Linux distributions differ, particularly so in the selection of tools and libraries pre-installed in standard configurations. This page provides Ubuntu-specific information related to installing and operating the LOGON infrastructure (for general installation guidelines, please see the LogonInstallation page). The information on this page is user-provided documentation. As you extend or revise the page, please take care to spell out (a) the specific problem to be addressed, including observable symptoms; (b) the exact platform (32- or 64-bit) and version of the distribution affected; and (c) the exact procedure to be applied for fixing the problem.

32-Bit Compatibility Libraries

As recommended in LogonInstallation, you'll want 32-bit libraries on 64-bit systems.

In recent Ubuntu's (such as 14.04) you should do:

sudo dpkg --add-architecture i386
sudo apt update
sudo apt install libjpeg62 libx11-6:i386 libxext6:i386 libfontconfig1:i386

For older versions, try:

  sudo apt-get install ia32-libs

As well as the libraries, LOGON components such as [incr tsdb()] may complain about missing libraries. Installing the following packages solved the problem at least on one jaunty system (please add more if you find problems from running other components):

  sudo apt-get install libxpm4 libxt6 libxmu6 libxft2 libjpeg62 libpng12-0

On Precise Pangolin (12.04) you may only need libjpeg62.
