Have built the Angstrom master for a Beaglebone.
Trying to create a simple systemd service (non-forking).
This fails to start.
When I look into the systemd log (log_level=debug),
there are references to "/org/freedesktop/systemd1"
which does not exist.
Over the Rainbow <http://www.bbc.co.uk/programmes/b03bvnf9>
Instead "/run/systemd" exist, which I believe
is present in newer systemd's.
The service uses the boost, curl, curlpp and thread libraries.
Uses UDP and serial port for communication.
I do not use D-Bus directly, but it seems to be related to D-Bus anyway.
Anyone got a clue on how to proceed?
Had another look, and I was barking up the wrong tree.
/usr/share/dbus-1/services contains org.freedesktop.systemd1.service
My app dies when I do
getenv("HOME");
When I define
User=root
Group=root
the nodeserver.service it starts without problem.
Sorry to bother.
