hi!
I'm totally new to MIPS and the bigger trouble that I'm also
new to cross compiling.
I will get a little MIPS board with PCMCIA, USB, serial,
Ethernet, 4Mb flash memory. I have to build a linux for it
from scratch but I have never done cross compiling before.
I use debian (Woody) and I installed the toolchain package,
configured for mipsel-linux, I built the binutils and gcc,
(binutils 2.12, gcc 3.2.3)
I did:
tpkg-make mipsel-linux
cd binutils
debuild
debi
tpkg-install-libc mipsel-linux
cd ../gcc-3.2.3
debuild
debi
I can compile a simple c code, but I can't compile the kernel.
I tried to compile 2.4.19 and I ran into trouble at the beginning:
the 'as' said that -mcpu option is not recognized. OK, I removed
this option. Then everything seemed to be fine but when the
compilation arrived to the arch/mips directiory than I got the
following error messages:

The board chose was only a test bacause I don't know anything about
the board I'm going to use. There is a nice Japanese page about it,
but I can't read it.

Can anyone help? I have to bulid a complete little system in 4Mb
within a month.
I also tried to build the cross compile environment from the sources
directly not using toolchain but I got much less success. it didn't
compile at all (gcc).
Thanks a lot,
Gabor
