Re: debug universal binary on 10.3?

Xcode 2.3 is passing a new argument to the gdb machine interface for setting breakpoints that 10.3's gdb doesn't understand. We can change the data stream to gdb on your 10.3 machine by changing /usr/bin/gdb on the 10.3 machine. I haven't tested this on a 10.3 install.

1. On your 10.3 machine backup /usr/bin/gdb

sudo cp /usr/bin/gdb /usr/bin/gdb.orig

2. On your 10.3 machine edit /usr/bin/gdb with your favorite command line editor

sudo pico /usr/bin/gdb

Then change the last line from something that looks sort of like (Sorry I don't have a 10.3 machine handy):

exec "$gdb" "$@"

to

exec /usr/bin/sed -l s/-break-insert\ -l\ -1/-break-insert/  | "$gdb" "$@"     

I'll filed a Radar on this.

Cheers,

I temporarily commented out the code that was causing the dyld errors. Apparently this was caused because I have references to Address Book and bindings constants available only on 10.4. So now I can get my app to launch on the remote machine and load into the debugger. But every time I try to set a breakpoint I get this:

mi_cmd_break_insert: Unknown option ``l''

Unable to set breakpoint  . Make sure to build the file   with debugging symbols.

any ideas what might be causing this?
