I reinstalled Nuitrack SDK because I had some issues related to low fps and I wanted to make sure that the SDK was working fine.
However, when I reinstalled Nuitrack, I had some problems when I did catkin_make to my package: an OpenCV exception, but I managed to fix this by adding again the path “/usr/local/lib/nuitrack” to $LD_LIBRARY_PATH and purging nuitrack and openni.
Now catkin_make builds “successfully” my package, but when I try to run my node, a Segmentation Fault happens, which is a very generic error, but I think that this is related to Nuitrack because before I reinstalled Nuitrack, it ran successfully.
I executed gcc -g to my .cpp file (node) to see when the segmentation error occurs, but it does not find “ros/ros.h” or any other header and this is very strange, because I think that the CMakeLists.txt is fine.
Do you know any way to solve this?
Note: The package which contains the node that does not run is almost identical to this one: https://github.com/shinselrobots/nuitrack_body_tracker
Also, before trying gdb, I flashed again the micro-SD card to see if reinstalling ubuntu again could solve the problem, but that’s not the case. Moreover, I cleaned and built other ROS packages which contains the same problem and the result is the same: Segmentation Fault.
This is the output of running bt (after gdb and r):

Which logname should I use? Because I don’t have any logname. I tried using my user name and it seems it worked well. I used ls -l to check if it worked:

By the way, I saw other posts in Nuitrack community and I checked for a folder that I think it’s related to the logname, which name starts with “e24” and I don’t have it (maybe I deleted it by mistake when I uninstalled Nuitrack for the first time, I don’t know…).
I tried standard samples and they work, but after a moment of working, the image display freezes and it says “Please get a license”.
Note: I also tried running ld in my program and the output is Segmentation Fault.
It seems that the issue is connected to the license activation. Without any license, Nuitrack works for 2-3 seconds. We would recommend you to check Nuitrack by activating Trial License first. You can generate it in your personal account. Please follow the instructions below:
I followed your instructions (the option Nuitrack Trial), but nuitrack_license_tool fails in the last step. The compatibility test succeeds, but when I introduce the license and click activate, the following error occurs:
