nomacs-qt6-git have been prematurely deleted but can be still found at https://github.com/FabioLolix/PKGBUILD-AUR_fix/blob/master/n/nomacs-qt6-git/PKGBUILD

• Pkgbuild maintained at https://github.com/FabioLolix/PKGBUILD-AUR_fix

• every time you have error while loading shared libraries: libXXX.so.XXX: cannot open shared object file: No such file or directory for build from source programs you have to rebuild it

Another package goes to the ignore list - opencv. Upgrading it to the latest v4.8.0 causes nomacs to not open when I click an image anymore. Downgrading it to 4.7.0 fixes that.

@rado84 you need rebuild the package not to hold back other packages, it is the same every time a dinamically linked soname changes

$ nomacs
nomacs: error while loading shared libraries: libopencv_imgproc.so.407: cannot open shared object file: No such file or directory

• implement checkrebuild from rebuild-detector into your workflow.

@microcoder you have at least one package that is build against and old icu version (76), current is 78, rcc beling to qt6-base

$ pkgfile /usr/lib/qt6/rcc
extra/qt6-base

Pinned comment updated

@abouvier yes, it was removed by accident

You're not supposed to remove the epoch once defined.

As I made a PR with fixes https://github.com/nomacs/nomacs/pull/1290 updated PKGBUILD with -DENABLE_HEIF=ON fixes

It looks like the update removed git-lfs from makedepends, but this is still required to build.

@kinoe rebuilding with devtools works fine, launch fine
