xenolinux compilation error

xenolinux compilation error

[Carlos Alberto Pereira Gomes]

Hi,
I've got some problems while compiling a linux-2.4.25 kernel patched
with xenolinux-2.4.25-sparse tree.

The command 'make dep bzImage' stops at:

....

mm/mm.o: In function `clear_page_tables':
mm/mm.o(.text+0x12b): undefined reference to `XEN_flush_page_update_queue'
mm/mm.o: In function `pte_alloc':
mm/mm.o(.text+0x17c3): undefined reference to `XEN_flush_page_update_queue'
mm/mm.o: In function `move_page_tables':
mm/mm.o(.text+0x80b6): undefined reference to `XEN_flush_page_update_queue'
mm/mm.o(.text+0x80df): undefined reference to `XEN_flush_page_update_queue'
mm/mm.o: In function `unuse_process':
mm/mm.o(.text+0xd630): undefined reference to `XEN_flush_page_update_queue'
fs/fs.o(.text+0x98eb): more undefined references to `XEN_flush_page_update_queue' follow
make: ** [vmlinux] Erro 1


Has anyone got this?
Any idea?

The auto build daemon successfully built both the 1.2 and
unstable trees last night, so I think it must be something odd
about how you're building it.

Are you using a vanilla linux-2.4.25 tree as the base?
Did you follow the instructions for running mkbuildtree correctly?
Have you modified any of the kernel configuration parameters?
Are you remembering to set ARCH=xen ?

I'd expect the appended sequence to work (from the xen-clone
script).

Ian


tar -zxf linux-2.4.25.tgz		# untar the vanilla build tree

cd xeno.bk/xenolinux-2.4.25-sparse	# cd into sparse tree in repo
./mkbuildtree ../../linux-2.4.25	# patch the vanilla tree
cd ../..
mv linux-2.4.25 xenolinux-2.4.25	# rename to reflect change

cd xenolinux-2.4.25

make ARCH=xen oldconfig			# use default config
make ARCH=xen dep			
make ARCH=xen bzImage			
make ARCH=xen modules			# build modules if required

# you may then find the 'install' or 'dist' targets useful.

A question on xen-1.2??

[I RATTAN]

I have been able to compile and boot xeno-linux-2.4.24-xeno (used
linux-2.4.25 generics sources this time).

I see two messages at boot, parts of dmesg shown:
---
Linux version 2.4.25-xeno (root@pe-dyn221.cps.cmich.edu) (gcc version 3.3.2 20031022 (Red Hat Linux 3.3.2-1)) #1 Thu Apr 1 15:39:11 EST 2004

-------------

Also, if the box is rebooted then there is a message
...
Syncing hardware clock to system time modeprobe: Can't locate module \
char-major-10-135

What module is that?

And the machine needs a hardware reset to reboot (as ti just sits there!)

This a Celeron based PC with Fedora-core-1 underlying system.

Are you intentionally trying to use an initrd ram disk?  If so,
what's in it?  Why is it so big? (this is a linux issue, not a
Xen one)

I'll bet this is some random ioctl to do with audio on a
CDROM. We should figure out which one it is and add it to the
list that we ignore without grumbling about (or add support if it
might be useful). Stuff like this will go away in the new IO
world anyhow.

Probably the RTC driver. You don't want to use it with Xen
anyhow, so just disable it. (either remove the line from the rc
scripts, or you may be able to alias it to null in your modules.conf).

Odd. Are you booting with 'noreboot' on the Xen command line?

Interestingly it only 98K initrd..
In linux domain initrd of 1600K are working (initrd-2.4.22-1.2115,nptl.img
for uniprocessor kernel under Fedora).

> Odd. Are you booting with 'noreboot' on the Xen command line?
Yes, I am.

Thanks for the responses.

It looks like Linux is seeing it as a huge initrd. 

What version of Xen/Xenolinux are you using? Can you reproduce
the problem using binaries from either the CD or the nightly
builds?  (the boot messages suggested that you were building your
own). Is this a domain 0 boot or another domain?
