[Gimp-developer] building GIMP from git

[Olivier <olecarme gmail com>]

Hello all.

I'm trying to build GIMP-2.9 as explained on
http://www.gimp.org/source/howtos/gimp-git-build.html. I'm using Ubuntu
15.04.

Everything seems to work smootly, but when I try using gimp-2.9 I get the
error message:

GEGL operation missing!

GIMP requires the GEGL operation "gegl:maze".
This operation cannot be found. Check your
GEGL install and ensure it has been compiled
with any dependencies required for GIMP.

​What am I doing wrong?​ When I build GEGL, the only warnings I get after
configuring it are that the Vala support is missing, as well as avformat
amd umfpack.

Thanks for any help.
