I usually run Ubuntu or Debian servers, but I like Arch Linux a lot. So when I need to compile software in Arch Linux, I come to the question of what is the equivalent of build-essential package in Arch Linux.
The package build-essential is a set of packages that you need in order the compile software in Ubuntu or Debian. For Arch Linux run this command.
sudo pacman -Sy base-devel
Choose the default option, and you are good to go.
