opencv4 @4.8.0_4+contrib build failure

[fmw42 (Fred Weinhaus)]

I was trying to install py39-opencv4 or py311-openc4 on Ventura on M1 Mac mini. Both installs gave error messages that they could not install opencv4.

Folks, does this issue still occur with the latest version of opencv4 (4.9.0)?

I just tested on x86_64 Big Sur and it built fine for me

Great to hear Eric!

@fmw42 Fred, how about you?

[fmw42 (Fred Weinhaus)]

No it still fails the same way when I try to install py311-opencv4 on my M1 Mac mini with Ventura complaining about the Chromaticities.

That might be related to ports imath and openexr, which were both updated a short time ago. (And those updates may not published for another hour-ish.)

Once an hour has passed, can you resync your ports tree, and update everything outdated?

Assuming that imath and openexr are updated, go ahead and retry installation of py311-opencv4.

[fmw42 (Fred Weinhaus)]

OK thanks. I will try later or tomorrow. As mentioned above, the error was related to OpenEXR Chromaticities.

[fmw42 (Fred Weinhaus)]

I tested again this morning to upgrade py311-opencv4 and it failed again with what looks like the same issue with OpenEXR Chromaticities. I have just uploaded the error log file. See attachments.

Any update on this ticket? Tried again today to install/upgrade and it failed again.
