Please add openmpi at least as makedepends otherwise it fail to build in chroot

I think you can add provides=("opencv=$pkgver") to the 'opencv3-opt' subpackage.

Please no, it will not bring any benefit, packages that need opencv3 have already it listed in depends, adding provides=("opencv=$pkgver") will only make the Required by section of this page chaotic because there will be listed all pkgbuild that depends on opencv

Hi,

I think you can add provides=("opencv=$pkgver") to the 'opencv3-opt' subpackage.

(AUR helpers might not support versined provides lookup from AURweb as of yet, but they do so for already installed packages. Or if a third-party binary repo picks this up, then pacman will be able to fetch this via version constraint. Also, adding this would allow many more AUR users to easily discover the availability of this excellent package.)

the problem is not build, the problem is track the libs depends SOVERSION bumps. if not, when any libs provided by depends the SOVERSION is buped, the package silent fails load because the libs linked is not found (like posted in my comment)

adding the lib in provides. track pacman SOVERSION bups, and refuse/stops update until the package target is also bumped (update pkgrel). force the user force install the update and then force rebuild the package with the new pkgrel

greetings

@sl1pkn07 Are you having an issue building the package or is this a style thing?

sl1pkn07 commented on 2022-12-12 22:02 (UTC)

please add libjasper.so to depends istead of jasper

Getting

CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message):

Full build log: https://github.com/arch4edu/cactus/actions/runs/3385941390/jobs/5624699578

Also there are some outputs saying python2 is not found.

Updated to 3.4.16. Had to disable -Werror=address and build again ffmpeg 4.4

foxxy commented on 2022-05-18 11:53 (UTC)

New upstream doesn't build for me, so can't update the package. Fixes/Suggestions welcome.

Thanks @DrAtomic I've applied your patch to the package.
