[Xen-devel] Latest xen-unstable does not compile

Hello!

The latest xen-unstable (changeset:20345:e74a1223a09c) does not  
compile for me. It stops during retrieving linux-2.6-pvops:

Just did a ''hg pull && hg update && make

wrong? Is linux-2.6-pvops not supported any longer? What must I do to  
get a ready to use xen-unstable with 2.6-pvops?

(Environment: Debian 5.0.1 on i686).

Kind regards

Andreas

If you revert c/s 20296, does it then work for you? Reverting that changeset
will cause you to grab the Linux tree via git protocol rather than http.

Re: [Xen-devel] Latest xen-unstable does not compile

Hu - I like to answer my own mails...

After ''make world'' stops and after sending the bug report - I
did a
''make dist''. And: it compiled - and boots - and xm-tests are
running.

I''ll start all over tomorrow and check the build problem again.

Kind regards - Andreas

Re: [Xen-devel] Latest xen-unstable does not compile

Hi Andreas,

Why don''t you do compilation of xen-unstable and pvops kernel
separately?

E.g.

Compiling xen-unstable
===================
prerequisites: install pciutils and pciutils-devel first
>From Boris'' instructions (adapted to your case):
# hg clone http://xenbits.xensource.com/xen-unstable.hg
# cd xen-unstable.hg
# make xen
# make install-xen
# make tools
# make install-tools

Compiling pvops kernel 2.6.31.1
==========================
Also from Boris'' instructions:

# git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git
linux-2.6-xen
# cd linux-2.6-xen

No need to do a checkout at all as the default is xen/master and at
the moment it is pvops 2.6.31.1 if I am not wrong.

Then my own steps:

# make mrproper
# vi Makefile # change the extraversion string

Try my 2.6.31.1 xen pvops kernel config as attached in this email and
rename it to .config in linux-2.6-xen/ source directory

Then

# make oldconfig

For any NEW kernel features, just accept the defaults by pressing ENTER

# make
# make modules_install
# make install

Then edit your grub configuration to reflect your newly installed Xen
pvops dom0 kernel. You need to use a kernel and two modules statement
instead of the conventional kernel and initrd statements.

Nice complete set of instructions. One change added below.

I would add one modification to the Xen build here. Since you''re
building the 2.6.31.1 kernel separately there''s no need to build the
default xen kernels, so you can disable that part of the build with:
export KERNELS=""

I also like to build the xen deliverables in a location that is easily
installable to other targets:
export DISTDIR=/install-from-location (some shared filesystem)
# make dist

Then from each target:
cd /install-from-location
install.sh

> # make install-xen
> # make tools
> # make install-tools

Re: [Xen-devel] Latest xen-unstable does not compile

Hi!

Started all over with c/s 20346:d7d7f978d704: it works perfect -  
everything compiles (only the questions are annoying...).

Please ignore my previous post about a compile error during a ''make  
world'' - looks that some relict had some influence on the build  
process. Sorry for this.

Kind regards - Andreas

Hello!

Because I''m lazy and IMHO the makefile should do it better than I can  
ever do :-)
