You have two find_package(Gnuradio "3.9" ...) in your CMakeLists.txt - lines 77 and 177 https://github.com/apruhd/gr-TFMv3/blob/master/CMakeLists.txt#L77 https://github.com/apruhd/gr-TFMv3/blob/master/CMakeLists.txt#L177 You need to add the required components (digital, blocks, analog, ...) on line 77 and delete line 177 Regards, Vasil
