libkexiv2 / gwenview does not build with current Exiv2 (hold untit Feb 7)

[Douglas R. Reno]

It seems that Exiv2's API changes have broken libkexiv2 (note that Gexiv in the GNOME land required a partial rewrite as well).

CMake Error at /usr/share/cmake-3.13/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find Exiv2: Found unsuitable version "..", but required is at
  least "0.24" (found /usr/lib/libexiv2.so)

5.0 Elasped Time - libkexiv2-18.12.0

Note that 18.12.1 does this as well.

Can we wait until gwenview-18.12.2 which is due February 7?

[Douglas R. Reno]

It looks like Pierre fixed this at r21068

[Pierre Labastie]

Sorry, hadn't seen the ticket. I stumbled upon this while trying to test KDE could be built with only Python 3. And I thought next release would be 19.04... I'll have to become more acquainted with the KDE release scheme...

Provides the dates for new releases. For the -dev book, I only plan on doing updates every three months or so.

[Pierre Labastie]

Thanks for the schedule. Don't know if the changes will be included in 18.12.2: they are in the master branch, but not the 18.12 branch.
