OpenJPEG failing tests on big endian #1204

nijel · 2015-04-22T09:05:50Z

Looks like there are quite some issues within the code when executed on big endian machine, see testsuite failures:

wiredfool · 2015-04-22T15:01:33Z

I've been testing on big-endian (ubuntu 12.04 PPC), and Jpeg2k has always had issues. I think there's something with the underlying library on that version. What version is is suse testing against?

nijel · 2015-04-22T17:28:48Z

It was openjpeg2-devel-2.1.0

wiredfool · 2015-05-13T17:58:41Z

Just got the PPC fired up here, and I'm seeing similar issues. (32bit, g4 mini on ubuntu 12.04). It's got openjpeg 2.1.0, and most of the jpeg2k bits are failing.

I'm seeing a slightly different error in TestFileIco which at least points to something:

Ico files are little endian, ref #1204

hugovk · 2015-05-29T15:30:39Z

(Partial) Fix #1232 is merged.

hugovk · 2019-02-17T09:42:20Z

Is this still an issue after the fix from #1232?

nijel · 2019-02-17T17:57:05Z

I don't see how ICO fix would relate to OpenJPEG bug...

Testsuites fail on big endian arch Upstream report: python-pillow/Pillow#3798 python-pillow/Pillow#1204

okurz · 2019-06-11T06:23:07Z

The links to the test results have changed:

https://build.opensuse.org/package/live_build_log/devel:languages:python/python-Pillow/openSUSE_Factory_PowerPC/ppc64 shows the always most recent build and test results on ppc64 (BE)
https://build.opensuse.org/package/live_build_log/devel:languages:python/python-Pillow/openSUSE_Factory_zSystems/s390x are the build and test results on s390x

Both show a lot of problems with the self-tests, eventually ending in an "Segmentation fault".

azaghal/pydenticon#10 is another related downstream issue.

radarhere · 2021-12-22T23:32:19Z

The opensuse builds are currently blocked by other packages.

I'm going to say that this is resolved by #5901, since then all tests mentioned here pass on our Big Endian CI job. Please let us know if there are still problems.
