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
