Future of Qt4 recipes

Future of Qt4 recipes

[Burton, Ross]

[-- Attachment #1: Type: text/plain, Size: 845 bytes --]

Hi,

So, Qt 4.8.7 was released last month[1].  Support for Qt4 stops at the end
of 2015, and 4.8.7 is planned to be the last ever release of Qt4. It's
still mandated by the long-awaited LSB 5 but I think it's fair to say that
the majority of developers have moved to Qt5. So, what should we do with
Qt4 moving forward?[2]  I see several options:

1) There's still lots of people using Qt4 in production, please keep it in
oe-core!  (and revisit in six months time)
2) Move Qt4 recipes and classes to a meta-qt4 layer now so that oe-core 1.9
ships without Qt4, and anyone wanting full LSB compliance or Qt4 will need
to add that layer to their distro.

Personally, I vote for (2).  Any other comments?

I agree it is really widely used in production. I would leave it in as long as
the situation stays like this and Qt4 is maintained.

You know in my opinion we would be better with a little bit less fragmentation...

I tend to agree with Florian here, qt4 is widely used, and we shouldn't
drop it until it goes unsupported.

That said, it will be unsupported before the next release goes unsupported.

Tough call.

Exactly: a few months after 1.9 ships, Qt4 is officially dead.   So the
question remains, is Qt4 actually heavily used, or has everyone moved to
Qt5 already? (note that both Qt3 and Qt5 are maintained in their own
layers).

GNU Radio is still qt4. I am beating, but they are short GUI guys.

#2 sounds fine.

would recipes-lsb move out to its own layer too?

I agree with #2.

Argument that it's still used by many projects shouldn't be used against
layers :).
