gtk+-2.18.6 has dependencies in it that arent dependencies. The x11-libs/libXrandr and x11-libs/libXcomposite are not required. I modified the ebuild to remove them, the package compiled, and gtk+ apps work just fine without them. Granted, an app which wants either of those 2 wont have them, but then they should controlled via USE flags. Reproducible: Always Steps to Reproduce: 1. mkdir -p /usr/local/portage/x11-libs 2. cp -a /usr/portage/x11-libs/gtk+ /usr/local/portage/x11-libs 3. vi /usr/local/portage/x11-libs/gtk+/gtk+-2.18.6.ebuild (and remove deps) 4. ebuild /usr/local/portage/x11-libs/gtk+/gtk+-2.18.6.ebuild digest 5. emerge gtk+
The are clearly listed as depends in configure.in file that you can read in, for example: http://git.gnome.org/browse/gtk+/tree/configure.in
Where? I see checks for Xrandr and Xcomposite, but I see them as optional. If they were required, you'd see a AC_MSG_ERROR call, but there isnt one. So not dependencies.
Heres some additional proof. A box with the unmodified ebuild: # ldd /usr/lib/libgtk-x11-2.0.so | grep -Ei "(Xrandr|Xcomposite)" libXrandr.so.2 => /usr/lib/libXrandr.so.2 (0x00007f284a613000) libXcomposite.so.1 => /usr/lib/libXcomposite.so.1 (0x00007f2849dde000) # The box I built without Xrandr and Xcomposite: # ldd /usr/lib/libgtk-x11-2.0.so | grep -Ei "(Xrandr|Xcomposite)" # ^^no output
If they are automagic, we have to decide whether to patch the build system or just force them as mandatory. Cfr. http://www.gentoo.org/proj/en/qa/automagic.xml Feel free to ask upstream about those… fwiw Xinerama had a similar story (see my own bug #118744).
