Re: debug universal binary on 10.3?

Douh! 10.3's sed doesn't take the -l option. I guess we'll have to switch to perl. Try this all on one line in /usr/bin/gdb

exec perl -e 'while($len = sysread(STDIN, $buf, 1024)){$buf =~ s /-break-insert -l -1/-break-insert/g; syswrite(STDOUT, $buf, $len);}' | "$gdb" "$@"

I very much appreciate the heads up!

However, in my host machine, I see the following error:

sed: illegal option -- l

usage: sed script [-Ean] [-i extension] [file ...]

       sed [-an] [-i extension] [-e script] ... [-f script_file] ... [file ...]

I have copied the line below exactly like it was to my /usr/bin/gdb. Any clue?

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.

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?
