Description robfitz 1999-01-09 14:05:43 EST 
Hello

The url above is a kernel for The JOS Project (www.jos.org).
 There is a problem in which the above kernel it can't be
compiled using Redhat 5.2, it work's with Redhat 5.0 and
Caldera 1.1 (after upgrading binutils).

This is the output of 'make all' on Redhat 5.2:
$ make all
gcc -Wall -O2 -I ./include -c boot.s
gcc -Wall -O2 -I ./include -c start.s
start.s: Assembler messages:
start.s:17: Error: Value of -65472 too large for field of 2
bytes at 9
start.s:18: Error: Value of -65432 too large for field of 2
bytes at 14
make: *** [all] Error 1

The two lines giving the error are:
	lgdt	(gdtr - kaddress)
	lidt	(idtr - kaddress)

The output for 'as -al start.s' for Redhat 5.2 and Redhat
5.0 is below, as you can see the wrong opcodes are being
produced.

Redhat 5.2
  17 ???? 0F011640              lgdt    (gdtr - kaddress)
  17      00
  18 ???? 0F011E68              lidt    (idtr - kaddress)
  18      00

Redhat 5.0
  17 0006 670F0115              lgdt    (gdtr - kaddress)
  17      4800FFFF
  18 000e 670F011D              lidt    (idtr - kaddress)
  18      7000FFFF

After getting down binutils-2.9.1.tar.gz from
metalab.unc.edu/pub/gnu and installing, I was able to
compile the above kernel.
