Created attachment 431158 [details] The ebuild. Yet more problems with "app-emulation/spice-0.13.0 fails to build - make[4]: *** No rule to make target '/spice.proto', needed by 'generated_client_demarshallers.c'. Stop" on GCC 5.3 (etc, etc) on a modern unstable. On Spice, going to -9999 fixes this. There is no -9999 for spice-gtk. Going to the upstream spice-gtk-0.31 fixes it. No big changes to the ebuild, just a change to how configure handles audio system (--enable-pulse or --enable-gstaudio rather than --with-audio=system)
The build issue is resolved in another commit, thanks for the report. commit 2f9879835a0e68dc9fc1f74133d653fb9e3ee2ff Author: Matthias Maier <tamiko@gentoo.org> Date: Sun May 1 14:50:48 2016 -0500 net-misc/spice-gtk: version bump to 0.31 Package-Manager: portage-2.2.26
