Help/Support PuTTY problem unrecognized arm osabi

[Goggwell 17.8k iPod Touch 1.0.0]

warning: Unrecognized osabi 0 in arm_set_osabi_from_host_info

 

This line is preventing me from doing anything related to GDB. I can't attach the binary or watch an offset. Please help someone!

it's not putty, seems that you are trying gdb on an device that it cpu arch wont support by gdb (should be arm64). Use lldb instead.

U can see this in Apple's code

switch (info.osabi)
    {
      case GDB_OSABI_DARWIN:
    info.bfd_arch_info = bfd_lookup_arch (bfd_arch_arm, 0);
        break;
      case GDB_OSABI_DARWINV6:
        info.bfd_arch_info = bfd_lookup_arch (bfd_arch_arm, bfd_mach_arm_6);
        break;
      case GDB_OSABI_DARWINV7:
        info.bfd_arch_info = bfd_lookup_arch (bfd_arch_arm, bfd_mach_arm_7);
        break;
      case GDB_OSABI_DARWINV7F:
        info.bfd_arch_info = bfd_lookup_arch (bfd_arch_arm, bfd_mach_arm_7f);
        break;
      case GDB_OSABI_DARWINV7K:
        info.bfd_arch_info = bfd_lookup_arch (bfd_arch_arm, bfd_mach_arm_7k);
        break;
      default:
        warning ("Unrecognized osabi %d in arm_set_osabi_from_host_info", (int) info.osabi);
    }

Now I have to get VMWare...

This happens to me all the time on my iPad Air. It doesn't really do anything except watch points won't really work properly using break points work perfectly I always get this message on my iPad Air.

It's a problem that happens on PuTTY so it's a "PuTTY Problem".

I still can't do gdb. PuTTY is refusing to let me do anything. I get errors when attaching a binary, or even setting a watchpoint or breakpoint.

Are the errors as you see above?

What's your idevice ? If it's running arm64, u can only debug app with lldb and debugserver (can find it in xcode) since apple only support gdb up to armv7
