1. Help with linux
I've downloaded eu_engin.zip by Bernie Ryan.
When i try to run the demo program as user i get this error:
svgalib: Cannot get I/O permissions.
I'm using knoppix 3.3 debian install.
The demo run as fine as root, if someone can give a clue to which file i
should set permisson.
Tj.

From the svgalib FAQ:
8. Why does a programs terminate immediatelly with "svgalib: Cannot get I/O
permissions."?
svgalib programs need to be run as root. This means that either the user that
runs them is root, or, if running by normal users is desirable, the program needs
to be 'suid root', which means: the program must be owned by root (chown 0
program) and the suid bit needs to be set (chmod u+s program).

Thomas:
Alex is correct about the svgalib needing to be run as root.
You can learn more about the svgalib at this URL.

Thanks to you and Bernie for take your time to help with this issue.
