Question

I’am now dealing with a new project, threre exist several struct for varaible transfering in parallel programming, can anybody give some hint on how to use gdb to watch struct chage process step by step, thanks first:)

Answer 1

You can try GDB watch command. However, as stated by this link :

Warning: In multi-thread programs,
watchpoints have only limited
usefulness. With the current
watchpoint implementation, GDB can
only watch the value of an expression
in a single thread.

If that’s a deal breaker for you, I guess you will have to instrument your code to manually track changes.
