Dyalog Forums

Dyalog 17.1 and earlier should run on Raspberry Pi OS Buster. However, if you see the following error when starting Dyalog
/opt/mdyalog/17.1/32/unicode/dyalog: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory

sudo apt install libncurses5
