    This file is based on the instaling information and give an improved description on compiling and using your own OSMesa/GLU library in a supercomputer environment (running on supercomputers) which do not have Basilisk installed.

    Standalone installation

    The libraries are independent from Basilisk and can be installed separately. This can be done easily using something like:

    On the local system:

    cd $BASILISK
    tar czvf gl.tgz gl
    scp gl.tgz login@supercomputer.org:

    On the remote machine:

    tar xzvf gl.tgz
    cd gl
    make clean

    Installing OSMesa/GLU from source on a supercomputer

    If pre-compiled packages for OSMesa/GLU are not available (or broken) on the system you want to use, it is reasonably simple to install these libraries directly from source. Something like the following recipe should work on most UNIX systems:

    wget http://basilisk.fr/src/gl/mesa-17.2.4.tar.gz
    tar xzvf mesa-17.2.4.tar.gz
    cd mesa-17.2.4
    ./configure --prefix=/home/login/local --enable-osmesa \
                --with-gallium-drivers=swrast                \
                --disable-driglx-direct --disable-dri --disable-gbm --disable-egl
    make
    make install
    
    wget http://basilisk.fr/src/gl/glu-9.0.0.tar.gz
    tar xzvf glu-9.0.0.tar.gz
    cd glu-9.0.0
    ./configure --prefix=/home/login/local 
    make
    make install

    Then supposing that you have copy $BASILISK/gl in /home/login/local (installation instructions above) on the supercomputer :

    cd gl
    CFLAGS+='-I/home/login/local/include' make libglutils.a libfb_osmesa.a

    After that gl/ is compiled, and you want to compile a code you will need to specify the library paths by specifying these lines on your compilation script:

    MESA=/home/login/local/
    GL=/home/login/local/
    
    mpicc -Wall -std=c99 -O2 _$NAME.c -o $NAME    \
        -L$MESA/lib -I$GL -L$GL/gl \
        -lglutils -lfb_osmesa -lOSMesa -lGLU -lm

    And finaly to run your code you will need to specify the library paths by specifying these lines on your run script before the execution of the code:

    # export mesa libraries
    export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/linkhome/rech/genija01/ufo72gr/local/lib

    OSMesa/GLU on Occigen

    If you have an account on Occigen and you have installed OSMesa/GLU from source following the instruction above you can use something like:

    module purge
    module load openmpi
    module load intel
    module load llvm

    MESA=/home/login/local/
    GL=/home/login/local/
    
    # compilation of the code
    mpicc -Wall -std=c99 -O2 _$NAME.c -o $NAME    \
        -L$MESA/lib -I$GL -L$GL/gl \
        -lglutils -lfb_osmesa -lOSMesa -lGLU -lm
    
    # export mesa libraries
    export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/login/local/lib
    
    # execution of the code
    srun --mpi=pmi2 -K1 --resv-ports -n $SLURM_NTASKS ./$NAME \
