Freeglut needs migration to multiarch

This was done deliberately, and is documented in the NEWS.Debian file for this package:

  * In addition, some libraries have been dropped from this package despite
    not yet being multiarch-ready because it's not clear why they were
    included. If you have 32-bit programs that require one of these
    libraries, please file a bug report with 'ubuntu-bug ia32-libs' explaining
    which library you need and what application you need it for, so that
    the library can be readded.

    - freeglut3

What is your use case for 32-bit libglut?

I need libglut.so for "FoldIt" program. The binaries for linux are only in 32 bits http://fold.it/portal/

Ok. This is certainly an argument for adding it back to ia32-libs (probably via a dependency on the i386 package in precise).

As a workaround, you can probably just run 'sudo apt-get install freeglut3:i386' on your system with no adverse side effects, since you are unlikely to have a need for the 64-bit freeglut library at the same time.

And freeglut should be made multiarch-coinstallable for precise as well.

thanks for your answer.
I'm unlucky : I need freeglut both 64bits and now 32 bits. So I'd manually unpacked freeglut3:i386 and copied libs on /usr/lib32.

Bug #885652 and Bug #859038 seem awfully similar.

I added a precise task for this to do a SRU for a multiarch freeglut similar to the SRU done for libbonobo (#977947).

Created a test PPA here: https://launchpad.net/~mvo/+archive/freeglut-multiarch

The amd64 version tells me that the build will start in 4 days, I hope its lying.

This is the reason the Fieldrunners game (part of the new HIB a3 promotion) is not installable in 64-bit Ubuntu.

If you are affected by this because of Fieldrunners, feel free to subscribe to this bug for updates but please don't comment. We can't make the fix happen any faster.

I uploaded the updated library into precise-proposed now and its waiting in the SRU queue for review.

I also uploaded the rdependencies to the PPA for test, please do not use this PPA for real stuff, its just there to test the rebuilds.

Fwiw, all amd64 rdepends in the PPA are build now without a issue.

This change is not needed for multiarch because the package does not use dh(1) for building - it passes --libdir in debian/rules instead. It's best to not include this change in an SRU - and easier than verifying that there are no other behavior changes.

This doesn't look like a very correct way to implement a debugging package. Debugging packages should normally contain only the detached symbols, where this seems to be including a complete .so?

Thanks for the review Steve!

AFAICT one of the changes is necessary to make the mutlarch transition work. We have the following options

(1) remove the debian/rules "cp" AND switch compat level 9:
  this will result in ./usr/lib/debug/.build-id/f4/7892f47cb94a3d0023eead658b8da482b90f84.debug in the freeglut3-dbg package which is what debian/sid and quantal are having (size 269979)

(2) keep the debian/rules cp AND revert to compat level 7:
  - this will result in ./usr/lib/debug/usr/lib/x86_64-linux-gnu/libglut.so.3.9.0 in freeglut3-dbg, so a proper multiarch path

(3) revert both changes: this will result in a non-multiarch path /usr/lib/debug/usr/lib/libglut.so.3.9.0 in the freeglut3-dbg package for all architecture so its not a option

I like option (2) best but I'm happy with option (1) as well. Whatever is less risky and more likely to get accepted in the SRU.

I wouldn't say it's not an option to not revert both changes. In that case the freeglut3-dbg package would just not be marked Multi-Arch: same.

But in any case, reverting both those changes gets me a -dbg package with these contents:

-rw-r--r-- root/root 508467 2012-08-23 00:54 ./usr/lib/debug/usr/lib/x86_64-linux-gnu/libglut.so.3.9.0

That looks like a correctly arch-qualified path already to me.

Thanks again Steve, you are right, reverting both changes results in the -dbg package that contains the right multiarch path. I re-uploaded a new version with these changes to precise-proposed now.

Hello Guilllermo, or anyone else affected,

Accepted freeglut into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/freeglut/2.6.0-1ubuntu3 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 change the bug tag from verification-needed to verification-done. If it does not, 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!

Steve, you simply rock! Thanks a lot for your review and help with this.

Confirmed this is now working with Fieldrunners on 64bit precise with the fix in place.

The verification of this Stable Release Update 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 regresssions.

This bug was fixed in the package freeglut - 2.6.0-1ubuntu3
