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.

nedludd commented on 2021-07-16 22:54 (UTC)

I uninstalled jasper and opencv2 built properly. Thanks for the tip!

@nedludd: I've jasper:2.0 installed, it's incompatible with opencv2 but gets dragged into by cmake and introduce the issue. ~I can't see immediate solution, you can build opencv2 in clean chroot with extra-x86_64-build provided with devtools package, or uninstall jasper for a moment to build opencv2.~

[Edit] Fixed: malformed cmake flags 5feaf8edb556, force build jasper locally 00d6b2f8ccb2
