If I build opencv enabling the openexr use flag, version 4.5.4 fails reporting a list of Ifm_3_1::* undefined references... starting with ' media-libs/opencv-4.5.4 fails to build due to undefined reference to Imf_3_1 class methods ' I have both openexr 2.x and 3.x installed, but it seems they cannot be found by my GOLD linker. In the attachments my build.log and the emerge --info output. Reproducible: Always Steps to Reproduce: 1. Enable openexr use flag 2. emerge media-libs/opencv 3. Actual Results: Build fails... Expected Results: Build successfully as previous versions...

Can you try not using gold first? It's rather dead for a start. This is possibly more likely to be trying to pull in both and then it barfs. We've seen a lot of that.
Looks like there's some upstream commits in the latest release which may help.

I've forced OpenEXR 2 here but that may have been the wrong call, was continuing the status quo. We can try 3 here, maybe.

Now I will try with 4.5.5 unstable release. Iade

Not clear that anything actually needs this and we don't have multilib support in imath right now (nor did it succeed when I tried to add it there).
