Here is almost a copy/paste of the instruction written by Quentin Magdelaine that you can find here to fix off-screen rendering bug using OSMesa after the recent libosmesa update on Debian10.1/19.0.2-1ubuntu1.1~18.04.1 distribution.

    Instructions. First, remove the new OSmesa library which does not work:

    sudo apt remove libosmesa6-dev

    Then download an older version:


    Then decompress it (change [username] for yours (ex: toto)):

    tar -zxvf mesa-18.2.8.tar.gz
    cd mesa-18.2.8
    ./configure --prefix=/home/[username]/local --enable-osmesa \
                --with-gallium-drivers=swrast                \
                --disable-driglx-direct --disable-dri --disable-gbm --disable-egl

    If it doesn’t find zlib, install zlib1g-dev with:

        sudo apt install zlib1g-dev

    Try again. If it still doesn’t work instak pkg-config:

    sudo apt install pkg-config
    and try again, it should work.

    Compile the library:


    (This step is quite long.) And install it:

    make install

    The library is not installed in the standard path (/usr/lib/), so you need to tell gcc and basilisk about it. First, enter in your terminal:

    export LD_LIBRARY_PATH=/home/[username]/local/lib:$LD_LIBRARY_PATH

    and, to not have to do it again as soon as you open a new terminal:

    echo "export LD_LIBRARY_PATH=/home/[username]/local/lib:$LD_LIBRARY_PATH" >> ~/.bashrc

    Then in the config file in basilisk/src/, change the line

    OPENGLIBS = -lfb_osmesa -lGLU -lOSMesa
    OPENGLIBS = -L/home/[username]/local/lib -lfb_osmesa -lGLU -lOSMesa

    And in fb_osmesa.c in basilisk/src/gl/, change the line

    #include <GL/osmesa.h>
    #include </home/[username]/local/include/GL/osmesa.h>

    You can now compile the libraries provided by basilisk in basilisk/src/gl:

    make libglutils.a libfb_osmesa.a

    and the bview-servers in basilisk/src/:

    make bview-servers

    You should be able to compile and run successfully all your codes using the standar Makefile of Basilisk. Here is a test of the Bview functionnalities.

    cp $BASILISK/test/view.c .
    make view.tst

    Or if you do not use makefile, you have to use the following compilation line:

    qcc view.c -lm -L/home/[username]/local/lib/ -L$BASILISK/gl/ -lOSMesa -lglutils -lfb_osmesa -lGLU

    Note that you may experienced some trouble to play with vlc .mp4 videos generated with this fix. A quick fix to this is to use cvlc.
