gtk 2.6/2.8 vs 2.10

Hi,

A while ago gtk 2.10 was added to OE with a negative default preference since not all the
patches have been forward ported yet. Gtk 2.10 also bumped their ABI version to 2.10,
which leads to some interesting problems:

* do_install for packages dependant on gtk+ breaks since ${libdir}/gtk-2.0/2.4.0/ is now
${libdir}/gtk-2.0/2.10.0/
* some package build against 2.8 but not against 2.10 and vice versa

A lot of these problems can be solved with 'preferred-gtk-2.8-versions.inc', but ideally
we'd want a way to get the gtk PV from inside other recipes (e.g. gtk-engines).

Does anyone have a good idea on how to handle all this?

regards,

Koen

I just checked my gtk+-2.10.0 and gtk+-2.0.pc contans the following
line.

gtk_binary_version=2.10.0

If this exists for all gtk+ we could parse ths file in install and set
${LIBV} with it.

It exists for 2.8.9 so this approach looks promising. Also note the
string is not PV as its 2.4.0 for 2.8.9 so whilst PV would provide some
help, it doesn't really solve this problem.

Cheers,

I think Graeme's solution should solve this.

These need versioned DEPENDS eg. DEPENDS = "gtk+ (>= 2.10.0)". Could
someone try and see if it breaks anything with the current bitbake? I'd
like to see the metadata starting to contain this data, even if bitbake
itself doesn't use it yet so when we do implement it, it should all just
work...

Cheers,

Richard
