How to export DBUS_SESSION_BUS_ADDRESS

由 ↘锁芯ラ 提交于 2019-12-31 16:48:46
问题 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_BUS_SESSION, &err); Using X11 for dbus-daemon autolaunch was disabled at compile time, set your DBUS_SESSION_BUS_ADDRESS instead I realize that I need to start the dbus-daemon first so I have run dbus-launch from the command line. This prints out a value of DBUS_SESSION_BUS_ADDRESS but how could I export it programmatically? Thanks for
