Issue after running roslaunch

[andrewraharjo]

Got an issue after successfully compiling camera_base and flea3 catkin_ws. FlyCap 2.9.3.43 Running Ubuntu 14.04 ROS Indigo. Any idea with what's going on ?

[pg_14354944-2] process has died [pid 6529, exit code -11, cmd /home/dev-box/catkin_ws/devel/lib/flea3/flea3_single_node __name:=pg_14354944 __log:=/home/dev-box/.ros/log/d9e8303c-1e1a-11e7-95ae-ec086b69f415/pg_14354944-2.log].

Try upgrading to flycapture sdk 2.10, or whichever latest one from their website.

[andrewraharjo]

I don't think that would be the issue. The 2.9 running fine with pointgrey_driver from clearpath. When I did rostopic list it gives me all the publish node. Only when I echo them all empty

[versatran01]

Which one is giving you empty messages?

[andrewraharjo]

@versatran01 /pg_14354944/image_raw Oh by the way Chao the camera model is Grasshopper3 23S6C model.

[versatran01]

I'm still suspecting this is an issue with the flycapture sdk.

[andrewraharjo]

Chao, I'll give a shot to reinstall the Flycap SDK. Also the available SDK is 2.9 for 14.04. Are you still considering use 2.10 instead ?

[kartikmohta]

exit code -11 usually means a segfault, can you run the node under gdb (See http://wiki.ros.org/roslaunch/Tutorials/Roslaunch%20Nodes%20in%20Valgrind%20or%20GDB) and paste a stacktrace?

[andrewraharjo]

UPDATE:

So I did follow Chao suggestion on updating the FlyCap to 2.9.3.43 and still got exit code -11.

Also my linux kernel is 4.2.0-27 Do I need to upgrade the kernel ? Linux control 4.2.0-27-generic #32~14.04.1-Ubuntu SMP Fri Jan 22 15:32:26 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

[kartikmohta]

Can you paste the backtrace from gdb after typing bt in gdb after the crash.

[versatran01]

Why is it in /opt/ros/indigo/lib/libflycapture.so.2? Is it still using some lib that comes with ros?

[kartikmohta]

@versatran01 The ROS pointgrey_camera_driver installs it there if it's not already installed.

[versatran01]

So this could be a problem then?

[andrewraharjo]

@kartikmohta yes you're correct the pointgrey_camera_driver is installed. I also have Blackfly connected through GigE port. Eventually we want to use both of them.

[versatran01]

So flea3 is linking to that lib that comes with ros. Maybe try force it to link to the one you installed.

[andrewraharjo]

@versatran01 Chao, where do you link that ? Is it in your flea3/flycapture/lib/? I think the question is more into which file does call /opt/ros/indigo/lib/libflycapture.so.2 ?

[versatran01]

the FindFlycapture2.cmake is supposed to find the one in flea3/flycapture/lib. Just for testing, you can link directly to the one in flea3 and see if still gives an error.

Hello, I have got the same issue than andrewraharjo using FlyCap 2.9.3.43 Running Ubuntu 14.04 ROS Indigo and the camera GS3 U3 60QS6C, however I only have one installation of flycap in my computer with the lib saved in usr/lib (no supplementary installation of flycap with ros). FindFlycapture2.cmake looks for the library in usr/lib, yet I got the exit code -11. Did direct link to the lib in flea3 solve the problem ? Do you have any other idea on this issue ?
