Installation of gegl

If you are installing over a previous version of gegl, one of the modules will need to be removed. As the root user, run the following command to remove it:

rm -f /usr/lib/gegl-0.4/vector-fill.so

Install gegl by running the following commands:

mkdir build &&
cd    build &&

meson setup --prefix=/usr --buildtype=release -D libav=disabled .. &&
ninja

To run the tests, issue: ninja test.

Now, as the root user:

ninja install

Command Explanations

-D libav=disabled: This switch disables building support for ffmpeg because the latest version causes the build to fail.

-D docs=true: Use this switch to build and install the documentation (requires GTK-Doc-1.34.0).
