Description Bernhard Rosenkränzer 2021-08-07 19:45:22 UTC 
SUMMARY
The lut docker uses obsolete OpenColorIO 1.x APIs and doesn't currently build against OpenColorIO 2.0.
Most porting is fairly straight forward (simply adding a getDefaultCPUProcessor()), only the DisplayTransform bits are a bit of a headache (at least to me, being mostly unfamiliar with OCIO).


STEPS TO REPRODUCE
1. Update OpenColorIO to 2.0.x
2. Try to build Krita

OBSERVED RESULT
Fails to build

EXPECTED RESULT
builds and works

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: OpenMandriva Cooker

Comment 1 Halla Rempt 2021-08-07 19:47:34 UTC 
If it's straightforward, please provide a patch?
Comment 2 laguest@archeia.com 2021-08-16 16:19:27 UTC 
It's not really straight forward, here's what I get:
