UNIX (such as Linux) users

In this tutorial we assume that you have added $ADFBIN to your PATH. We advise you to do this if you have not already done so. If you do not wish to add $ADFBIN to your PATH, you must start the utilities using

$ADFBIN/adfinput &

instead of just

adfinput &

On all UNIX platforms, including Mac OS X, the ADF-GUI programs are XWindow programs. Your environment should have been set up correctly to run such programs. In particular, you need to make sure that your DISPLAY environment variable has been set properly.

You can test this easily by starting a simple X program from your shell:

xcalc &

Assuming the xcalc program is in your $PATH, a small window should appear with the image of a calculator. If not, please consult your local system administrator for additional help. Typical problems have to do with your DISPLAY variable, and with security issues when trying to connect to the X server.
