Thanks for reminding me of Interval, as the code is a minor variant of Box, the same issues are there. Interval has the same labeled pixel semantics. We're using Box...

Yeah, in both places, they should be IMATH_EXPORT_CONST. If that fixes your issue could you let us know, and either submit a PR, or we can patch it. Thanks!

No worries. If you come back to it and encounter the issue again please feel free to continue the conversation here.

how did you build and/or install Imath? how are you building OpenEXR? I'm asking in terms of, what was your command line?

Thanks for the steps! Good catch on the zlib naming, that needs attention in our build script for sure.

My apologies, it looks like I didn't post my results. [Edit] this halfLimits problem has been repaired. Note that there's a new issue ~ I'm not sure why CI didn't...

Also, I didn't encounter an issue with zlib, so maybe that's been sorted out since then.

I can't reproduce the problem with linking the look up table here. [Edit: this problem has been resolved] Removing that line in halfLimits.h is necessary if you pull Imath today...

I patched halfLimits.h, so now you can ignore that problem.

Sorry it's taken me a long time to understand the issue. The problem is not building OpenEXR, the problem is linking OpenEXR to your own projects. I can keep investigating.
