System: FreeBSD dunstan.freebsd.czest.pl 5.4-STABLE FreeBSD 5.4-STABLE #5: Sun May 8 11:57:11 CEST 2005 dunstan@dunstan.freebsd.czest.pl:/usr/obj/usr/src/sys/HOME8 i386
>Description:
SVRv4 code depends on System V IPC primitives, which might be loaded as
KLDs. If they're not loaded before svr4.ko, its loading procedure will fail.
>How-To-Repeat:
SystemV options needs to be disabled in your kernel configuration:
[..]
#options SYSVSHM # SYSV-style shared memory
#options SYSVMSG # SYSV-style message queues
#options SYSVSEM # SYSV-style semaphores
# kldstat | grep sysv
# cd /usr/src/sys/modules/svr4
# make load
[..]
objcopy --strip-debug svr4.ko
/sbin/kldload -v /usr/src/sys/modules/svr4/svr4.ko
kldload: can't load /usr/src/sys/modules/svr4/svr4.ko: No such file or directory
*** Error code 1
Stop in /usr/src/sys/modules/svr4.
[..]
# dmesg | tail -1
link_elf: symbol msginfo undefined
>Fix:
Patch [diff.0.svr4_sysvec.c] adds MODULE_DEPEND macros.
