hplip 3.15+ supports python 3. Could we reflect that in the ebuild? I've made a proof of concept at https://github.com/hsoft/personal-overlay/blob/fc990501b227a07b6903dd39425205935a0d7751/net-print/hplip/hplip-3.15.6.ebuild The ebuild is the same as in Gentoo's repo, except for the "python3_4" addition in PYTHON_COMPAT and the dependency change for pyobject (we have to depend on pyobject2 if we're under python 2 and pyobject3 if we're under python 3). The result seems to work on my machine. Reproducible: Always
Until now I did not add python3 support because not all dependencies did support python3. This seems to have changed but there is still notify-python which has no python3 support. Did you test with qt4 use flag enabled as this will pull in notify-python.
I don't use the qt4 ui, no, so I didn't try it. python-notify doesn't look like it's ever going to be updated for python 3, so if we wait for that, we're in for a long wait. It looks like a stale lib. Since it's an optional dependency, can we simply make the "libnotify" flag mutually exclusive with python 3?
Fixed in Git. Thanks for the report. I dropped the dependency on notify-python. Notifications are still there but not that beautiful.
