RE: error message : I'm sorry, Dave, I can't dothat.Symbolformat'elf32-xc16x' unknown.

Hi Daniel,

	   The change had worked fine. Now gdb is working without 
"--disable-nls" switch.

However One more question just for little more information
---

I changed find_sym_fns() in gdb/symfile.c as to print the
value for
which file formats gdb has the support as follows.

static struct sym_fns *
find_sym_fns (bfd *abfd)
{
  struct sym_fns *sf;
  enum bfd_flavour our_flavour = bfd_get_flavour (abfd);
  enum bfd_flavour test_flavour;

  if (our_flavour == bfd_target_srec_flavour
      || our_flavour == bfd_target_ihex_flavour
      || our_flavour == bfd_target_tekhex_flavour)
    return NULL;	/* No symbols.  */

  for (sf = symtab_fns; sf != NULL; sf = sf->next)
  {
	  test_flavour = sf->sym_flavour; /* added line*/
	  printf_unfiltered (_("sys_flavour %d.. our flavour 
%d...n"),
test_flavour,our_flavour);     /* added line*/
      if (our_flavour == sf->sym_flavour)
      return sf;
  }
  error (_("I'm sorry, Dave, I can't do that.  Symbol
format `%s'
unknown."),
	 bfd_get_target (abfd));
}


This time I got following output :

This GDB was configured as "--host=i686-pc-cygwin
--target=xc16x-elf"...
sys_flavour 3.. our flavour  5...
sys_flavour 2.. our flavour  5...
sys_flavour 1.. our flavour  5...
sys_flavour 5.. our flavour  5...
sys_flavour 3.. our flavour  5...
sys_flavour 2.. our flavour  5...
sys_flavour 1.. our flavour  5...
sys_flavour 5.. our flavour  5...


my question is why the for loop has executed 2 times ? 
I mean to say once it has found 
"(our flavour== sf->sym_flavour)" and returning
"sf" for 1st time again
the loop is executed one more time to return the same.

Aha!

This means the configure check is buggy.  What happens if
you replace
this line:
  LIBS="$LIBS -lbfd -liberty"
with this:
  LIBS="$LIBS -lbfd -liberty $LIBINTL"

Use GDB to answer this question, of course.  Set a
breakpoint on
find_syms_fn and backtrace every time it's hit.
