Florian,
Thanks for your respond. "add this as a patch to the kernel src.rpm and
then rebuild the ...."--> Do you mean rebuilding the kernel with 2.4.9-31
source tree and compile my file again? Anyway I did the following ways and
got the same error:
1 - applied "kernel-2.4.9-31.s390.rpm", "modutils-2.4.13-0.7.1.s390.rpm",
"kernel-source-2.4.9-31.s390.rpm" and "kernel-headers-2.4.9-31.s390.rpm".
IPLed the system with shipped 2.4.9-31 kernel and compiled the
testvm.c from /usr/src/linux2.4.9-31 tree.
2 - Rebuilt the kernel with the 2.4.9.-31 updates. IPLed the system with
the rebuilt kernel and compiled the testvm.c from /usr/src/linux2.4.9-31
tree.
However when I changed the Makefile in the directory
"/usr/src/linux2.4/drivers/s390/net" to include the testvm.o and did the
"make modules", the testvm.c was complied with only warning (no undeclared
error). I did this on both 2.4.9-17 and 2.4.9-31 kernel and trees. And I
was also able to insmod the testvm.o with no error.
(I do not have to do this on SuSE SLES-7.0).
The changed (in bold) /usr/src/linux2.4/drivers/s390/net/Makefile:
----------------------------------------------
#
# S/390 network devices
#
O_TARGET := s390-net.o
list-multi := ctc.o
export-objs := iucv.o fsm-s390.o
ctc-objs := ctcmain.o ctctty.o testvm.o
obj-y += iucv.o fsm-s390.o
obj-$(CONFIG_CTC) += ctc.o
obj-$(CONFIG_IUCV) += netiucv.o
include $(TOPDIR)/Rules.make
ctc.o: $(ctc-objs)
$(LD) -r -o $@ $(ctc-objs)
My scaled down (only have #includes and #defines) "testvm.c":

We are currently working on porting an application on to 2.4 kernel.
We did that for SuSE-SLES 7.0 (2.4.7) and now we like to work on the Redhat
distribution.
Any help will be greatly appreciated. Thanks,
Chong

I'd advise to add this as a patch to the kernel src.rpm and then rebuild
the complete kernel to build kernel modules. Or unpack the kernel, select
your correct config "cp linux/configs/* linux/.config; make oldconfig; ..."
and build your modul in that tree.
Or just send your testvm.c file here... :-)
