Sorry lads, I'm at the Polish Ukraine border helping allocate refugees. Expect no update until this hell is over, wish us luck. Have no time nor access to my rig and AUR keys to test/post updates. If you have a patch, ping me on email - I'll add you as co-maintainer. Posted with my old script - https://github.com/bartoszek/aur-post

I can confirm what Thenujan is getting with the

I see this from 2019. It doesn't help me but maybe someone: bug from 2019 inline link.

I've tried adding those flags and following some of those hints linked in the # github issues there and the # stackovereflow link there too but couldn't didn't help.

Build fails with

The opencv git repository is huge. Would you consider doing the cloning manually, with "git clone --depth 1 ...'? It seems like makepkg doesn't want to implement passing git flags for some reason (see https://bugs.archlinux.org/task/34677).

As per what has been mentioned in the opencv2 package, I needed to add these flags to _cmakeopts in order to get this compiled.

        '-D BUILD_JASPER=ON'
        '-D CMAKE_CXX_FLAGS="-std=gnu++11"')

@tom - the BUILD_JASPER line should fix your error.

In build section, it is better to set export LDFLAGS="-Wl,-rpath,/opt/${_pkgbase}/lib".

@nedludd: I've fixed PKGBUILD, should work with jasper installed now.
