vmlinuz no symtab? while cross compiling...

[Jon Anderson]

I'm attempting to cross compile linux-2.6.8.1, along with a few external 
modules (madwifi, hostap-driver, aodv-uu). The kernel and (built-in) 
modules compile fine, but compiling every one of those external modules 
fails around MODPOST. For example, aodv-uu:

<snip userspace stuff>
make -C /home/janderson/var/autobuild/i386/root/usr/src/linux 
SUBDIRS=/home/janderson/var/tmp/autobuild/aodv-uu-0.8.1 modules

aodv_timeout.o routing_table.o seek_list.o k_route.o aodv_rreq.o 
aodv_rrep.o aodv_rerr.o packet_input.o packet_queue.o libipq.o icmp.o 
min_ipenc.o locality.o

 MODPOST
modpost: vmlinux no symtab?
/bin/sh: line 1:   798 Aborted                 scripts/mod/modpost -i

vmlinux /home/janderson/var/tmp/autobuild/aodv-uu-0.8.1/kaodv.o
make[2]: *** [__modpost] Error 134

madwifi and hostap-driver do the same thing: "vmlinux no symtab?".

I've messed around with cleaning out the scripts/mod directory, then 
running a make prepare (which seems to rebuild modpost), but that makes 
no difference.

For the moment, I can work around this (because I'm "cross compiling" 
for i486 on an i686 system) by just running make again in the kernel 
directory, but I would assume that wouldn't work when I have to do it 
for ppc. :-)

I guess I'm just looking for any information that might help me get rid 
of this error. Any pointers would be most welcome.

(Hopefully this is the right place to be posting such questions - if 
it's not, then I appologize.)

Cheers,

jon
