I'm trying to run super point model with Vitis-AI in the ZCU102 board. However, I'm getting the following error when try to cross-compile it using the build.sh script. I'm using Ubuntu 20.04 and Vitis-AI 3.0.

I think this error happens due to a linking issue. Any help would be highly appreciated

I was able to solve this issue by changing the Makefile

Add the following compiler flag to the Makefile

LD_FLAGS += -lvart-util

Further, this issue exists for HFNet too. That Makefile should also do this change to resolve this problem.
