I have made some progress and again got stuck - see step 4 below!
1. Must run "make ARCH=um" as with kernel build. This solved the
sysdep/faultinfo.h missing errors and makes sense given that the kernel
itself had this flag set for all "make" script calls.
2. According to
http://www.it.kth.se/courses/2G1305/nistnet-under-ubuntu-20061012.html
To fix the following problems with compiling of knistnet:
/home/maguire/nistnet-3.0a/kernel/knistnet.c:916: error: too few
arguments to function ippt->func
/home/maguire/nistnet-3.0a/kernel/knistnet.c:961: error: too few
arguments to function ippt->func
/home/maguire/nistnet-3.0a/kernel/knistnet.c:972: error: too few
arguments to function ippt->func
/home/maguire/nistnet-3.0a/kernel/knistnet.c:1003: error: too few
arguments to function ippt->func
you simply need to add another argument to the call, so that it looks like:
return ippt->func(skb, dev, ippt, NULL);
and then (not hit this yet):
After doing the 'make' and 'make install', I cheated and manually added
a line to the file /lib/modules/2.6.15.7-ubuntu1/modules.dep
/lib/modules/2.6.15.7-ubuntu1/extra/nistnet.ko:
Thus the modprobe in the Load.Nistnet now finds the nistnet module.
3. I now have the KBUILD_BASENAME problem from some semaphore assembly
code in
kernelsource /include/asm/semaphore.h
';' or ')' required before KBUILD_BASENAME
The web site used in 2 above also had this issue but in a different
place so trying:
If you get error messages: saying
error: syntax error before KBUILD_BASENAME
Change nistnet/Config: EXTRA_CFLAGS += $(OURINCS) $(DEVDEFS) -fno-common
to
See: http://www.it.kth.se/courses/2G1305/nistnet-under-ubuntu-20061012.html
for further details of runtime issues with missing files etc.
EXTRA_CFLAGS += $(OURINCS) $(DEVDEFS) -fno-common
-DKBUILD_MODNAME=\"nistnet\" -DKBUILD_BASENAME=\"nistnet\"
See http://www.ubuntuforums.org/archive/index.php/t-192942.html for
details.
This appears to resolve the problems here.
4. Current problem:
In file included from /mnt/hostfs/nistnet-3.0a/kernel/fast_rtc.c:67:
include/linux/mc146818rtc.h:16:59: error: asm/mc146818rtc.h: No such

make[3]: *** [/mnt/hostfs/nistnet-3.0a/kernel/fast_rtc.o] Error 1
Have tried various suggestions on this as there are plenty of instances
of this file in the headers but they all seem to fail to find something,
normally the
asm/mc146818rtc.h which seems to be referenced from the arch specific
versions of the file.
I have these versions of the file:
root) ls ../linux-2.6.18.1/include/asm*/*/mc14681*.h
../linux-2.6.18.1/include/asm/arch/mc146818rtc.h
../linux-2.6.18.1/include/asm-mips/mach-atlas/mc146818rtc.h
../linux-2.6.18.1/include/asm-mips/mach-dec/mc146818rtc.h
../linux-2.6.18.1/include/asm-mips/mach-generic/mc146818rtc.h
../linux-2.6.18.1/include/asm-mips/mach-ip32/mc146818rtc.h
../linux-2.6.18.1/include/asm-mips/mach-jazz/mc146818rtc.h
../linux-2.6.18.1/include/asm-mips/mach-mips/mc146818rtc.h
../linux-2.6.18.1/include/asm-mips/mach-pb1x00/mc146818rtc.h
../linux-2.6.18.1/include/asm-mips/mach-rm200/mc146818rtc.h
../linux-2.6.18.1/include/asm-sh/mpc1211/mc146818rtc.h
../linux-2.6.18.1/include/asm-um/arch/mc146818rtc.h
I have tried explicitly including the asm/um and the asm/arch versions
at different times with no success.
Any help will be valuable to me.

I'm am trying to get NistNet (http://snad.ncsl.nist.gov/nistnet/)
working in VNUML (http://www.dit.upm.es/vnumlwiki/index.php/Main_Page)
and am having some problems which I'm not sure how to fix. NistNet is
quite a cool tool to front-end Linux traffic shaping using "tc" etc. I
have it working on some systems but for a student exercise getting it
going from inside VNUML would be ideal. VNUML is light weight and we
can give students root access safely. But the exercise needs NistNet
to compile + run using a VNUML Kernel!
*Has anybody used NistNet with VNUML?*
If so which version?
What kernel?
How did you do it?
My host is running Fedora 8 with kernel 2.6.24.5-85-fc8.
My vnuml runs 2.6.18.1-bb2-xt-4m inside a debian like setup - the
default VNUML 1.8.3 I think
I have so far tried using the 2.6.18.1 kernel in the VNUML install I
have. I compiled the kernel + modules on my host with ARCH=um. Then
tried to build NistNet. Had to modify the "configure" file to make it
pick up the correct kernel - default uses "uname -r". I also had to
modify the NistNet kernel package's Makefile (not generated by the
configure) to also pick up the correct kernel headers.
So I tried a kernel from the range the NistNet site says should work,
selected to coordiate with working VNUML kernels - I picked 2.6.10.
But this has compile errors and I have not spotted any patches for it.
But I got lots of errors I do not understand.
I also had a go at building the kernel inside a running VNUML but did
not get very far as the point of VNUML is to keep the system small and
so much was missing....anyway, it did not seem easy.
Any help or advice would be gratefully received.
With thanks
