Debian/Ubuntu

The following 32-bit libraries are available as packages that can be installed using apt-get on the command line or graphically using Synaptic:

• ia32-libs
• ia32-libs-gtk (not required for Hardy 8.04 and later)

To install these packages from the command line:

sudo apt-get install ia32-libs ia32-libs-gtk (NOTE for Ubuntu 12.04+, see below)

Next you will need to use Getlibs to install a 32-bit version of xulrunner:

• Download getlibs-all.deb

• Install getlibs-all.deb by running:

  sudo dpkg -i getlibs-all.deb
  

• Install the 32-bit xulrunner by running:

  sudo getlibs -p xulrunner-1.9.2
  

• Setup the IDE to use your recently installed 32-bit xulrunner:

  export MOZILLA_FIVE_HOME=/usr/lib32/xulrunner-1.9.2.X
  

  Substitute X for the version you see installed on your system. You will need to set this environment variable every time you start the IDE.

Ubuntu 12.04 and later

Since 12.04 Ubuntu introduced Multi Arch (https://wiki.ubuntu.com/MultiarchSpec) and removed ia32-libs ia32-libs-gtk packages from the repository. To install 32-bit libs you need the run the following command line:

sudo apt-get update
sudo apt-get install libgtk2.0-0:i386 libxtst6:i386 gtk2-engines-murrine:i386 \
lib32stdc++6 libxt6:i386 libdbus-glib-1-2:i386 libasound2:i386

Note, you may need to run the following command first if the message Unable to locate package <package name> appears:

sudo dpkg --add-architecture i386
