Bug#755874: gobject-introspection: [patch] use multi-arch pathes for the .typelib files

[Michael Vogt]

Package: gobject-introspection
Version: 1.40.0-1ubuntu0.1
Severity: wishlist
Tags: patch

Hello,

to install a cross build environment it would be great if the typelibs
could be co-installed in a multiarch environment. Right now all
foo-dev packages depend on gir1.2-foo. So when trying to install foo-dev
for cross-building that won't work because the gir1.2-foo is not
multi-arch ready. The attached patch moves gobject-introspection to
multiarch triplet pathes, adds compatiblity for the old path and 
updates dh_girepository to look at both the new and old path. 
This part could probably do with a review of someone more familiar 
with perl than I am :)

With this change most packages that ship a gir1.2-* package need a small
change to their debian/gir1.2-foo.install file:
 - usr/lib/girepository-1.0/* 
 + usr/lib/*/girepository-1.0/*
Without they will fail to build.

Here is a draft announcement:
"""
Dear developers,

we would like to move the gnome introspection typelib data from
/usr/lib/girepository-1.0 to /usr/lib/<triplet>/girepository-1.0
so that we can install them in parallel on a multiarch system.

A updated version of gobject-introspection is ready in experimental that will
look into the new multiarch path and have the old path as a fallback.

But because the pkg-config libdir is now also a multiarch path most
gir1.2-* packages need adjustments to their debian/install file(s).

The change is straightforward, just change your debian/install file:
- usr/lib/girepository-1.0/* 
+ usr/lib/*/girepository-1.0/*

because the typelib files are now in e.g. /usr/lib/x86_64-linux-gnu.

Thanks,
"""

Thanks for your consideration!
 Michael
