Sad, that rules out my first guess!But I just realized that this tutorial is for GNU Radio 3.8, which you don't have if you've got a fresh Manjaro installation! Yay! (There's a small warning in the beginning of that page, but it could be more prominent.)
So, maybe rather follow the official C++ guide from the GNU Radio academy on https://tutorials.gnuradio.org.
That guide is a bit better illustrated and actually tested with modern GNU Radio :) and can be found under:

I was using only one version of Gnuradio - it was fresh install of GR on Manjaro(newest one).
