FYI, that isn't an error, it is an informational message.  The
instruction at line 3755 isn't implemented.  This may sound serious but
it isn't.  Have a look at the actual instruction - will GCC generate it?

Subject: Why doesn't exist a 68k emulator in GDB?

Hello:

      68k is a simple and popular processor.
      Many embedded systems use 68k, but GDB
      doesn't exist a 68k emulator.
      GDB exist many others emulator , ex: ARM, ...
      Who can explain that if I have a emulator and
      a GDB, how to combine them to work together?
      It exists any document about this?
      Thanks very much.

					Ps. Chen
