Hi,

can anyone please tell me exactly what position independent code means, or 
tell me I can find a good source of information? man gcc just states that if 
the -fpic is used the gcc generates position independent code, suitable for 
use int shared libs.

Thnx
// POA

Code is *position dependent* if the machine instructions contain
absolute addresses of variables and functions; the exact contents of
the machine code *depends* on the *position* of those variables and
functions.

Code is *position independent* if it is not position dependent.

Regards,
Martin
