Re: Build failure: Error: attempt to move .org backwards

[Seth Goldberg]

Hi,

  Yes, I'm seeing that also.  I guess version 4.5.2 of the compiler just isn't 
as efficient as the most-recent GCC.  I edited include/grub/offsets.h:

And changed:
#define GRUB_KERNEL_I386_PC_NO_REED_SOLOMON_PART 0x7e0

To:
#define GRUB_KERNEL_I386_PC_NO_REED_SOLOMON_PART 0x7f0

 And that was enough.  phcoder posted to this list not-too-long-ago with that 
suggestion for another person as well.  He said you can increase it as long as 
you don't do it too much and as long as the value is divisible by 8.
