Missing FreeType support in 14.04 LTS package

[Chris McFarland]

[Impact]

The current version of openscenegraph in Ubuntu Trusty cannot load FreeType fonts. This is because the build used its own CMakeModule to try to find the Freetype libraries, and when it couldn't find the libraries, this module of the program was excluded from the build. Therefore, any programs that attempt to use FreeType fonts for their text will result in the text using something like Courier New (or some other code-style, serif font).

[Test Case]

Use any program that uses openscenegraph and attempts to load a FreeType font. Flightgear is one example; in the case of this program, an error message is displayed saying that the Liberation fonts couldn't be loaded, and the text appears to be Courier New-like.

[Regression Potential]

Minimum. The actual changes are a change in how the FreeType libraries are found and some #include changes. The worst case is a build failure. Programs are expected to continue working and shouldn't need a recompilation.

[Original Description]

The current package (3.2.0~rc1-4) available for Ubuntu 14.04 is missing support for FreeType due to a build bug that is listed as fixed in 3.2.0~rc1-5. This results in very poor quality text in OpenSceneGraph applications that are running on 14.04 (which used to be fine in 12.04). There is a discussion of the bug on the Debian bug tracker (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=743169) for more information.

Is it possible to get this fix into 14.04?

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

[Chris J Arges (arges)]

Hello Chris, or anyone else affected,

Accepted openscenegraph into trusty-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/openscenegraph/3.2.0~rc1-4ubuntu0.1 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!

I tried installing openscenegraph/trusty-proposed (3.2.0~rc1-4ubuntu0.1) following Chris Arges's instructions, but unfortunately it did not fix the issue -- the font rendering appears the same as before, even with a full rebuild of affected software.

It looks like libosgdb_freetype.so is not getting installed with the proposed package.

[Saikrishna Arcot (saiarcot895)]

I haven't had a chance to verify this fix, but /usr/lib/osgPlugins-3.2.0/osgdb_freetype.so is certainly being installed.

[Chris McFarland (cmcfarla)]

Hmm... it looks like openscenegraph/trusty-proposed just has symlinks to a few .so files instead of the actual library files. The osgdb_freetype.so file actually gets installed with libopenscenegraph99/trusty-proposed, which wasn't getting installed on my system when I did apt-get install openscenegraph/trusty-proposed for some reason. Maybe I made a mistake configuring the package manager? In any case, I have the file now, but it's too late for me to do the testing today.

I'll set the tag back to verification-needed for now and update again the next time I can test it on the system (hopefully tomorrow). Sorry for the confusion.

[Chris McFarland (cmcfarla)]

I tested today with libopenscenegraph99/trusty-proposed installed and it fixed the font rendering issue.

[Saikrishna Arcot (saiarcot895)]

+1 from me as well; the font rendering issue isn't present here.

The verification of the Stable Release Update for openscenegraph 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.
