I got this issue also. But I don’t know how it’s solved in below link.

Can you help to direct me to the right channel or way to fix the issue?

Seems you use the libByteTracker.so. We have the guide for customize the low level tracker library: Gst-nvtracker — DeepStream documentation. We also released the nvtracker plugin code here: /opt/nvidia/deepstream/deepstream-7.1/sources/gst-plugins/gst-nvtracker/. You can debug the fail with those source code.

OK, it seems all end up here.

Suggest to use Weak Symbols in Dynamic Linking, which is comparatively easier to maintain
