gdb simulator exit status

gdb simulator exit status

[M R Swami Reddy]

Hi,
I have C file as:
==
main () {
   return 1;
}
===

When I compile and run it, the status value is '1'
 > a.out
 > echo $status
 > 1

When I execute the same "a.out" on gdb simulator, the status shows as "0" (ie 
gdb's exit status) and gdb shows "Program exited with code 01".

Can you please suggest the way (if any) to get the gdb simulator's exit status 
with "echo $status" command"?

Thank in advance.

Thanks,
Swami

Well, it works for me (target sh-elf), but maybe I'm using a more recent 
GDB or something.

Anyway, obviously it isn't working for you, so try this:

gdb --batch-silent \
	--return-child-result \
	-ex "target sim" \
	-ex load \
	-ex run \
	a.out

Hope that helps

Andrew

It sounds like a bug in your particular simulator.

Thank you very much. The "--return-child-result" option works for me too.

Thanks,
