I just now learning how to use GDB.
I wanted to look at an int that was part of a struct in global space.
The global is called header and the int is called start.
I tried many variations of
print header.start
but all it says in return is
Attempt to extract a component of a value that is not a structure.
What is the proper way to display a global value?
What does
ptype header
show?
You can always cast it
print ((struct header *)&header)->start
and for convenience you can set a user defined variable
set $header = (struct header *)&header

Did you specify -g option when you compile the files?
