我正在尝试在嵌入式系统(Yocto Linux)上运行D-Bus,并从我的应用程序代码连接到它.
我打电话时收到以下错误 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
我意识到我需要启动第dbus-daemon一个,所以我从命令行运行dbus-launch.这打印出一个值,DBUS_SESSION_BUS_ADDRESS但我怎么能以编程方式导出它？
谢谢您的帮助
