Hi I experience the same runtime error "Failed to load nodelet". In my case with:

• Ubuntu 20.04
• Kernel 5.8.0-50
• Spinnaker 2.3.0.77
• ROS Noetic
• Camera BlackFly S, GigE

the utility spinview works correctly.

Have you fixed it somehow @tiexuedanxin @kylelscott @eleathers ?

Any idea ?

Thanks

@andreucm ,

I was able to get it working by reverting back to SDK Version 2.0.0.146.

However, when using Ubuntu 20.04, I cannot get SpinView to work with both SDK versions 2.3.0.77 or 2.0.0.146.

ok! thanks @eleathers !

I identified the crashing line: system_(Spinnaker::System::GetInstance())

However, FLIR testing program "/opt/spinnaker/src/Acquisition/Acquisition.cpp" also calls GetInstance in a quite different way: SystemPtr system = System::GetInstance(); In my case , FLIR test Acquisition program runs ok.

I'm going to modify the code to check this hypothesis....

Any further idea ?

Running: roslaunch spinnaker_camera_driver test_spinnaker.launch

also crashes at this line: Spinnaker::SystemPtr system = Spinnaker::System::GetInstance();

So it seems that we have some ld runtime issue. I want to stress that /opt/spinnaker/src/Acquisition/Acquisition.cpp works ok.

Any further idea ?

thanks

Andreu
