Well an %if 0%{?fedora} > 34 fixed that, but there's a stranger issue I
still need to investigate as I've seen this in more than one package, but
specifically on prusa-slicer...

CMake detects Imath, has include and link commands during compilation (only
links with target sla_print_tests), but Imath isn't in the Requires of the
RPMs. It doesn't need OpenEXR anymore because OpenVDB doesn't need it, so
that part of the mystery is solved.

Here's a scratch build which hasn't finished but but I assume will show the
above:
https://kojipkgs.fedoraproject.org//work/tasks/5228/73385228/build.log

Similarly in openshadinglanguage (but slightly different) it detects both
OpenEXR 3 and Imath 3, it only links with Imath[1], but then Imath doesn't
end up in the Requires[2] of the RPMs.

Thanks,
Richard

That one should be fixed.


Could very well be that my notes are stale. Lots of moving parts to this
update :)


Well kinda... The patch fixes building for rawhide but it fails on f34. Doesn't 
look like the "fix" is backwards compatible...


The patch is only applied on F35+. It is not the best solution, but it is 
pragmatic.

This is just a note that luminance-hdr did move to openexr2, and will 
remain there for the foreseeable future—unless somebody writes a 
nontrivial patch for 3.x support, or the recently-absent upstream picks 
up development again. The curious may consult 
https://bugzilla.redhat.com/show_bug.cgi?id=1968167 for details.

I've only done like two builds, so I could probably just throw them away..

I could also just push all the commits and hope the mass rebuild takes care
of them? :)

So ... just so you know, tomorrow might not be the best time to do
this, since that will collide with the mass rebuild for F35:
https://pagure.io/releng/issue/10219

If you have that option, I would wait with building all your things in
a side tag until the mass rebuild is done and the f35-rebuild side tag
has been merged to rawhide. Otherwise you'll have to account for
possible in-flight builds of your stuff ...
