The only one way I found so far to install correctly WSJT-Z on Raspberry Pi is quite way around. I was unable to installt on Bookwarm. Recently I found out that I can do it installign on Raspberry 5 Ubuntu Dragon OS – it is a spcial distribution for Hams.
The only one glitch was that I was unable to install WSJTX – it failed after command cmake ../wsjtx
The solution was:
sudo add-apt-repository universe && sudo apt update && sudo apt install asciidoc
To install it I used manual which is available HERE.
Good luck, as it is a pain in the bottom 馃檪
