Problem with Laser Scanner hokuyo URG-04LX-UG01 in ROS hydro
Hi,
I want to run a laser scanner in ROS hydro. First of all I can connect to laser via hokuyo_node. But when I want to visit output data with RVIS, I can't! when I add laserscanner and change topic to scan , status changes to error. And also I try to log data with "rosbag record -O name /scan". But unfortunately I faced to this error:
/opt/ros/hydro/lib/rosbag/record: symbol lookup error: /opt/ros/hydro/lib/librosbag.so: undefined symbol: _ZN3ros7console5printEPNS0_10FilterBaseEPN7log4cxx6LoggerENS0_6levels5LevelEPKciS9_S9_z
I try: "apt-get update" and "apt-get upgrade"
but it doesn't work yet! What can I do now?
Thanks.
What does "doesn't work" mean exactly? What errors do you get for apt-get and when you set the laser display in rviz?
The error that you see might be fixable with apt-get upgrade.
I meant that even after upgrade, rosbag doesn't work. But now I can solve problem with rosbag by another solution in this link "http://answers.ros.org/question/123421/hydro-kinect-ubuntu-1204-library-issue/" I run roscore and then hokuyo_node and then rvis and I set laser scanner and topic scan.
