Well, looks like the opencv version in EL7 (2.4.5) will only support digikam 4.0.0 (4.1.0 requires 2.4.9.  Perhaps we should should just push the 4.0.0 build.

Needs libpgf too. baloo, kfilemetadata-devel and qtsoap-devel appear to be optional.

Am now trying with hack to accept opencv 2.4.5 - http://copr-fe.cloud.fedoraproject.org/coprs/orion/digikam/build/78983/

Builds okay with the opencv hack:

https://copr-be.cloud.fedoraproject.org/results/orion/digikam/epel-7-x86_64/digikam-4.7.0-2.fc23/

It doesn't build the dlnaexport kipi plugin due to missing deps.

Looks like qtsoap was ready to go, just not built, so we'll be able to enable that.

Created attachment 995350 [details]
patch for epel support

Current proposed patch to spec.

Rex - any comments?  I think you'll end up needing to have a version in your kde4 epel7 copr as well built with some of the newer libraries in there.

thanks for the reminder, I'll try to work on this tomorrow.

digikam-4.10.0-4.el7 has been submitted as an update for Fedora EPEL 7.
https://admin.fedoraproject.org/updates/digikam-4.10.0-4.el7

digikam-4.10.0-4.el7 has been pushed to the Fedora EPEL 7 testing repository.

There is one problem with digikam on epel7 testing.

package: kipi-plugins-4.10.0-4.el7.x86_64 from epel-testing
  unresolved deps: 
     hugin-base

hugin is not available on epel7/rhel7.

digikam-4.10.0-5.el7 has been pushed to the Fedora EPEL 7 testing repository.

hugin appears to also need lensfun and libpano13 which are also missing.

digikam-4.10.0-5.el7 has been pushed to the Fedora EPEL 7 stable repository.
