Hello Martin,

thanks for quick response.

Got it. It won't be so easy though. I'm not going to go off-topic on
this list, just FYI:

Apparently XDG_DATA_DIRS is used as search path for dbus services[1].
Turns out I've set it correctly but not in correct place. It needs to
be set somewhere where user systemd instance started by login manager
picks it up, because it seems it also starts the session dbus. I've put
it in ~/.config/environment.d/local.conf. Now "systemctl --user show-
environment" shows it is set (though now my shell doesn't see it).
However, after I run Evolution, system installed Evolution services are
still picked over the local ones. I even rebooted system to make sure
everything is properly restarted.

I think I'll go with system packaged Evolution for now and troubleshoot
it again when I have time to study and hack Evolution source again.

Thank you!

[Evolution-hackers] Automatically start services from install path

[Marek Howard via evolution-hackers]

Hello,

I'm running Evolution from source. The wiki page about building[1]
suggests to run compiled evolution like this:

   $ source $HOME/sources/build
   $ $PREFIX/libexec/evolution-source-registry &
   $ sleep 1
   $ $PREFIX/libexec/evolution-calendar-factory -r &
   $ sleep 1
   $ $PREFIX/libexec/evolution-addressbook-factory -r &
   $ sleep 1
   $ $PREFIX/bin/evolution

The relevant variables for running evolution defined in build
environment file I have defined in shell startup file, so my script for
running evolution currently does what follows after the source line.

Is there any way to build evolution to make it automatically start the
required services from correct installed path on startup, just like the
system installed Evolution does?

When I just invoke 'evolution' from ~/local/bin/evolution, it starts up
system installed Evolution services from /usr/lib instead those that
are installed in default* prefix subdirectory ~/local/libexec. I keep
Evolution distribution package installed just in case the development
version breaks.

* I pass -DCMAKE_INSTALL_PREFIX=$HOME/local to all source modules, i.e.
evolution, evolution-data-server and evolution-ews.

Thank you!
