Hello,

I removed rviz from ros-groovy

$ sudo apt-get remove ros-groovy-rviz

After that from backup i coppied rviz folder into /opt/ros/groovy/share then

$ rosdep install rviz

$ rosmake rviz

rosdep and rosmake doesn't give any error. After that when i tried

rosrun rviz rviz

It is giving following error:

pr2admin@basestation:~$ rosrun rviz rviz

[rosrun] Couldn't find executable named rviz below /opt/ros/groovy/share/rviz

[rosrun] Found the following, but they're either not files,

[rosrun] or not executable:

[rosrun]   /opt/ros/groovy/share/rviz

rm ~/.rviz/* ...it didnot remove the error

Do i need to delete rviz configuration file? rm ~/.rviz/*

Hi everyone, I updated rviz on ros groovy since then while adding camera topic, rviz is getting closed and it is giving Segmentation fault (core dumped) on terminal window. I am working on pr2 robot.

I am stuck at this problem, Please help me to fix this.

Hi Albert, We are trying the same thing to replace pr2_controllers_msgs by control_msgs. But we are facing the same issue as mentioned in this post. We tried to look at your modified code, but we are not able to locate/download your file. Kindly share it again or mail at nikhil.mm@tataelxsi.co.in

When we use catkin_init_workspace command, it is showing following error

without sudo:

catkin_init_workspace
Could neither symlink nor copy file "/opt/ros/groovy/share/catkin/cmake/toplevel.cmake" to "/home/pr2admin/r_os/src/CMakeLists.txt":
- [Errno 13] Permission denied
- [Errno 13] Permission denied: '/home/pr2admin/r_os/src/CMakeLists.txt'
pr2admin@c1:~/r_os/src$

with sudo:

sudo catkin_init_workspace
Traceback (most recent call last):
  File "/opt/ros/groovy/bin/catkin_init_workspace", line 11, in <module>
    from catkin.init_workspace import init_workspace

Kindly help us to resolve this problem
