Hello, all.

When I tried to launch the openni_camera with the command "roslaunch openni_camera openni_node.launch", I got weird errors.

===================================================================================
[openni_node1-1] process has died [pid 8338, exit code -11].
log files: /home/enddl22/.ros/log/d7cb5b9c-42ef-11e0-9bb4-d8d3857b0f6f/openni_node1-1*.log
===================================================================================

And roswtf said that

===================================================================================
ERROR Could not contact the following nodes:
 * /openni_node1

ERROR Errors connecting to the following services:
 * service [/openni_node1/get_loggers] appears to be malfunctioning: Unable to communicate with service [/openni_node1/get_loggers], address [rosrpc://BEE-PG-46634:60728]
 * service [/openni_node1/set_logger_level] appears to be malfunctioning: Unable to communicate with service [/openni_node1/set_logger_level], address [rosrpc://BEE-PG-46634:60728]

===================================================================================

I have diamondback and cturtle ROS packages and properly switched to diamondback using "source ./setup.bash" command.

Any comments could help me a lot.

Cheers

Actually it seems, this is depending on your PC hardware. I had the same problem, when trying to run openni_camera on a Pentium 4. On several newer computers Core 2 or Core i5 everything runs fine.

In any case, while the OpenNI stuff is compiled using only SSE2, the NITE libs seem to be compiled for newer CPUs (maybe using SSE3 instructions) and will cause "illegal instruction" errors on older machines.

I'm not sure if this is the solution to the problems on this thread, but here is how I got openni_camera to compile and work on an older machine that does not have the newer SSE3 requirement that is built into the Diamondback Debian packages and even the CMakeLists.txt file for openni_camera when you download the source. As you can see from the following thread, the trick is to compile openni_camera with only SSE2 support:

I am having the very similar problem with "roslaunch openni_camera openni_node.launch" under diamondback.

In my case, I had to install unstable version and the following command [this was on cturtle about 2 months ago] its better to use stable versions than unstable.

roslaunch openni_camera openni_kinect.launch

worked perfectly

What exactly do you mean with unstable version? I just installed unstable, but there is no openni_kinect.launch launchfile. Did you install ni or openni_kinect?

tom: sry, I should have mentioned that this was on cturtle a while ago (about 2 months), I installed ni stack. no openni_kinect.launch file means did you check the folder manually? it's possible ROS_PACKAGE_PATH settings are not right. whats the output for "rospack find openni_camera" ?

blueskin ( 2011-03-10 02:39:21 -0500 )edit

ROS_PACKAGE_PATH is set correctly. There is no openni_kinect.launch in newer versions of openni_camera. I installed Diamondback from source 2 weeks ago and everything run perfectly. Then I reinstalled ROS around Monday and am struggling with this. Hope someone can point me in the right direction.

tom ( 2011-03-10 03:15:39 -0500 )edit

with diamondback it should be "roslaunch openni_camera openni_node.launch" , I know that's what you tried. I don't know how to fix it then, maybe try rebooting the system

Did you consider using the new debian package for kinect? here

I've tried that, also installing Diamondback and unstable binaries, building diamondback, ni and openni_kinect from source, reinstalling nite drivers and installing different versions of ROS packages. The last working sources were Diamondback pre-release, but I cannot achieve that now. Cturtle works

tom ( 2011-03-10 17:28:04 -0500 )edit

As I wrote above, I tried the same on *various* machines and had the error described in the question above only on an old pentium 4. regardless whether using the diamonback debian packages or a version actually compiled from the sources on that machine. My guess would still be some CPU instruction set problem

Georg ( 2011-03-11 00:07:23 -0500 )edit

This sounds reasonable, probably some library (may well be NITE) in the newest version does not speak the language of my AMD Sempron 3100+ Pentium 4. I'll try building NITE from source, hopefully it's straightforward to install then... or buying a new computer, at least I'll be able to play SC2 :).
