I do not have much experience with LKM's or with ld, but it definately seems
that ld is having problems loading any of my LKM's.


bsd# cd /usr/lkm
bsd# modload -v -d ./if_ipl.o 
ld -A /netbsd -e _if_ipl_lkmentry -o ./if_ipl -T 0 ./if_ipl.o

modload: can't prelink `./if_ipl.o' creating `./if_ipl'
bsd# 


I have tried this with other lkm's too, they all do the same thing... I would
also assume that this is ld's problem not modload's since I have tried to
run:

ld -A /netbsd -e _if_ipl_lkmentry -o ./if_ipl -T 0 ./if_ipl.o

on its own, and I get the same exact error... does this mean that I should be
linking to some sort of library? any help or thoughts would be appreciated.

One more thing ... where did this object file come from (if_ipl.o)? How would
one go about making their own? (Just curious, since I compiled the ipf source
and never saw this object mentioned ... I don't think?)...

thanks,
phil
