gdb-7.0 on osx

[Tobias Hahn <tobias.hahn@ableton.com>]

Hi all,

I cannot get gdb-7.0 to debug my executables under 10.6. I have built  
it using

$ ../gdb-7.0/configure --build=x86_64-apple-darwin10 CFLAGS="-g -O2 - 
Wno-format"
$ make
$ codesign -s gdb-sign gdb/gdb

(The certificate gdb-sign is in the System keychain and is valid for  
codesigning.)

When I try to debug an exe, it first gives me an error about no  
debugging symbols found (even though I have compiled them in with -g):

(gdb) file /tmp/t/t
Reading symbols from /private/tmp/t/t...(no debugging symbols  
found)...done.

Trying to run the program fails:
(gdb) run
Starting program: /private/tmp/t/t
Unable to find Mach task port for process-id 10609: (os/kern) failure  
(0x5).
  (please check gdb is codesigned - see taskgated(8))

I suspect I might need to sign gdb differently (since using sudo gdb  
works). Can anyone help me here?

Thanks in advance,
Best,
  Tobias
