how to change the vtable symbol to a global symbol?

Question

I have compiled a so file（libarfoundation_core.so） which has a base class ARSRGpuFilter, and a other so file which need dependency the compiled so file could not compiled because " undefined reference to `vtable for cameralink::ARSRGpuFilter'"

Then, I find the vtable symbol of the ARSRGpuFilter is a Local Symbol, so how to change the vtable symbol of ARSRGpuFilter to a global symbol?

Please show a [mre]. You probably have an undefined virtual method in the class — Alan Birtles, Mar 15 '22 at 06:49
