[Linux-ia64] Linker error : linking constant-gp files with non-constant gp fil

[Sistla, Krishnakanth V]

Hi all,

	I am trying to write a miscellanious driver and compile it into the
linux
	kernel. When i try to link two object files created by the below
mentioned 
	commands (during a build) i get the following error. could some help
me 
      please ?

Thanx in advance
KK

All objects that are linked into the kernel must be compiled with
-mconstant-gp.  All objects that are linked into modules must not be
compiled with -mconstant-gp.  Set your compile flags accordingly.

That's not sufficient.  You need to use pretty much *all* the flags
that normal kernel compiles use, in particular the -mfixed* options
are important.
