Hi! Sorry for my late reply. I preload libGLX_mesa.so.0 , and then run the code on the arm machine is ok. I tried to debug it, and then I found something different. The parameter of __glXLookupVendorByName is NVIDIA instead of mesa, it will dlopen libGLX_nvidia.so.0, but my Graphics Card is AMD, only IibGLX_mesa.so.0 can be found locally, so __glXLookupVendorByName failed.

If you could please shed some light on this topic, I would really appreciate it. Thank you in advance. BRs //Zongli
