libmypaint is now needed to build gimp-9999 https://github.com/mypaint/libmypaint "libmypaint, a.k.a. "brushlib", is a library for making brushstrokes which is used by MyPaint and other projects. http://mypaint.org This is a self-contained C library that is isolated from MyPaint. It allows other applications to make use of the MyPaint brush engine." Attached is my first ebuild, so check it carefully. It works compiles fine here. See bug 569346.

Upstream ticket https://github.com/mypaint/mypaint/issues/535 seems related. Markos, as the maintainer of media-gfx/mypaint, do you have any preferences / wishes / requirements on future media-libs/libmypaint packages?
I gave the attached live ebuild a closer look and a spin now: * The enable_gegl="true" part should go to src_compile only or as well * Installing conflicts with two files /usr/share/locale/zh_TW/LC_MESSAGES/libmypaint.mo /usr/share/locale/zh_CN/LC_MESSAGES/libmypaint.mo owned by media-gfx/mypaint. * I also run into weird compile errors if I don't post-process Gentoo-wide CFLAGS like CFLAGS="$(sed 's,--param [^ ]\+,,g' <<<"${CFLAGS}")" The flag-o-matic eclass way seems to be running strip-unsupported-flags. I have reported that issue upstream: https://github.com/mypaint/libmypaint/issues/30
Sebastian please see bug 569738. Did you manage to emerge GIMP?
(In reply to DrSlony from comment #4) > Sebastian please see bug 569738. Did you manage to emerge GIMP? With libmypaint installed: yes.
Please see bug 569738 again.

Is it really that gimp block mypaint?
(In reply to Serge Gavrilov from comment #11) > Is it really that gimp block mypaint? I'm afraid before we have a version of mypaint in Gentoo that (a) uses libmypaint or (b) provides libmypaint-gegl the answer for Gimp 9999 is yes. Any other ideas for a fix?
It seems that GIMP mypaint tool is unusable without MyPaint installed (no brushes). The only blockers are libmypaint.mo files from libmypaint. I install the packages in the following order: 1) libmypaint (ebuild without conflict with mypaint) 2) GIMP 2.9 Now GIMP cannot find any mypaint brushes 3) rm -f `locate libmypaint.mo` 4) mypaint Now everything seems to work in a proper way (both mypaint & GIMP)
Hello Using libmypaint-9999.ebuild r3 attached above, emerging media-libs/libmypaint-9999 today fails with: >>> Compiling source in /var/tmp/portage/media-libs/libmypaint-9999/work/libmypaint-9999 ... scons -j8 enable_openmp=1 enable_gegl=true enable_shared=true prefix=/usr scons: *** No SConstruct file found. I asked on #gimp and was told that libmypaint is being autotooled and we should try the autoconf.sh / configure type of incantations instead. I am used to compiling manually, but I don't know how that is done in an ebuild. Could someone help update the ebuild so that we can get this to compile, as gimp-9999 depends on it? P.S. I tried this https://bpaste.net/show/b67eda274b49 and it emerged well. No idea whether its safe though.
My ebuild mod probably didn't work, because compiling gimp-9999 fails with: GIMP configuration failed. The following mandatory dependencies are missing: - libmypaint >= 1.3.0

Created attachment 435140 [details] libmypaint-9999.ebuild r4 The attached libmypaint-9999.ebuild r4 leads to a successfully compiled libmypaint which gimp-9999 picks up and compiles successfully against. I make no claims as to it being safe - use at your own risk.
1.3.0_beta1 now in Gentoo: https://github.com/gentoo/gentoo/commit/76d49b5609a56bdc5b817ac65be4593b2cb450a7
