gtkglextmm fails to build

[n.a.hawes@…]

The gtkglextmm port fails to build with the error below. It looks like the causes is that gtk2 and gtkmm are out of sync version-wise: ​https://bugs.launchpad.net/ubuntu/+source/gtkmm2.4/+bug/660787

Patch to make gtkglextmm compile with newer versions of GTK/gtkmm

[staffan@…]

Although the symptoms are the same, this is in fact not a problem caused by mismatching versions of GTK and gtkmm. It's an issue with gtkglextmm not being compatible with later versions of GTK/gtkmm. Quoting from the comment in the applied patch:

# Fix build issue where build fails due to GDK_DISABLE_DEPRECATED being enabled.
# The order in which files are included matters here. gtkmm does some funky
# stuff to undefine GDK_DISABLE_DEPRECATED, if defined, before including gdk.h
# as it needs some deprecated functionality. Including gtkglwidget.h before
# widget.h causes gdk.h to be included without GDK_DISABLE_DEPRECATED being
# undefined, and gtkmm never gets the chance to work its undefine magic.

Fortunately, the fix is simple!

To the maintainer (or someone with commit rights): please apply the attached Portfile patch (Portfile.diff), add a files directory and put the attached file patch-gtkglext_gtkmm_gl-widget.cc.diff into the files directory.

I'll see if I can file a bug upstream as well, if it hasn't already been reported.
