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/vector-fill.so
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 .. &&
ninja
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
