Ubuntu UI Toolkit no longer builds on precise, quantal and raring

Forgot some links.

I believe if this is to be supported, libthumbnailer-dev needs packaged on the other distros. A separate bug may be needed for this.

Status changed to 'Confirmed' because the bug affects multiple users.

This is more than just an inconvenience. The toolkit has diverged enough since this problem hit that code that runs on precise, quantal, and raring will no longer run on saucy or trusty, and vice versa. In particular, the internal API used by OptionSelectorDelegates has changed; see #1257529.

Currently the dash uses the thumbnailer (image://thumbnail/foo image paths come from the scopes), and some central place to cache and create thumbnails is needed, see https://bugs.launchpad.net/unity8/+bug/1224998

There is a possible fix for thumbnailer at lp:~jpakkane/thumbnailer/raringfix. Could someone verify if that fixes it on older versions?

Fix committed into lp:thumbnailer at revision 61, scheduled for release in thumbnailer, milestone Unknown

As of today, the full fix is in thumbnailer trunk. With a new PPA UITK is now buildable on precise again.

Is this going to make it into the ubuntu-sdk-team ppa? If so, on what sort of time scale?

Also, I notice that the ubuntu-ui-toolkit is no longer building for saucy, due to missing 'qtbase5-dev (>= 5.2~)'. Since precise, quantal, and raring are still on 5.0.2 in this ppa, I fear they will still fail to build even when the thumbnailer is fixed.

Thumbnailer is still not building for raring https://launchpadlibrarian.net/152875688/buildlog_ubuntu-raring-i386.thumbnailer_1.0%2B13.10.20131008bzr56raring0_FAILEDTOBUILD.txt.gz

no thumbnailer package for raring, quantal, precise. I'm re-opening the bug.

Condensed version of the email I sent you:

the package builder uses revision 56, trunk (which has the fix) is at 62. Package build configuration needs to be changed to use trunk.

This fails to build even with r62: http://paste.ubuntu.com/6874966/

The obvious changes (http://paste.ubuntu.com/6874968/) didn't help.

You need a PPA with GStreamer 1.0. It should be in the sdk PPA as discussed above.

We have gstreamer 1.0 backported to the PPA, but the thumbnailer build fails to build: https://launchpad.net/~ubuntu-sdk-team/+archive/ppa/+build/5085931

Do we really need this image provider in UITK? Why is it not a separate module+package?

Which apps are using it now, and why can't they depend on the thumbnailer instead of having it in UITK?

Video thumbnails are generated for the dash using the thumbnailer, long-term plan was indeed to take it out of UITK, with an all-purpsose image cacher (see bug #1224998).

This is exactly the same issue as in comment #12. The builder uses revision 56, it needs to use trunk (r61) which has the fix.

This bug was fixed in the package thumbnailer - 1.0+14.04.20140218-0ubuntu1
