Sudo

If you're working on language data, sudo is pretty much only for running package managers like apt (or port or dnf) and for running package setup scripts like https://apertium.projectjj.com/apt/install-nightly.sh

In general, don't use sudo (and don't run as the root user) when building/compiling things

The only exception is sudo make install, but when working on language data you should never have to do this.

But if you work on your own computer, a possibility is to allow the instalation directory (generally /usr/local/share) a write access from your account (using chown, chgrp or chmod with sudo), and then, you will not have to use sudo any more for compiling a language pair.
