Like John said, there needs to be a module dependency.  The dependency from
linux to sysvsem (for example) is used for two things.  1) to prevent
sysvsem being unloaded before linux, and 2) to add sysvsem to the symbol
search order for linux.  You cannot "see" symbols in other modules without
registering a dependency for this reason.

there is no sysvipc module but this is what I tried..

jules# cd /boot/kernel
jules# ls sy*
sym.ko  syscall_gate.ko sysvmsg.ko  sysvsem.ko  sysvshm.ko
jules# kldload sysvmsg
jules# kldload sysvsem
jules# kldload sysvshm
jules# kldload linux
link_elf: symbol semop undefined
kldload: can't load linux: Exec format error
jules#

kldload sysvipc.ko or compile the SYSV stuff into your kernel.
Perhaps the linux kld needs to have a module dependency on
the sysvipc modules?

cd /usr && mv include include.not && cd src && make includes && rm -fr ../include.not

This worked for me.

but vmware in combination with Linux (as a module) is still broken.
vmware cannot find a symbol in the other (linux) module..
in other words, cross module symbol resolution seems to be
broken.
(cvsup as of a couple of hours ago)

-current (theoretically) rebuilds the modules when you rebuild the kernel.

It does, in fact, work now, thanks.

Nope. Used to have, though.

COMPAT_LINUX worked, but not the module.

Re: linux broken

[George W. Dinolt]

Michael:

I suspect that you may have

options COMPAT_LINUX

defined in your kernel config file.

Re your problem with Linux not working. I had the same problem. It seems
to be related to the changes in the generation of the file
linux_assym.h. A new method for generating these kind of symbols was
introducted into the kernel build system today. The changes were not
promulgated to the generation of linux_assym.h.

The following change to /usr/src/modules/linux/Makefile will allow one
to at least build a workable linux module.

*** Makefile~   Sat May 27 10:04:09 2000
--- MakefileSat Jun  3 00:11:05 2000
***
*** 17,23 
  CLEANFILES= linux_assym.h linux_genassym.o

  linux_assym.h:linux_genassym.o
!   genassym ${.ALLSRC} > ${.TARGET}

  linux_locore.o:   linux_locore.s linux_assym.h
${CC} -c -x assembler-with-cpp -DLOCORE ${CFLAGS} \
--- 17,23 
  CLEANFILES= linux_assym.h linux_genassym.o

  linux_assym.h:linux_genassym.o
!   sh /usr/src/sys/kern/genassym.sh ${.ALLSRC} > ${.TARGET}

  linux_locore.o:   linux_locore.s linux_assym.h
${CC} -c -x assembler-with-cpp -DLOCORE ${CFLAGS} \

If you don't keep your srcs in /usr/src, you will have to modify the
fixes appropriately

I am sure that there is a much cleaner way of fixing this, but I will
leave it to the gurus to work that out. I think a similar fix to the
kernel Makefile would allow one to build a working kernel with
COMPAT_LINUX built in.

There may be other modules or pieces of the kernel which may be affected
by the new symbol generation facility. I have not been bitten by the
problem  yet nor have I looked for them, so I can't speak first hand of
the issues.

Hope this helps.

You didn't rebuild your modules at the same time.
