The first one will build and install it (root needed) and the second one will build it for packaging (which is later installed as root). I'm new to Arch too but I think the way AUR used to work is it used to build as root so it could install directly like that. Which may indicate out of date PKGBUILDs. These days though the second one is more common because you build as non-root into $pkgdir then later install into /usr as root via pacman.

One, is the more frequent `./configure --prefix=/usr` and the other is `./configure --prefix=$pkgdir/usr`. I was wondering if one is more correct than the other? Are there any downsides to using the second one? Thanks, Jashandeep Sohi References 1. https://cloudmagic.com/k/d/mailapp?ct=pa&cv=6.0.6.1&pv=4.4.2 2. mailto:jashandeep.s.sohi@gmail.com
