[Discuss-gnuradio] Installation of gr-radar

Hi

I am installing GNU gr-radar in Ubuntu. I installed all dependencies and now while in step of making build of gr-radar by command 'make' I am getting below mentioned error Though I upgraded QT to latest version which is "Using Qt version 5.7.1 in /usr/lib/arm-linux-gnueabih". I read in Issue#16 that you should use QT6 but I am unable to find any stable version of QT6 or how to install that.

Error:
