Here's one our chum
Panagiotis Nik prepared earlier:
http://slackonly.com/pub/packages/14.../games/gzdoom/
but clearly there is something broken (and a symlink is almost never the right answer). You should have all three of these files:
/usr/include/gtk-1.2/gtk/gtk.h
/usr/include/gtk-2.0/gtk/gtk.h
/usr/include/gtk-3.0/gtk/gtk.h
and when you build gzdoom, cmake should say this before it starts compiling the source:
Code:
-- Found X11: /usr/lib64/libX11.so
-- Found OpenGL: /usr/lib64/libGL.so
-- checking for module 'gtk+-2.0'
-- found gtk+-2.0, version 2.24.20
-- Found Xcursor at /usr/lib64/libXcursor.so
-- Looking for include file pthread.h
-- Looking for include file pthread.h - found
The obvious thing for you to try is to reinstall gtk+2 (it hasn't been upgraded in -current yet, so we can't blame that, but are you one of the recent dropline upgraders or something?)
