OK, I'm an idiot. The first time I used this solution, I must have typed something wrong a couple times, because now it's working. It still gives the "Error from Debugger" message, but it hits the breakpoints.

Thanks so much for the help.

I believe here, the solution Chris F. has posted to the list is appropriate:

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

Search the list archives for more info. I am using this solution very successfully on my 10.3 remote debuggin

Hello,

I'm new to remote debugging, for starters. I've set up my two mac machines for remote debugging and everything seems to work fine except for breakpoints. Every time I try to run the app I get the following message:

"Error from Debugger: No symbol table is loaded. Use the "file" command."

I think I know what the problem is. My local machine is running XCode 2.3, so it's using gcc 4 and gdb 6. My remote machine (using Mac OS 10.3.9) is using the XCode 1.5 tooles (the best I can get for it), thus it has gcc 3.3 and gdb 5.x. There's a conflict here; I assume breakpoints aren't working because of the gdb conflict.

I've tried installing different XCode toolsets on each machine, but the OS doesn't allow it. Is what I'm trying to do even possible?

Any help is greatly appreciated.

Thanks,

Ryan

ps - I forgot to mention, even though breakpoints don't work, the app still runs on the remote machine.
