Thanks for the heads up abougouffa and all of you for the patience. I've updated the PKGBUILD to include qt5-base as well as the lapacke patch. Can confirm it builds fine in chroot. Let me know if there's any questions or any issues!

Hello @andrewSC, the package doesn't compile, there is a problem on the OpenCV codebase with newer versions of LAPACKE.

You need either to:

  1. disable it by removing the lapacke build dep and adding something like -DWITH_LAPACK=OFF to build options

  2. or much better, patch the file causing the problem (there is a patch in the ArchLinux codebase for this opencv/trunk/opencv-lapack-3.10.patch

I've tested this last option by modifying the PKGBUILD like this:

I'm having the very same error than @carlosnewmusic

I believe there is a typo in the PKGBUILD. Should it not be -DOPENCV_ENABLE_NONFREE=ON \

I also had to compile and install openblas-lapack instead of lapack + blas to successfully compile.

Why is SSE3 disabled for x86_64?

PKGBUILD:

[[ "$CARCH" = 'x86_64' ]] && _cmakeopts+=('-DCPU_BASELINE_DISABLE=SSE3 -DCPU_BASELINE_REQUIRE=SSE2')

Shouldn't it be the other way around?

[[ "$CARCH" = 'x86_64' ]] && _cmakeopts+=('-DCPU_BASELINE_DISABLE=SSE2 -DCPU_BASELINE_REQUIRE=SSE3')

At least on my architecture (broadwell) SSE3 is supported.
