Re: Trouble compiling 2.5.30 on old powermac

Hello all,

first of all, a big thanks to all hackers for the 2.4.x
releases that have been fine for me for a looong time :-)

But to be able to port the "pm3fb" driver to 2.5, I need
a 2.5.x kernel. None of those I tried compiled.
Michel Dänzer suggested posting my problems here, so here
it is.

The box is an old 7500 upgraded with a 192Mhz 604e, running
Debian (used to be "woody", now it's "sarge"). binutils come
from Debian "sid" as I need the newer binutils for 2.5.
Additional hardware include an old mac-flashed Matrox
Millenium, and a Formac Proformance III video card (the one
that need pm3fb).

Source tree is linuxppc-2.5 from source.mvista.com,
through rsync.

1) at least 3 non-essential drivers cannot compile:
  the mac serial port, the mac floppy drive, and the
  external SCSI bus (53C94, MESH compiles). I can
  provide the errors if they're needed.

Yup, I fixed MESH, Cuda, via-pmu, adb, but not macserial nor
swim3 nor 53c94 yet, those are on my todo list. As far as macserial
is concerned, I need to look into the new serial driver framework
made by Russel King and figure out enough of it to port the driver.

2) arch/ppc/kernel/process.c fails with:
#####

That's a new one. Paulus ? Incorrect merge ? Missing include ?

Ben.
