefiles.  Qt's tmake program available at www.troll.no
        # is a quick way to make a Makefile but you have to edit it
        # and add the -l needed.
