How to output ROS_ERROR to log file in ros Indigo version
Hi,I'm going to output the ROS_INFO,ROS_WARN,ROS_ERROR,ROS_FATAL infomation to log file ,so I set output="log" in launch file,but I found that only ROS_INFO and ROS_WARN information was written to the log file,ROS_ERROR and ROS_FATAL information did not exis. I'm using ros indigo version, does anyone encounter this problem? Thx a lot
