Hi Folks,
Using FreeBSD 5.1 on a ia64 machine:
I have two kld driver modules (in different .ko files) one
(B.ko) of which depends, function call, on the other
(A.ko). When I kldload A.ko it loads as expected and
links correctly into the kernel. When I kldload B.ko
I get and error from kldload and the message
"kernel: link_elf: symbol A_status undefined"
I have EXPORT_SYMS=YES set in (both) driver Makefiles,
before the '.include <bsd.kmod.mk>' and the nm output
looks OK to me.
$ nm A.ko | grep A_status
00000a60 T A_status
$ nm B.ko | grep A_status
U A_status
Is this expected behaviour or is it a ia64'isim. Suggestions
and pointers to more information welcome.
Alan
PS The structure of the driver modules comes from
Solaris where this sort of thing works.
