As you probably know, we’re working hard on having the Xojo framework and IDE support 64bit. While this work is still in progress, there are more and more distributions mainly available as 64bit. If you can’t work and/or deploy on a 32bit distribution, you need to get the IDE or your Xojo apps working properly on a 64bit distribution.
Here is some code that helps make it possible on Ubuntu 14.04 (it should work on any Debian too, but I didn’t test that):
Type these commands in your preferred terminal app:
sudo apt-get install libc6:i386
echo "deb http://old-releases.ubuntu.com/ubuntu/ raring main restricted universe multiverse" > ia32-libs-raring.list
apt-get install ia32-libs
sudo apt-get install gcc-multilib
Xojo and your Xojo apps should now work normally. Though you may notice that using a HTMLViewer on a 64bit distribution will throw an exception.
