How to export DBUS_SESSION_BUS_ADDRESS

Question

I\'m trying to run D-Bus on an embedded system (Yocto Linux) and connect to it from my application code.

I get the following error when I call dbus_bus_get(DBUS_BU

Answer 1

pid_gnome=$(pgrep gnome-session)
DBUS_SESSION_BUS_ADDRESS=$(grep -z DBUS_SESSION_BUS_ADDRESS /proc/${pid_gnome}/environ|cut -d= -f2-)
export DBUS_SESSION_BUS_ADDRESS=${DBUS_SESSION_BUS_ADDRESS}

Please make sure that the user has the DISPLAY variable set.

Another alternative is:

export $(dbus-launch)
