Hi,
I look up gdb mailing-list thoroughly, 
but I can't find any link by which I can submit my email.
Sorry, I send directly the email to this mail address. 
I'm not a spammer.

I've pretty much hit a wall on multi-proc debugging, so I will have to ask for help now.
I want to debug multi-processes on linux/SMP with a single gdb.
The /proc filesystem of Gnu/Linux is much powerless than Digital-Unix's.
I can debug multi-proc on alpha/Digital-Unix with /procfs interface.Certainly, the debugger is dbx, not gdb.

Please! 
Can /procfs Linux support gdb?
Can gdb support the programming environments of  SMP?

GNU/Linux debugging uses primarily the "ptrace" interface, not /proc. 
Look at the GDB source; it supports x86 and Alpha GNU/Linux systems
already.
