roslaunch rpi_examples_indigo pi_in_rviz.launch [error]

[AlysonQ]

Hi , I get something wrong when roslaunch.
Would you help me to slove it ?
Here is the log shows. (screenshot >> https://goo.gl/oVZK0r)
I use raspberry pi 2 B+ and ROS indigo.
Sometimes it shows rviz segmentation fault.

Hi Alyson,

Something appears to be wrong with rviz, but based on this log I'm not
entirely sure what. Given that it is starting up at all it appears that it
is likely installed properly. Here are a couple of things to check off the
top of my head:

• Check the log file mentioned in the command line above and see if it
  gives you any clues: __log:=/home/ubuntu/.ros/log/
  b938b822-b811-11e5-befb-b827eb978b9e/rviz-4.log
• Check permissions. Look at the rviz app (/opt/ros/indigo/lib/rviz/rviz),
  the rviz file (/opt/ros/indigo/share/urdf_tutorial/urdf.rviz), and your
  own launch script and make sure all permissions line up properly. Goofy
  things can happen when things are not in sync. You could always try
  preceding roslaunch with sudo as a quick check.
• You could try temporarily removing or commenting out the rviz portion
  of the launch file and make sure the rest of it will run just as a sanity
  check to ensure nothing else is wrong with the installation.
• Try launching rviz by itself or using a demo of some sort to see if
  rviz will even startup on your machine. This will also help to see if
  there is something wrong with rviz itself. If it fails, check the log
  files in /home/ubuntu/.ros.
• I'm also just noticing that the user for this printout appears to be
  "ubuntu" (given that the home directory is in /home/ubuntu/). Just to make
  sure, this is running on a Raspberry Pi running Raspbian instead of some
  build of Ubuntu, correct? If I remember correctly, I believe the default
  user on a Raspberry Pi is "raspberry" (I haven't worked with one for
  several months now).

I hope this helps you find what is wrong.
