Hi,

i'm trying to use gdb on my iMac
--------------
appleton:MM110605 applemcg$ ls -l /usr/bin/*cc

i've used it successfully ( a prior version ) in the past on a ~ 32K
size C program and saw today for the first time the error message
reported in the "Building GDB on Darwin "

i followed the steps in "Creating a certificate", ran the codesign
command, and was treated with the same message:

Reading symbols from /Volumes/MM110605/src/eec/cummings...

done.
(gdb) run
Starting program: /Volumes/MM110605/src/eec/cummings
Unable to find Mach task port for process-id 95355: (os/kern) failure (0x5).

(gdb)

I included the "cant find section ... " messages as I don't recall
seeing them in times past, and to offer any kind of clue.

I did have to go to the trouble of resetting my login keys in the
OS X, as i really have little idea of what's happening. i do get the
RSA, public key algorithm, but frankly what a certificate represents and
who is giving whom what and why escapes my ken.

in the btw department; i tried this repeatedly. in the first
instance, i created a 2K Certificates.p12 file (before resetting the
password, but i was successfully able to import into the System keychain
as recommended. that failed as well. then repeating the experiment,
but this time with (continue)^ nth, i received "unknown error" when the
certificate was being created. in this pass i offered no identity to
the certificate assistant. repeating a 4th or fifth time, but
supplying identity, i was able to export a *.pem file, which is just the
ascii email attachment. needless to say it was not effective.

is there a cookbook for this procedure? do i need to rebuild gcc?

Thanks,
