Hello, I’m a bit new to advanced linux and programming stuffs… Can someone explain me why compiling exists and what this process does and how to do it in the principals situations (I’ve heard that you can use the “makepkg” command). Thx to everyone who replied.

      humm… ok, and for example when you have the binaries of a file you have to compile it a last time, no? That’s my experience with aur, when you get the bin, you have to makepkg a other time

        The Arch Linux makepkg is a bash script with description

        make packages compatible for use with pacman

        Some packages of AUR are not about compiling but fetching the binary (sometimes converting it from deb) and then prepare it for you so you can install it. So when you use AUR to install a binary package instead of compiling there is really no compiling involved afair.

    Some software is brand new and not yet packaged as software packages. And for already existing software Linux distributions will have to make choices as not everything can be included and maintained. Now if a developer creates new software, and things are not packaged yet (With Debian for Debian stable this can take a really long time) it can be comfortable for the developer to provide just instructions about how to compile the software so users can run the software, while the maintainer does not have to bother about packaging.

      So it’s a bit like taking all the useful packages and mix it up in a clean package? And are .deb .rpm… packages made like that?

        Yes, indeed. If you would want to you can re-compile Debian deb packages from Debian sources. To give you an idea : https://wiki.debian.org/apt-src There’s also Gentoo Linux which has a history of compiling software. Years ago that was interesting because of flags for compiling, make the resulting software optimized for certain CPU models.

    Compiling code converts it from human readable source code into optimized machine code which the processor understands how to execute. For a lot of software you can just unpack the source code, run ./configure, run ‘make’, and then ‘make install’. This can vary a lot and is a simplified explanation, but it’s a start…
