User Notes:

Installation of gegl

If installing over a previous version of gegl, one module needs to be removed. As the root user, run:

rm -f /usr/lib/gegl-0.4/

If LibRaw-0.21.0 or above is installed, the build fails due to a change in the ABI. Fix the issue by issuing:

sed -e '/shot_select/s/params/raw&/' \
    -i operations/external/raw-load.c

Install gegl by running the following commands:

mkdir build &&
cd    build &&

meson --prefix=/usr --buildtype=release .. &&

To run the tests, issue: ninja test. This should indicate no failures, but will skip many tests depending on optional dependencies installed on the system.

Now, as the root user:

ninja install
