Segmentation fault usually means that the program
is trying to access memory which doesn't belong to
it, and the kernel smacks it over the head.

In windows terms, a segmentation fault="Illegal Operation Error"

so what can be the problem then with all that files ???

Maybe it has to do something with your hardware? Maybe the MMU (memory managing unit) is directing to wrong places... don't know though, just a thought

Why don't you try to download the source files instead, maybe they will work for you.

The stuff you installed may be compiled
against a different (incompatible) version
of GLIBC

Incorrect.
"Segmentation Fault" in Linux is equivalent to "Access Violation" in Windows, not "Illegal Operation" error.

I get this segmentation fault error:

Code:

rforth@sibelius:~$ /sata/sata_250_dsk02/games/bmtg3/bin/BMTG3

Yet if I go into the bin directory and run it from there it runs fine? any ideas?

I think the "Illegal Operation" error (or "(application) has encountered a problem and needs to close") is Windows' terminology for an unhandled exception in a program. I got stuff like that when I used to do Win32 programming.
