DBUS_SESSION_BUS_ADDRESS will be used by libdbus, which is in turn used by QtDBus which is then used by KLauncher.

Try running: export $DBUS_SESSION_BUS_ADDRESS right after the eval 'dbus-lau...' line.

"export $DBUS_SESSION_BUS_ADDRESS" raises an error: "not a valid identifier". I've tried the following:

Code: Select all

export DBUS_SESSION_BUS_ADDRESS=${DBUS_SESSION_BUS_ADDRESS}

But I still have the Dbus error. I'll see if I can create a dbus connection with a sample program...

Oops. It was supposed to be:

Code: Select all

export DBUS_SESSION_BUS_ADDRESS

You can use "qdbus" for testing.

Qt comes with a dbus sample project called "dbus-chat". I start the dbus daemon:

Code: Select all

$ dbus-daemon --config-file="${INSTALL_DIR}/share/dbus-1/session.conf" &
[1] 813
$ echo $DBUS_SESSION_BUS_ADDRESS
(noting outputted !!)
$ dbus-chat
Cannot connect to the D-Bus session bus.
Please check your system settings and try again.


This sounds like bad news. But then, I try this:

Code: Select all

dbus-launch --exit-with-session --config-file="${INSTALL_DIR}/share/dbus-1/session.conf" dbus-chat


And it works ! But starting krita or kdeinit4 the same way doesn't.

Oops. It was supposed to be:

Still the same "No DBUS session-bus found." error.

You can use "qdbus" for testing.

Thanks! There is also another app: "qdbusviewer". When I run it, I have this error:

Code: Select all

Error: Cannot connect to D-Bus: /Library/koffice/libdbus/dbus/bin/dbus-launch terminated abnormally with the following error: EOF in dbus-launch reading address from bus daemon

I have the same error with qdbus.

So now it sounds like a configuration problem.

Unfortunately I do not know why this is occurring. Possibly you may need a patched copy of libdbus which is usable on Mac.

Thanks a lot for all your help. I *think* there are a few adjustments I need to make in libdbus...

I was wondering, does kdeinit4 needs both a system and session dbus daemon ? Until now I was launching only the session one. And as for now the system daemon won't run, but I'll try to fix that if it is required.

It shouldn't need the system bus, as access to the system bus is not usually permitted from user applications.
