Installation (old versions)

The program itself:

If you want to try wsat without actually recording you can put wsat where you like. However, if you want to record as normal user then wsat needs super-user privilege, to access the parallel port.
The next steps you have to do as super-user (under root): Now check if wsat runs. If you get an error message like:
wsat: can't load library ''
you need to install the gtk libraries.

  • NOTE: It seems that the new gtk-libs don't allow to run programs with super-user privilege by non-root users. Which means that you need to be root to record with wsat. This issue has to be solved in a proper way...

    Install libs:

    Double-check if you have gtk-libs: If they are there you probably need to add /usr/local/lib to the file /etc/
    Otherwise install the gtk-libraries.


    To make sure that data transfer from the parallel port is reliable (especially for a long time) make sure that:

    That's it!

    Note on wsat installation.

    The way described here to install wsat (with the chmod +s command) is not really nice because normal users have now super-user privilege via wsat. This has to be changed some day (using a driver, it shouldn't be necessary to give wsat super-user privilege).
    For single-user systems the 'superuser-wsat' is not a real problem.

    Reported bugs:

    None (but of course, there are...)

    Test version.

    This is a test version of wsat.exe. It can be changed any time without notice and can show unexpected behaviour. For normal use download
    this version!
