Build broken for xUbuntu 18.04 OBS third party master packages

Software darktable
1

Hello,

Since sometime ago I used to update Darktable from OBS packages. Today, I wanted to update from 2.7.0 to 3.0.0rc0 to see the new improvements.

Then I visited darktable.org → snapshots from the master branch → ubuntu → Grab binary packages directly
 and I saw that commit hash was different for xUbuntu 18.04.

This package is behind the rest of versions for 5 days.

Looking for some clues, I’ve found failed xUbuntu 18.04 builds in the build service. You can find here its log:

I don’t know who is in charge of these builds, it’s just to notify it.

Thanks,
Rafa

@darix is the maintainer. I’m sure he will fix it as soon as he is able.

well I have 2 options now … turn off LTO on all deb based distros or remove 18.04 from the list … I rather lean towards option 2

fwiw: If an app is slow without LTO, it may be a bit faster with LTO, but nothing to write home about. I would turn off LTO…

Before to take any decision.

Do we have statistical data about the usage/downloads of this package?

For me it isn’t a problem to upgrade to 19.10, but for other users it could be a problem or maybe there are no almost others users :man_shrugging:t2:

BTW thanks @darix for the maintenance of the packages :blush:

we dont have download stats on download.opensuse.org

ok turned off LTO for deb based stuff.

Thank you!

As I couldn’t find my 2017(?) LTO benchmark, I added a BENCHFUN to ImageProcessor::normal_pipeline() in RT and took the median of batchprocessing the same Canon 6D CR2 11 times (current dev, default profile, Debian 10 AMD64 VM with 48 cores on idle host, GCC 8.3).

  • -DWITH_LTO=OFF: 3805ms
  • -DWITH_LTO=ON: 3694ms

So that’s a speedup of 1.03.

Best,
Flössie
