Re: How to configure gdb to support '--arch=i386' on Mac OS X

Thank you. You are right.

The gdb comes with apple has '-arch'  option, but gdb 7.0 does not.

 $ /usr/bin/gdb --help
  --translate        Debug applications running under translation.
  -arch i386|armv6|x86_64|ppc     Specify a gdb targetting a specific
architecture

So should I do what Joel Brobecker suggested in adding that option in
gdb/main.c?

Thank you.
