2.4.19-pre7 MIPS compile errors.

2.4.19-pre7 MIPS compile errors.

[Malcolm Mallardi]

The MIPS box (an SGI Indy) has been having problems compiling kernels
since I first put Linux on it I've never had a kernel complete the
basic image compile (make vmlinux)  between 2.4.16-2.4.18 there were
problems compiling one of the keyboard drivers, 2.4.19-pre5 had the two
problems I'm about to describe, as does 2.4.19-pre7.  2.4.19-pre6
wouldn't even attempt to compile.

It's an R5000/150Mhz, 128M RAM, Newport graphics, Debian Woody, gcc
2.95.4, binutils 2.12.90.0.1 20020307.

First problem seems to be in the ARCs Console support subsystem of the
kernel.

make: *** [_dir_arch/mips/arc] Error 2

The second error, I run into when I disable ARC console support, and
attempt to compile again. Not as sure about what causes this one,
though.

gcc -I /usr/src/linux-2.4.19-pre7/include/asm/gcc -D__KERNEL__

make[1]: Leaving directory

Anyway... I'm hoping that this information is useful, if y'all need any
more, please just ask.

Hi Malcolm,

for the second problem did you try to add #include <linux/personality.h> 
line in signal.c ?

[PATCH] arch/mips/kernel/signal.c, still more errors, though.

That did indeed fix that build error, so here is the patch for said
fix.

Though I am left with yet another build error during the final linking:

The first part of that error was likely a config snafu (I defined both
standard serial and SGI serial) The second looks like a problem with
Irix binary compatibility, I'm disabling that as well.

Disabling those two things has left me with a compiled kernel.

The stock kernel doesn't build for MIPS nor has all the latest fixes.
Get the latest 2.4 kernel from the cvs archive on oss.sgi.com, branch
linux_2_4, see also the section about anon cvs in
http://oss.sgi.com/mips/mips-howto.html.
