how to build a kernel extension

[Steve Dyer]

I have the manual named "Kernel Extensions and Device Support Programming
Concepts", but while it goes into some issues in excruciating detail,
I can't really find ANYWHERE where it addresses the simple step-by-step
set of instructions you must follow to create a loadable kernel extension
file once you compile your extension foo.c and get a foo.o file.

I get the impression that you need to specify to "ld" an export file and
import file for symbols, but more than that, who knows?  I did what
I thought was reasonable, and got an image with no undefined symbols,
but the output from the linker causes the sysconfig SYS_KLOAD system
call to return "Exec format error".

Has this procedure been summarized somewhere in the documentation
and I just am not finding it?
