Hi! Usage of dynamic libncurses is problematic in Firebird, as it not always match the versions available in Linux distributions.
Current FB 4.0-RC1 does not install in Ubuntu 18.04 LTS, which is not the latest, but still supported. I'm definitively not an expert on these libraries, but I tried to link it statically and still have editline working (build and test done in same system - Ubuntu 20.04). Official FB 4.0-RC1 isql depends on: libncurses.so.6 => /lib/x86_64-linux-gnu/libncurses.so.6 (0x00007fcd0995d000) With the attached patch, I avoided that dependency. Adriano
