gtk3 should not only be a make dependency, as libraries are linked against it (e.g. libhighgui). If gtk3 gets removed after building this, applications linking against this library will get undefined references.

Updated to v3.4.12. Thanks @Windfisch again!

Windfisch commented on 2020-11-15 11:49

In OpenCV 3.4.12, the jpeg2000_jasper patch hsa been merged into upstream and should not be necessary any more to apply in the PKGBUILD.

it seems to be working after i installed tesseract :)

I had error with building opencv_imgproc:

@maximmasterr @savnkk

I built this today with up-to-date system packages (around 2020-10-15 05:00 UTC). One machine is with intel cpu and has built this package before. The other machine is a new amd cpu machine with a clean newly installed arch system. On both machines, this package was successfully built.

Maybe some wired issues related to your building environments?

savnkk commented on 2020-10-05 08:04

I had issues compiling. I was getting the following error. /usr/bin/ld: ndefined reference to `tbb::interface7::internal::task_arena_base::internal_max_concurrency(tbb::interface7::task_arena const*)' when it compiles opencv_version.

I think tbb isn't properly declared in its target-link-libaries.

For now, I have turned off tbb in the PKGBUILD -DWITH_TBB=ON \ -DWITH_TBB=OFF \

I have error with installing opencv3-opt

/usr/bin/ld: ../../lib/ undefined reference to `cv::hal::opt_SSE4_1::div32f(float const*, unsigned long, float const*, unsigned long, float*, unsigned long, int, int, double const*)'

And many lines like that Here is log until make

@MichaelChou, thanks for the prompt fix!

@xzz53 @marcin

My bad. Fixed now. I deliberately keep pkgrel unchanged.

If you don't care about integrity check you can skip it:

git clone
cd opencv3-opt
makepkg -is --skipinteg
