If you try to launch AntConc on an Ubuntu-based 64-bit system, you get the following error message (tested with versions 3.2.4u, 3.3.5u, 3.4.0u and 3.4.1u):
./antconc3.2.4u: No such file or directory or ./AntConc: No such file or directory
The minimal dependencies I had to install in order for AntConc to start successfully on Ubuntu 64-bit were the following libraries (tested on Ubuntu 13.10 and Xubuntu 12.04 LTS):
sudo apt-get install libx11-6:i386 libxss1:i386 libxft2:i386
For TurnKey/Debian systems, see this post, for other Linux distributions see ongoing discussion on: https://groups.google.com/forum/#!forum/antconc
