Bug#665545: gtk2-engines: Including individual glib headers no longer supported

[biebl at debian.org]

Source: gtk2-engines
Version: 2.20.2-1
Severity: important
User: pkg-gnome-maintainers at lists.alioth.debian.org
Usertags: glib-single-include

Hi,


including invidiual glib headers has been deprecated for several years.

Starting with glib 2.32 it is now mandatory to include glib.h instead
of individual headers [1], or the compiler will generate an error.

With the notable exception of:
 glib/gi18n.h
 glib/gi18n-lib.h
 glib/gprintf.h
 glib/gstdio.h
Those header files are still meant to be included separately.


Development releases of 2.32 (2.31.x) are available in experimental.
During a test-rebuild gtk2-engines failed to build with the new glib [2].

Please update gtk2-engines at your earliest convenience, so once we move
the glib version from experimental to unstable, your package will remain
buildable.

Usually, simply replacing #include <glib/foo.h> with #include <glib.h>
is all that is needed (while keeping the above list of exceptions in
mind)
You can use the glib version from experimental to test if your package
builds correctly.


A simple shell script [3] has been written, that can help you
generate a patch which should fix the includes in most cases.
It's most likely not bug free and very limited, so please check the
resulting patch carefully.


Thanks!
