64-Bit-Processors like Athlon 64 are able to execute 32- and 64-Bit-programs at the same time.

Currently I am working on an easy solution to solve this. It does not use a cross-compiler nor a chroot-environment. I just make use of the arch32-packages which are already there.

Note: All libs will be installed under /opt/lib32. Arch64 should not be affected by this. In the case of any problems use pacman -R lib32 to remove all libs.

Attention: Never try to install all libs with pacman -S lib32.

And do not install any arch32-package. lib32-* packages are made to run bin32-* packages


32bit packages can now be found in the [multilib]-repository. You will need to add this repository before downloading any 32bit lib.


You will always need to install lib32-glibc in order to execute 32-bit-programs. It might be necessary to fake the output of uname. Use the package linux32 for this.

Some c++-programs also need lib32-libstdc++5.


Programs using OpenGL need one of the following libs which fits to your graphicscard:

  • nVidia: lib32-nvidia-utils
  • ATI: lib32-catalyst-utils
  • DRI: (all opensource-drivers like those for Intel-chips) lib32-libgl-dri


Programs using QT should run at once after installing lib32-qt.

Alsa & OpenAL

For Alsa and OpenAL-Support you have to install lib32-alsa-lib and lib32-openal.

Tested Applications

  • Doom3, Enemy-Territory, Unreal Tournament
    • lib32-nvidia-utils, lib32-alsa-lib, [lib32-libstdc++5, lib32-openal]
  • Diablo II, Warcraft III
    • lib32-nvidia-utils, lib32-alsa-lib, [For Warcraft: lib32-openal]
  • Opera
    • lib32-qt
  • Google Earth
    • lib32-qt lib32-nvidia-utils lib32-gtk2 lib32-curl

Note : Google Earth seems to work here without lib32-qt

Environment Variables

Some useful Env Variables when running 32bit-applications without chroot:

For gtk2 input modules and such


For pango (lib32-pango includes these config files)


Iconv (conversion from 'XXXXXXX' is not supported or cannot convert from X to Y -errors)


Library paths without having them in /etc/ld.so.conf


GDK stuff (GdkPixbuf warnings errors criticals, lib32-gtk2 includes the file)
