Bug 598674 – media-libs/opencv-3.1.0 does not build against dev-util/nvidia-cuda-toolkit-8.0.44

• Status: RESOLVED FIXED
• Product: Gentoo Linux

Created attachment 452076 [details, diff]
Disable GraphCut for CUDA 8+

The reason is, that "GraphCut" was deprecated with CUDA-7.5 and eventually removed in CUDA-8.0.

With the attached patch media-libs/opencv-3.1.0-r5 built and merged just fine.

I already found the patch in upstream and confirmed it. This fix will be included in -r6 with other fixes. :)

I have a testing ebuild here if you want to try it.
https://github.com/dracwyrm/gentoo-ebuilds/tree/master/media-libs/opencv

Hopefully contains fixes for other bugs.

Apart from me having to download XX and YY by hand, because "ebuild manifest" refuses to download from github and insists on mirror downloads, the ebuild worked like a charm!

--------
 # ebuild opencv-3.1.0-r6.ebuild merge
(...)
>>> media-libs/opencv-3.1.0-r6 merged.
--------

Meaning "opencv-3.1.0.tar.gz" and "opencv-3.1.0_contrib-75b3ea9.tar.gz". ;-)

I still need to test tesseract support to see if that's fixed among other things. Should be some depend fixes with contrib and even new glog and gflags support!

Odd that it didn't download from GitHub when it didn't find the files on the Gentoo Mirrors. I'll look into that.

Thanks for testing. :)

Fixed in OpenCV 3.1.0-r6. Thanks for reporting. :)
