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).
