2.4.19-pre7 MIPS compile errors.

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.

gcc -I /usr/src/linux-2.4.19-pre7/include/asm/gcc -D__KERNEL__ -I/usr/src/linux-2.4.19-pre7/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -G 0 -mno-abicalls -fno-pic -mcpu=r5000 -mips2

make[1]: Leaving directory `/usr/src/linux-2.4.19-pre7/arch/mips/arc'
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__ -I/usr/src/linux-2.4.19-pre7/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -G 0 -mno-abicalls -fno-pic -mcpu=r5000 -mips2

make[1]: *** [signal.o] Error 1
make[1]: Leaving directory `/usr/src/linux-2.4.19-pre7/arch/mips/kernel'

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 ?

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:

make: *** [vmlinux] Error 1

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.
