2013-03-09 05:47:59 -0500 | commented answer | Is cmvision a working package? @trinighost I am working in groovy, it seems like CvBridge.h is deprecated in this version and I was able to get rid of the error by using cv_bridge/cv_bridge.h. Of course, now I have other errors, but perhaps you will have more luck! |

2013-02-02 23:37:46 -0500 | commented answer | InvalidROSPkgException when running roswtf: no manifest file in roscpp You're right, re-running it several times seems to get rid of the problem! I still don't understand why the problem occurred in the first place, however :D |
2013-02-02 21:51:38 -0500 | asked a question | Error running rviz: Xlib: extension "NV-GLX" missing on display ":0.0" I cannot get rviz to start. I did They both run fine; when I run I get the following error (it tries 100x and gives me the same error that many times): My system: Ubuntu 12.10 32b, GeForce GT 630M, ROS Groovy. I am going to update this post with other info as described in http://www.ros.org/wiki/rviz/Troubleshooting#How_to_make_a_usable_bug_report, unless someone recognizes this problem right away. EDIT: Following the instructions in this answer http://answers.ros.org/question/10588/rviz-does-not-start-prints-glxunsupportedprivaterequest/?answer=15671#post-id-15671 got rid of the previous errors, now the rviz window opens up for a second and then crashes. I am getting: EDIT 2: Same as before, tried it a couple more times, now rviz window appears. No idea why. |
2013-02-02 04:53:25 -0500 | asked a question | InvalidROSPkgException when running roswtf: no manifest file in roscpp I am trying to run roswtf as described at the end of the http://www.ros.org/wiki/ROS/Tutorials/Getting%20started%20with%20roswtf (beginner tutorial), but it complains about roscpp not having a manifest file: What could be the cause of this?

2013-01-12 22:22:35 -0500 | commented answer | rosws problem fuerte @r0nald Thanks! It's good to know it's not necessary. I was afraid some tools would kick the bucket because they missed this var. |
2013-01-11 07:22:09 -0500 | commented answer | Beginner tutorials: segmentation fault with rospack depends1 @IsaacSaito Yep, I was following the github ticket and saw the fix...thanks a lot for your help! |
2013-01-10 06:52:14 -0500 | commented answer | rosws problem fuerte Even after executing this command, the $ROS_WORKSPACE is not set. I'm using Groovy under Ubuntu 12.10 32b. Any ideas why this happens? |
2013-01-10 06:50:16 -0500 | commented answer | rosws problem fuerte @r0nald Have you found out why $ROS_WORKSPACE was not set? I have the same problem (Groovy, Ubuntu 12.10 32b) |

2013-01-08 21:19:35 -0500 | commented question | Beginner tutorials: segmentation fault with rospack depends1 @IsaacSaito: Thanks a lot for your assistance! In the meantime I think I'll upgrade Ubuntu to Quantal and see if I can make some progress with that config. |
2013-01-08 19:32:11 -0500 | commented question | Beginner tutorials: segmentation fault with rospack depends1 @IsaacSaito As far as I can recall, it gives me a segfault even for existing ros packages, but I'll try again to make sure. I have no other custom packages -- this happened while creating my first package as part of the beginner tutorial! |

2013-01-07 05:39:24 -0500 | commented question | Beginner tutorials: segmentation fault with rospack depends1 @IsaacSaito I've posted my trace, seems like a python module gets stuck while detecting my Nvidia gfx card. Still not clear what to do. |
2013-01-07 05:32:15 -0500 | edited question | Beginner tutorials: segmentation fault with rospack depends1 I have created a package as described under /ROS/Tutorials/CreatingPackage, and everything seems ok. However, I get a segmentation fault when I try to see the dependencies with
Has anyone else encountered this problem? What might be the cause? My setup: Ubuntu 12.04 32 bit, ROS Groovy. EDIT: Debug trace, obtained by following @IsaacSaito's suggestion:
So it seems some python module chokes when detecting my Nvidia graphic card. I have a GeForce GT 630M, if that is relevant, and I have not installed yet any additional drivers except what Ubuntu installed by itself. I will try to see if updating the drivers will help, but seems like a weird dependency for ROS to get stuck on.
EDIT 3: My conclusion in Edit 2 was incorrect, I had made a mistake in checking the creation date for the /var/crash file. Nothing is generated there when I run rospack depends1. The (hopefully correct) trace now! Yes, kind of a Linux noob here... :-) (more) |
2013-01-06 21:47:23 -0500 | commented question | Beginner tutorials: segmentation fault with rospack depends1 @IsaacSaito I will post the trace when I get home today, thanks! |
