[Autogen-users] debugging autogen w/ gdb

[Aaron T. <syn...@gm...>]

So I had a lot of fun yesterday debugging a strange problem with
autoopts- I'd pass options on the CLI, but they wouldn't be detected
as "set".

ie:

if (HAVE_OPT(FOO)) {
   # do something with FOO
}

would return false, even if --foo was passed.

Long story short, the problem ended up having nothing to do with my C
code or a bug in autoopts (it was a problem with automake), but it was
difficult to debug since I couldn't figure out how to get gdb to
provide any information on FOO.

things like:

p FOO
p HAVE_OPT(FOO)

all returned errors in gdb about unknown symbols or something like
that.  Can anyone share the trick?

Thanks,
Aaron
