64-Bit-Processors like Athlon 64 are able to execute 32- and 64-bit programs at the same time.
Contents
Packages
32bit packages can now be found in the [multilib]-repository. You will need to add this repository before downloading any 32bit lib.
Installation
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 legacy C++ programs also need lib32-libstdc++5.
OpenGL-Applications
Programs using OpenGL need one of the following libraries:
- Open source drivers: lib32-{ati,intel,mach64,mga,nouveau,r128,savage,sis,tdfx,unichrome}-dri
- Closed source drivers: lib32-{catalyst,nvidia}-utils
- Software rendering: lib32-libgl
QT-Applications
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.
Environment Variables
Some useful Env Variables when running 32bit-applications without chroot:
For gtk2 input modules and such
GTK_PATH=/opt/lib32/usr/lib/gtk-2.0/
For pango (lib32-pango includes these config files)
PANGO_RC_FILE="/opt/lib32/config/pango/pangorc"
Iconv (conversion from 'XXXXXXX' is not supported or cannot convert from X to Y -errors)
GCONV_PATH=/opt/lib32/usr/lib/gconv
Library paths without having them in /etc/ld.so.conf
LD_LIBRARY_PATH="/opt/lib32/usr/lib/:/opt/lib32/lib/:$LD_LIBRARY_PATH"
GDK stuff (GdkPixbuf warnings errors criticals, lib32-gtk2 includes the file)
GDK_PIXBUF_MODULE_FILE="/opt/lib32/config/gdk/gdk-pixbuf.loaders"
