[Lustre-discuss] Luster 1.6.3 & cross compilation

Hi -

Time to give Lustre another shot since it now supports a kernel  
version I can get built on my mac G5 linux cluster :-).

Since I am still running Debian Sarge on the nodes in 32-bit mode,  
and the kernel needs to be build in 64-bit mode, I need to build in a  
cross compilation environment. This gets close to seeming to work:

I can patch and build the kernel no problem (2.6.18.8).

I can configure & build lustre --without-modules.

When I try to build modules I get a cross compilation test for module  
compile failing that requires this hack patch to add the needed  
CROSS_COMPILE option to the kernel make:

    { (eval echo "$as_me:$LINENO: \"$ac_try\"") >&5
    (eval $ac_try) 2>&5
    ac_status=$?


After that is in place, I can run through the compile until it tries  
to configure ldiskfs. configure error output below.

Thanks for any advice.
