User Notes:

Installation of gegl

At first, adjust some test scripts to use Python 3 installed in LFS, instead of EOL'ed Python 2:

sed '1s@python@&3@' -i tests/python/*.py

Install gegl by running the following commands:

mkdir build &&
cd    build &&

meson --prefix=/usr .. &&

To test the results, issue: ninja test.

Now, as the root user:

ninja install
