RE: unresolved symbol

["Bob Piatek" <bobtek@fishcamp.com>]

Tom,

I'm using YellowDog Linux 2.1 for my development system.  I don't think
the modutils update is needed for 2.1 and, indeed, I can compile and
'insmod' modules on my host system just fine.

My problem is that I can't load modules on my embedded system.  Sorry I
wasn't clear about that in my posting.  I am using the kernel from:

ftp://ftp.denx.de/pub/LinuxPPC/usr/src/linux-2.4.4-2001-11-24.tar.bz2

and ramdisk:

ftp://ftp.denx.de/pub/LinuxPPC/usr/src/simple-ramdisk.image.gz

and have ported it to my custom hardware running with an MPC860.  BTW...
thanks to all who have contributed software for this effort especially
the PPCBoot project!

Correct me if I'm wrong, but it looks like the problem is caused by the
kernel not exporting the symbols that are needed by the module and not
in the actual module itself.  Is it that I built the kernel wrong
somehow, or maybe the libraries in 'simple-ramdisk' image aren't
sufficient, or is it something else?

Bob

It sounds like you're running YellowDog Linux 2.0, and thus need to
install the modutils update.
