[Gimp-developer] Problem with GIMP 2.9.x build dependencies

[Carmelo DrRaw <aferrero1975 gmail com>]

Dear GIMP experts,

I am having troubles to compile the dependencies required to build the latest GEGL/GIMP versions from GIT.

The problem I am facing is the following:

* on one hand, GEGL requires GLIB > 2.44.0

* on the other hand, PyGTK (needed to have python support in GIMP) wants pygobject-2.0, whose latest version 
I could find is 2.28.6
However, this version must be compiled against a gobject-introspection version prior to this commit: 
https://mail.gnome.org/archives/commits-list/2011-August/msg03069.html 
<https://mail.gnome.org/archives/commits-list/2011-August/msg03069.html> (Deprecate ErrorDomain), otherwise 
one gets compilation errors due to undefined enum values. So this brings me to 1.29.16 as the latest usable 
gobject-introspection version (at least according to release dates, see 
http://ftp.gnome.org/pub/GNOME/sources/gobject-introspection/1.29/ 
<http://ftp.gnome.org/pub/GNOME/sources/gobject-introspection/1.29/>).
However, gobject-introspection-1.29.16 cannot be compiled against glib-2.44.0 because of g_module_* functions 
having been moved into a sport library, which gobject-introspection-1.29.16 is not linking…

Am I doing something wrong? Is there a recommended set of library versions for compiling GIMP? Or should I 
patch object-introspection to add the missing glib library?

Thanks a lot in advance!
