💖 AUTOBUILDREQUIRES(1) 💖

okay so bestie, this is a page from the User Contributed Perl Documentation section, and it's about a little tool called autobuildrequires that does your homework for you. no cap. 🎀

✨ NAME ✨

autobuildrequires — figure out the BuildRequires of an RPM build, automatically, like magic 🪄

🌸 SYNOPSIS 🌸

auto-br-rpmbuild -ba foo.spec

auto-br [build-command ...]

that's it. that's the whole vibe. 🦋

💅 DESCRIPTION 💅

So Autobuildrequires looks at an RPM package build and works out which BuildRequires lines it actually needs. it's giving detective energy 🔍✨

Instead of running rpmbuild like a normal person, you run this instead:

auto-br-rpmbuild -ba foo.spec

(and yes, all the usual rpmbuild flags are supported, so you don't have to unlearn anything 💖). The command builds your package, and then it prints out a list of BuildRequires lines that it thinks your package needs. iconic behaviour honestly 👑

Now — if your build command is more complicated and/or it doesn't use rpmbuild at all, then use this instead:

auto-br [build-command ...]

For example:

auto-br make

look at her go 🏃♀️💨

🧚 HOW IT WORKS 🧚

okay this is the part where it gets lowkey genius. the basic "magic" is a C LD_PRELOAD module called auto-buildrequires-preload.c, and what it does is intercept some system calls to figure out which files the build is looking at 👀. those get logged to a simple text file. so it's basically a little spy camera for file access, but make it legal 🕵️♀️💖

Then the Perl analysis script, auto-br-analyze.pl, runs afterwards on that logfile, and it uses rpm to find out which packages those files belong to. Those get printed out as your list of BuildRequires. slay 💅

And a shell script, auto-br, brings the whole thing together. she's the main character holding the group project together fr fr 🫶

🔥 EXIT STATUS 🔥

This program returns 0 if it worked, or non-zero if there was an error. no in-between, bestie. 💀
