Hi Rupak, can you update to a moderner Ubuntu? GNU Radio 3.8 should work with Ubuntu 16.04, indeed, but on 20.04, you can just
sudo apt install gnuradio gnuradio-dev cmake swig and have a working GNU Radio 3.8 development environment, eradicating so many sources of error... Anyway, did you implement that test? Also, when you run `ctest --output-on-failure` instead of `make test`, you should be getting a more detailed error report.
