Hello all,

I was compiling a milo-0.27 lately on i586 machine for mips32 platform.
I am using binutils 2.8.1 egcs1.0.3a, and glibc 2.0.6. I am using some custom
MIPS board
with QED RM5261 processor. I use patched 2.2.14 kernel which is known to compile
and run on my hardware.

./configure went smoothly, but at a build time I started to get problems. First,
I got missing <asm/pica.h>. After a short search I have found one in annals of
the Internet.

This didn't really help me, because finally I got an assembler errors for
libstand/cachectl.o:

[michaels@kobie libstand]$ make
mips-linux-gcc -Wall -O2 -mips2 -Wa,-mips3 -mcpu=r4400 -D__KERNEL__
-DLOADADDR=0x80600000 -DKERNELBASE=0x80000000 -DVERSION=0.27 -DDEBUG=1
-DBOOTMETHOD_ARC -nostdinc
-I/usr/local/lib/gcc-lib/mips-linux/egcs-2.90.29/include
-I/home/michaels/atlas/rg.mips/linux/include -I../libstand/include
-I../libarc/include -c cachectl.S -o cachectl.o
cachectl.S: Assembler messages:
cachectl.S:58: Error: absolute expression required `li'
cachectl.S:59: Warning: Instruction cache requires absolute expression

cachectl.S:66: Warning: Instruction cache requires absolute expression
<and many more like these>

Line 58 is
 li t1,CACHELINES-1
Line 59 is
  cache Index_Writeback_Inv_D,32(t0)

and obviously CACHELINES is not defined anywhere, not even within the kernel
source tree. At least not my patched 2.2.14. Also, I am confused what causes
cache to go crazy on Index_Writeback_Inv_D ...

So, if anyone has ideas, plase forward them on.
Also, I wonder if there is a public CVS repository for milo or any other
"authoritative" storage.

Thanks in advance,
Michael.
