 * Arch (tested continuously with our own dockerfile and then travis)
+As for the other distros, you'll need gcc capable of producing 32 bit binaries. The package is called `gcc-multilib`, but it conflicts with `gcc` which you probably have installed already. One way to solve this (based on our Dockerfiles) is:
+```
+pacman -R --noconfirm gcc
+pacman -S gcc-libs-multilib
+pacman -S --noconfirm gcc-multilib
+```
+Then install packages:
 ```
 yaourt -S --noconfirm lib32-jansson lib32-curl lib32-sdl2 lib32-sdl2_ttf \
     lib32-speex
