问题描述
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.
I'm trying to run D-Bus on an embedded system (Yocto Linux) and connect to it from my application code.
调用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
我意识到我需要首先启动dbus-daemon，所以我已经从命令行运行了dbus-launch.这样会打印出DBUS_SESSION_BUS_ADDRESS的值，但是我该如何以编程方式将其导出?
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?
感谢您的帮助
推荐答案
