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