owen LM-17 ~/Gimp-GIT/libmypaint $ cat libmypaint-gegl.pc

Name: libmypaint-gegl
Description: MyPaint brush engine library, with GEGL integration
Version: 1.1
Requires: gegl-0.3 libmypaint
Cflags: -I${includedir}/libmypaint-gegl
Libs: -L${libdir} -lmypaint-gegl

Hmm, there are already similar files for babl/GEGL/GIMP. So that file 
probably should be generated automatically when building/installing 
libmypaint, but there isn't one in the prefix. Did you create that file? 
or was it generated automatically?

I searched my history for libmypaint as well as otherthings found I did this;

a.  git clone
b.  I then read the
c.  Had to install scons
d.  The last scons command was # scons prefix=/home/owen/Gimp-GIT enable_gegl=true
(but judging by the number of other attempts, I must have had some problem)
e.  That generated the libmypaint-gegl.pc
f.  then I exported /home/owen/Gimp-GIT/libmypaint to the PKG_CONFIG path
g.  Lastly I installed MyPaint from a debian package manager for the brushes
h.  rebuilt gimp, there was an entry to load mypaint brushes, but "it didn't work"

All that was some time ago and many iterations later I see I no longer build gimp with libmypaint.

In the, there is an interesting line that says;

You can also build a minimal version of libmypaint directly into your application by including "libmypaint.c"

I never psyched that out, but would like to know how to do that.
