https://git.gnome.org/browse/gimp/commit/configure.ac?id=44d5e7adcd6c8d3073a3cc9d71dee495ee58cf25 As of this commit, gimp-9999 will fail to compile because it can't find a binary named "gegl", because in Gentoo the binary gets a version suffix making it "gegl-0.3".
This seems to work: GEGL="/usr/bin/gegl-0.3" emerge -v gimp though compilation fails later on because libmypaint-gegl is currently missing.
Using my ebuild from bug 569548, compilation of gimp-9999 starts, but dangerously fails when gegl makes icons: /usr/bin/gegl-0.3 -x \ "<gegl> \ <node operation='gegl:invert-linear'></node> \ <node operation='gegl:load'> \ <params> \ <param name='path'>../../icons/Symbolic/12/gimp-swap-colors.png</param> \ </params> \ </node> \ </gegl>" -o 12/gimp-swap-colors.png * ACCESS DENIED: open_wr: /dev/nvidiactl * ISE:write_logfile: unable to append logfile: /var/log/sandbox/sandbox-25291.log * ../../sandbox-2.6/libsandbox/libsandbox.c:check_syscall():879: failure (Bad file descriptor): (...) /proc/25474/cmdline: /usr/bin/gegl-0.3 -x <gegl> <node operation='gegl:invert-linear'></node> <node operation='gegl:load'> <params> <param name='path'>../../icons/Symbolic/12/gimp-menu-left.png</param> </params> </node> </gegl> -o 12/gimp-menu-left.png Perhaps its the "../../" after "<param name='path'>"? Complete build log: https://bpaste.net/raw/8b7bfd4cb6db I need assistance here, don't know how to proceed.
For the record, I have a command "gegl" around, but it's from 0.2 which can be installed in parallel to 0.3.4: # which gegl /usr/bin/gegl # qlist media-libs/gegl:0 | fgrep /bin /usr/bin/gegl

Fixed. You will still need media-libs/libmypaint installed (bug #569268) to successfully compile Gimp 9999 as that became a hard dependency but is not in Gentoo, yet. # git show --stat | sed 's,@gentoo.org,@g.o,' commit 2eb639c54ae806e6eb53acf44593a24851f1d3d1 Author: Sebastian Pipping <sping@g.o> Date: Thu Dec 24 01:19:24 2015 +0100 media-gfx/gimp: Merge 2.9.2 into and fix 9999 (bug #569346) Package-Manager: portage-2.2.26 media-gfx/gimp/gimp-9999.ebuild | 49 ++++++++++++++++++++++++----------------- 1 file changed, 29 insertions(+), 20 deletions(-)
