Multilib
Related articles
The multilib repository is an official repository which allows the user to run and build 32-bit applications on 64-bit installations of Arch Linux.
Directory structure
A 64-bit installation of Arch Linux with multilib enabled follows a directory structure similar to Debian. The 32-bit compatible libraries are located under /usr/lib32/
, and the native 64-bit libraries under /usr/lib/
.
Enabling
To use the multilib repository, uncomment the [multilib]
section in /etc/pacman.conf
(Please be sure to uncomment both lines):
[multilib] Include = /etc/pacman.d/mirrorlist
Then update the package list and upgrade with pacman -Syu
.
Disabling
To revert to a pure 64-bit system:
Execute the following command to remove all packages that were installed from multilib:
# pacman -R $(paclist multilib | cut -f1 -d' ')
If you have conflicts with gcc-libs reinstall the 64-bit versions and try the previous command again:
# pacman -S gcc-libs base-devel
Comment out the [multilib]
section in /etc/pacman.conf
:
#[multilib] #Include = /etc/pacman.d/mirrorlist
Then update the package list and upgrade with pacman -Syu
.
