Move_base failed to load when using gmapping_demo

Hi there,

I'm following this turtlebot tutorial . When I enter this command

roslaunch turtlebotnavigation gmappingdemo.launch

, process move_base keep dying with this error message

[ WARN] [1440147321.840796779]: Detected jump back in time. Clearing TF buffer.

[movebase-15] process has died [pid 3670, exit code -11, cmd /opt/ros/indigo/lib/movebase/movebase cmdvel:=navigationvelocitysmoother/rawcmdvel odom:=odom scan:=scan _name:=movebase _log:=/home/netbook/.ros/log/.../movebase-15.log].

When trying to trace the log files, I couldn't find the "movebase-15.log" there. It seems that the log file for movebase was not created.

Anyone knows how to fix this error? Thanks in advance for any help, I really appreciate it.

Edit: When trying to debug move_base with gdb, I got this text

There's something wrong with the threads, but I'm not able to figure it out. Thanks in advance for any help!

Cheers,

Hi, I have a similar problem when using Moveit! package. I am wondering if you were able to solve the problem or not?

Hi again,

It seems to be a bug in the ubuntu package update. I found the topic here https://bugs.launchpad.net/ubuntu/+source/gdb/+bug/952999

I modified the above file "/usr/share/gdb/auto-load/usr/lib/i386-linux-gnu/libstdc++.so.6.0.19-gdb.py" (as in gdb error, not the link) as #9 suggested:

Replace

     dir_ = os.path.join (os.path.dirname (objfile), dotdots, pythondir)

by

     dir_ = os.path.join (os.path.dirname (objfile), dotdots, dotdots, pythondir)

and it worked somehow.

Hope it helps!
