I was able to build it from source myself:
Building Version 9.4 of Icon from Source
The short of it is...
$ mkdir src
$ cd src
$ wget http://www.cs.arizona.edu/icon/ftp/packages/unix/icon.v943src.tgz
$ tar -xzf icon.v943src.tgz
$ cd icon.v943src
$ make Configure name=linux
$ make Test
$ make Install dest=~/icon
$ make Clean
And then your path to the icon binaries will be:
Though if you already have a /home/username/bin directory in your PATH you can use a symbolic link:
ln -s /home/username/icon/bin/icont /home/username/bin/icont
ln -s /home/username/icon/bin/iconx /home/username/bin/iconx
Well I just compiled Icon on a shared server...
If you notice it is usually stuff that is popular that gets written up. So we got instructions on compiling PHP and a few other things but this is first I've heard of Icon myself.
