[SRU] AUTORCC-generated resources always out-of-date with Ninja

Bug Description


 * people using Ninja to speed up the build, with AUTORCC-generated resources

[Test Case]

 * stuff is not regenerated due to a bug in cmake

[Regression Potential]

 * None

[Other Info]

The upstream bug report is here:


and was later moved to here:


It was fixed by Brad King in


and the fix is in CMake 3.5.2.

I would like to ask what is best: Should I should prepare a debdiff adding this patch to the 3.5.1 package in Xenial and request an SRU? Or is it reasonable to update the Xenial package to 3.5.2 (which is in Yakkety) outright?

Looking at the short list of changes in 3.5.2 [1], perhaps an SRU updating the Xenial package to 3.5.2 might not be completely out of the question?

@elvstone: a patch is always easier to apply, if it's applicable. SRU is rather complicated, especially if there are many cross-dependiciens on a package.

Probably xnox (just subscribed has an answer for this much, much better than me.)

patch fixing the issue

build ongoing at ppa:costamagnagianfranco/costamagnagianfranco-ppa

the debdiff above works with libarchive from updates.
With libarchive from backports an additional patch (Coming from Debian and later releases) is needed.

this debdiff (uploaded on ppa:costamagnagianfranco/boinc) should work

Hello Elvis, or anyone else affected,

Accepted cmake into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/cmake/3.5.1-1ubuntu3 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Changed in cmake (Ubuntu Xenial):
status: In Progress → Fix Committed
tags: added: verification-needed

-- Found LibArchive: /usr/lib/x86_64-linux-gnu/libarchive.so (found version "3.2.1")

so far so good.

tags: added: verification-done
removed: verification-needed

@elvis please confirm it too, this works:
cat CMakeLists.txt

cmake .

Excellent, thanks a lot. Will verify as soon as I'm back at work tomorrow (missed this email before I left today).

I can confirm this fixes the reported issue.

I can also confirm that LibArchive is found properly with xenial-backports enabled:

estan@newton:~/tmp$ cat CMakeLists.txt
estan@newton:~/tmp$ cmake .
-- Found LibArchive: /usr/lib/x86_64-linux-gnu/libarchive.so (found version "3.1.2")

Thanks a lot for fixing this so fast! No-op builds are now next to instantaneous, even with AUTORCC-generated sources, as they should be :)

The verification of the Stable Release Update for cmake has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
