Building on Darwin

Hi,

    i'm trying to use gdb on my iMac

   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:

done.

    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,
