I'm trying to follow the instructions in
https://github.com/flok99/multitail/blob/master/INSTALL
It says to install the "ncursesw development libraries"
How do I do that?
It depends on your distro:
On Debian/Ubuntu, sudo apt-get install libncursesw5-dev
On RedHat/Fedora/CentOS, sudo yum install ncurses-devel
