Comment 1 Antonio Rojas 2025-04-06 07:52:02 UTC

This looks like a mismatch bewteen the openexr and imath versions used at build time (ie. you're building against system openexr, which I assume links to a system imath, yet you are using with a custom imath), rather than a problem in kimageformats. FWIW it builds fine here using openexr 3.3.

Comment 2 Kyle Devir 2025-04-12 05:21:00 UTC

@Antonio Rojas

I did a naive rebuild with the Arch imath PKGBUILD, along with openexr, and it seems that the issue is that imath was simply forgotten. Maybe it was never reported as broken, or something.

Shall report.

Comment 3 Antonio Rojas 2025-04-12 08:05:15 UTC

No, as I said, the problem is that you were mixing a local build of imath with a system openexr
