find package with multiple names pacman

Question

Some packages like gcc-libs are apparently other packages, under a different name. turns out gcc-libs is just gcc: PKGBUILD

if I want to install that package, I know I can run pacman -S gcc-libs, but how can I find the original package, as in, the package which has a PKGBUILD named after it?

Answer 1

Those are called split packages (see PACKAGE SPLITTING section of PKGBUILD manual). I guess what you want is the pkgbase name and you can get that with pacinfo from pacutils e.g.

pacinfo lib32-gcc-libs

prints

Name:           lib32-gcc-libs
Base:           gcc
Repository:     core
.................................

so the Base: key means pkgbase name, in this case gcc
