[KDE/Mac] Thoughts on standard directories in Qt5 - QStandardPaths

["Marko Käning"]

Hi David,

there has been quite some activity here on the list in the last while...
Not having taking part in discussions for so long makes it hard to respond
sensibly. :)

I had done all that earlier in [1], before Jeremy and I had discussed with Thiago.

In [2] I had stripped it down to only XDG_DATA_DIRS, because that's what we needed
for the CI system.

This allows the CI system to run its tests fine and with the run.sh [3] script 
I can also run KF5 apps on the console successfully, which does set XDG_DATA_DIRS
as required. (I am sorry, if this is redundant.)

Yes, that is possible and is done so. As discussed earlier MacPorts usually installs
the KDE executable app packages into /Applications/MacPorts/KDE/ ...

... without the need for env vars.

Jeremy has written earlier on this thread how it works on his kdesrc-build install.


Well, and as Jeremy pointed out, we can easily reintroduce those bits from the
Unix code which deal with XDG_CONFIG_DIRS.

Greets,
Marko
