Subject: Clutter eglx packaging

Date: Tue, 6 Jul 2010 15:49:12 +0300

[Message part 1 (text/plain, inline)]

Package: clutter-1.0
Version: 1.2.8-1
Severity: wishlist
User: ubuntu-devel@lists.ubuntu.com
Usertags: origin-ubuntu maverick

The current Clutter source package only provides the glx OpenGL variant
of the Clutter library and it is therefore not suitable for use in
distributions targeting embedded devices.

The attached packaging changes (which are based on the 1.2.10 Ubuntu
package) add binary packages for the eglx-es11 and eglx-es20 flavours of
the Clutter library.

The most important "big-picture" changes from the current packaging in
Debian and Ubuntu are:

1. Production of multiple binary packages for variants of Clutter.
2. Use of dh7 instead of CDBS.
3. Use of 3.0 (quilt) format.

Are there any issues with the "big-picture" packaging changes (eg move
to dh7) that could block their adoption in Debian.

Thanks,
Alexandros

Again me ...

Adding Pochu who is the clutter maintainer on debian side.

Also CCing the debian bug (588244) and seb128 who taked over ubuntu desktop
role while didier is taking a sunbath ;).

Pochu, would be great if you could review the packaging from alf at best we
could merge this into debian and put it in experimental.

Thanks!

attached the debdiff vanilla ubuntu vs. unified packaging suggested.

on top of the changes described by alexandros we moved to debhelper 7 (as we
had to change it for a two run build anyway) and added symbol tracking.
