#!/usr/bin/env sh

# Statically compile nnn with netbsd-curses, musl-fts and musl libc on Ubuntu
#
# netbsd-curses: https://github.com/sabotage-linux/netbsd-curses
# musl-fts: https://github.com/void-linux/musl-fts
# musl libc: https://www.musl-libc.org/
#
# Dependencies: git
#
# Usage: musl-static-ubuntu.sh [no_run]
#        # optional argument - do not to execute the binary after compilation
#
# Notes:
#   - run the script within the top-level nnn directory
#   - installs musl & gits netbsd-curses, musl-fts libs
#
# Tested on Ubuntu 20.04 x86_64
