Re: binutils-2.9 objcopy fails (fwd)

I went ahead and asked the obvious questions on the m68k-rtems objcopy
failure.  I hope it helps.

Thanks.  Perhaps you could forward this, too?
It's been so long since I had to make a 32-bit bootstrap prom that I  
don't remember which version I used to use. :-(

I just built with whatever `bit' does.

I'm pretty sure that I'm not trying to build anything with shared  
libraries.

Just for the heck of it, I tried running this under gdb.  I found  
that the text segment of prom.exe seems to be copied with no problem,  
but the data segment fails:
Breakpoint 3, copy_section (ibfd=0xe61a0, isection=0xe6994,  
obfdarg=0xe9220) at  
../../src/binutils/../../src/binutils/objcopy.c:1287
1287              if (!bfd_set_section_size (obfd, osection, size))
(gdb) step
1288                nonfatal (bfd_get_filename (obfd));
(gdb) print size
$5 = 1900


The fact that this fails the second time through is not too  
surprising, given the code at the beginning of  
bfd_set_section_size........

boolean
bfd_set_section_size (abfd, ptr, val)
     bfd *abfd;
     sec_ptr ptr;
     bfd_size_type val;
{
  /* Once you've started writing to any section you cannot create or  
change
     the size of any others. */

  if (abfd->output_has_begun)
    {
      bfd_set_error (bfd_error_invalid_operation);
      return false;
    }
