opencv-4.9.0 doesn't build when I enable the cuda use flag with nvidia-cuda-toolkit-12.4.1 I did an emerge -ev opencv, thinking maybe I could get past it seeing as most people don't seem to be having this problem... but it still fails. I see some errors that seem to look like this commit from Arch: https://gitlab.archlinux.org/archlinux/packaging/packages/opencv/-/commit/30f9165f2387ef9dd0b02e3e54de2bc98acb1341 especially this patch: https://gitlab.archlinux.org/archlinux/packaging/packages/opencv/-/blob/main/fix-nppi-bufsize-type.patch?ref_type=heads Reproducible: Always Steps to Reproduce: 1.enable cuda use flag 2.update to nvidia-cuda-toolkit-12.4.1 (maybe 12.4.0) 3.rebuild opencv 4.fail Actual Results: Here's a part of the failure: In file included from

I accidentally removed the blocker. I have a PR to re-add that. It's unlikely to get fixed in 4.9 looking at upstream. I'll try to add 4.9.9999 and 5.9999 ebuilds so we can test that. Getting opencv to work with 12.4 would require to fix the cccl bug from https://github.com/NVIDIA/cccl/pull/1522. Not sure how likely that will be.
