ROS在QT环境下编译 报错如下

FATAL] [1578224064.647733042]: ROS_MASTER_URI is not defined in the environment. Either type the following or (preferrably) add this to your ~/.bashrc file in order set up your local machine as a ROS master:

export ROS_MASTER_URI=http://localhost:11311

then, type ‘roscore’ in another shell to actually launch the master program.

解决方案

这个属于环境搭建问题
图片: 点击“Edit”，在 变量 处输入ROS_MASTER_URI，在 值 处输入 http://localhost:11311，再次编译即可。
