Your binary is in... I forget what it's called -- oh, "mach-o" format. Our (fsf) gdb does not know how to read that file format. And it would be a huge job to port over the changes in apple gdb that tell it how to read mach-o files (besides the fact that they are "fat" files, or at least potentially might be). Sorry, I think you're out of luck. n179911 wrote: > I tried Joel Brobecker suggested in adding that option in gdb/main.c. > > But my program still won't come up in my debugger. > > [Session started at 2009-10-07 13:27:16 -0700.] > GNU gdb (GDB) 7.0 > Copyright (C) 2009 Free Software Foundation, Inc. > License GPLv3+: GNU GPL version 3 or later > This is free software: you are free to change and redistribute it. > There is NO WARRANTY, to the extent permitted by law.
