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.

It sort of sounds like GIMP isn't finding a recent enough version of GEGL. Did you install babl from git and GEGL from git in the same prefix as GIMP from git?

In case they might be helpful, I put up some articles on building and updating GIMP from git:

Building GIMP for artists and photographers http://ninedegreesbelow.com/photography/build-gimp-in-prefix-for-artists.html

Updating GIMP for artists and photographers http://ninedegreesbelow.com/photography/update-gimp-in-prefix-for-artists.html

The second article also explains how to use the git log to see the latest updates.

Hmm, also, as shown in the first article, based on a discussion on this list awhile back, sometimes even when building in a prefix, GIMP looks in the wrong place unless you add a line about the GIO_EXTRA_MODULES, as per the following (your linux OS might need lib64 instead of lib);

PREFIX=$HOME/code/gimplch/install export PATH=$PREFIX/bin:$PATH
export LD_LIBRARY_PATH=$PREFIX/lib:$LD_LIBRARY_PATH export XDG_DATA_DIRS=$PREFIX/share:$XDG_DATA_DIRS export ACLOCAL_FLAGS="-I $PREFIX/share/aclocal" export PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig:$PKG_CONFIG_PATH export GIO_EXTRA_MODULES=/usr/lib/gio/modules export SRC_DIR=$HOME/code/gimplch/build

Thus GEGL and BABL are not built from git, and they are installed in the system directories, not under a special prefix. Your articles seem to suggest that I should have chosen the second solution, but http://www.gimp.org/source/howtos/gimp-git-build.html does not suggest that.

Since GEGL is installed in only one place, i.e. /usr/local/lib/, I don't understand where GIMP could find it in a wrong place.

Hello,

I had some surprises when building gimp (with gegl/babl from git too). First I tried to use babl and gegl provided by Debian testing, but they're not recent enough.
Then I uninstalled Debian packages and install the babl/gegl builds from root. I don't remember if it succeeded but anyway, it wasn't ok for Gimp. Hopefully, this link helped me a lot: http://wiki.gimp.org/wiki/Hacking:Building/Linux

It seems building process needs some "black magic" to make it easier :-)

Based on comments in https://aur.archlinux.org/packages/gegl-git/, it does look like maybe the original problem was that GIMP was finding a too-outdated version of GEGL.

I never needed to export GIO_EXTRA_MODULES until I tried to run GIMP 2.8 installed from the Gentoo package manager alongside babl/GEGL/GIMP from git installed in a prefix. But here's the reference, fwiw:

https://mail.gnome.org/archives/gimp-developer-list/2015-February/msg00042.html https://mail.gnome.org/archives/gimp-developer-list/2015-February/msg00051.html

Looking at what Mitch said, it seems exporting GIO_EXTRA_MODULES is only be needed if glib is also built in the prefix. So sorry for the noise! if you didn't also build glib in the prefix.

For the next person trying to build GIMP from git who might stumble over this thread, a few other "why it doesn't work and what to do" are documented here:

But you must install babl and gegl from git in order to build gimp from git.

Just install them from git too, into the same prefix, using the same environment.

It's likely that you're missing LD_LIBRARY_PATH when you're loading GIMP. While you're starting GIMP that was compiled from Git it is loading GEGL libraries from other sources. You should do the following (assuming GIMP, GEGL, and BABL were installed under /usr/local prefix by default):

LD_LIBRARY_PATH=/usr/local/lib gimp-2.9

GIMP will then look to /usr/local/lib for its GEGL and BABL libraries instead of /usr/lib (which is where it is typically installed by a package manager).

With everyone telling how they build GIMP I would like to add how to avoid setting the LD_LIBRARY_PATH: baking the path into the executable.

I am installing everything (babl, gegl and GIMP) to /opt/gimp-GIT/ (which belongs to my user so I don't need root to install). These are my calls to configure the three, afterwards a simple "make -j5 install" is enough.

babl: LDFLAGS="-Wl,-rpath -Wl,/opt/gimp-GIT/lib" CFLAGS="-march=native -O3" CXXFLAGS="$CFLAGS" ./autogen.sh --prefix=/opt/gimp-GIT/

gegl (disabling stuff just because I don't need it): PKG_CONFIG_PATH="/opt/gimp-GIT/lib/pkgconfig" LDFLAGS="-Wl,-rpath - Wl,/opt/gimp-GIT/lib" CFLAGS="-march=native -O3" CXXFLAGS="$CFLAGS" ./autogen.sh --prefix=/opt/gimp-GIT/ --disable-docs --without-libavformat -- without-vala

GIMP (with mypaint being installed in /opt/mypaint/): PKG_CONFIG_PATH="/opt/gimp-GIT/lib/pkgconfig:/opt/mypaint/lib/pkgconfig" LDFLAGS="-Wl,-rpath -Wl,/opt/gimp-GIT/lib" CFLAGS="-march=native -O3" CXXFLAGS="$CFLAGS" ./autogen.sh --prefix=/opt/gimp-GIT --enable-python

Each of them is one line.
