[Albert950207]

Does anyone know what happened ?

Thanks!

Hi @Albert950207,

Please try to execute the nuitrack_sample application and send us the output.

[Albert950207]

Hi @VadimAspirin

Thank you for your replying. Where is nuitrack_sample application is ?

[VadimAspirin]

@Albert950207 , you can run nuitrack_sample from the command line as the nuitrack application (just in case: /usr/bin/nuitrack_sample).

[Albert950207]

@VadimAspirin I run nuitrack_sample from the command line and I get this error:
nuitrack_sample: error while loading shared libraries: libglut.so.3: cannot open shared object file: No such file or directory

[VadimAspirin]

@Albert950207 please try to install freeglut3 and libbluetooth3 packages and execute the nuitrack app again: apt install freeglut3 libbluetooth3

[Albert950207]

@VadimAspirin I have installed freeglut3 and libbluetooth3 but after I run nuitrack_sample, I just get a flash of this application and then still get the error:

[VadimAspirin]

@Albert950207, please advise, what Nuitrack version and RGBD-sensor model do you use?

[VadimAspirin]

If you execute nuitrack_device_api_sample and post the output here it will be very helpful too.

[Albert950207]

@VadimAspirin My RGBD-sensor is intel D435i and I dont know what my version of Nuitrack is but it could be the latest one because I just download it from repository of installation Nuitrack. I dont know how to check the version because I cant run nuitrack, nuitrack_sample or even nuitrack_device_api_sample. All of them give me an same error: Segmentation fault.

Btw, I install and run nuitrack in my Windows operating system with same computer and same RGBD-sensor but when I run some samples in nuitrack I got error code 2. I check it on google and google told me that I need to make my intel sensor connected as usb 3.2(mine is 2.1). Can nuitrack work when intel sensor connected as usb 2.1?

[VadimAspirin]

@Albert950207, Nuitrack only supports Intel Realsense sensors when Intel Realsense is connected to USB 3 (as Intel recommends).

@VadimAspirin I have the same problem on Ubuntu 20.04 . I opened this issue back in May as well but no solution as of yet? I get a segmentation fault when running nuitrack, nuitrack_sample or even nuitrack_device_api_sample. I'm using the latest download.

Hi @jimruxton, if I understood correctly this is your issue on the Nuitrack community forum? According to the information I have, removing libSenDuck.so from the /usr/local/lib/nuitrack/OpenNI2/Drivers/ folder helped solve your segmentation fault.

[jimruxton]

Yes this is correct. It appears |libSenDuck.so |was causing the segmentation fault. Removing this driver fixed it. | |
