The G_CONST_RETURN define in GLib is, and has always been, a bit fuzzy. We always used it to conform to the platform, at least for public-facing API. At first I assumed it has something to do with brain-damaged compilers or with weird platforms where const was not really supported; sadly, it's something much, much worse: it's a define that can be toggled at compile-time to remove const from the signature of public API. This is a truly terrifying feature that I assume was added in the past century, and whose inception clearly had something to do with massive doses of absynthe and opium — because any other explanation would make the existence of such a feature even worse than assuming drugs had anything to do with it. Anyway, and pleasing the gods, this dubious feature is being removed/deprecated in GLib; see bug: https://bugzilla.gnome.org/show_bug.cgi?id=644611 Before deprecation, though, we should just remove its usage from the whole API. We should especially remove its usage from Cally's internals, since there it never made sense in the first place. |

Clutter
What is Clutter?
Clutter is an open source software library for creating fast, compelling, portable, and dynamic graphical user interfaces.
Requirements
Clutter currently requires:
On X11, Clutter depends on the following extensions:
- XComposite
- XDamage
- XExt
- XFixes
- XInput (1.x or 2.x)
- XKB
If you are building the API reference you will also need:
If you are building the additional documentation you will also need:
- xsltproc
- jw (optional, for generating PDFs)
If you are building the Introspection data you will also need:
If you want support for profiling Clutter you will also need:

Clutter is licensed under the terms of the GNU Lesser General Public
License, version 2.1 or (at your option) later: see the COPYING file
for more information.
Building and Installation
To build Clutter from a release tarball, the usual autotool triad should be followed:
- ./configure
- make
- make install
To build Clutter from a Git clone, run the autogen.sh script instead
of the configure one. The autogen.sh script will run the configure script
for you, unless the NOCONFIGURE environment variable is set to a non-empty
value.
See also the BuildingClutter page on the wiki.
Versioning
Clutter uses the common "Linux kernel" versioning system, where even-numbered minor versions are stable and odd-numbered minor versions are development snapshots.
Different major versions break both API and ABI but are parallel installable. The same major version with differing minor version is expected to be ABI compatible with other minor versions; differing micro versions are meant just for bug fixing. On odd minor versions the newly added API might still change.
The micro version indicates the origin of the release: even micro numbers are only used for released archives; odd micro numbers are only used on the Git repository.
Contributing
If you want to hack on and improve Clutter check the HACKING file for
general implementation guidelines, and the HACKING.backends for
backend-specific implementation issues.
The CODING_STYLE file contains the rules for writing code conformant to
the style guidelines used throughout Clutter. Remember: the coding style
is mandatory; patches not conforming to it will be rejected by default.
The usual workflow for contributions should be:
- Fork the repository
- Create a branch (
git checkout -b my_work) - Commit your changes (
git commit -am "Added my awesome feature") - Push to the branch (
git push origin my_work) - Create an Bug with a link to your branch
- Sit back, relax and wait for feedback and eventual merge
Bugs
Bugs should be reported to the Clutter Bugzilla at:
http://bugzilla.gnome.org/enter_bug.cgi?product=clutter
You will need a Bugzilla account.
In the report you should include:
- what system you're running Clutter on;
- which version of Clutter you are using;
- which version of GLib and OpenGL (or OpenGL ES) you are using;
- which video card and which drivers you are using, including output of glxinfo and xdpyinfo (if applicable);
- how to reproduce the bug.
If you cannot reproduce the bug with one of the tests that come with Clutter source code, you should include a small test case displaying the bad behaviour.
If the bug exposes a crash, the exact text printed out and a stack trace obtained using gdb are greatly appreciated.
