[Xen-users] Probs compiling open-iscsi and on xen-3.2.1 fedora-core8
Hi,
i try to compile open-iscsi on a system running a self-compiled xen3.2.1, but it
failed.
I think the problem is that xen3.2.1 uses two directories for building the xen-
and linux kernel.
The first directory contains only the vanilla linux-2.6.18.8 sources -
the other one (xen-3.2.1/build-linux-2.6.18-xen_x86_64) the objectfiles and
(copied ?) c-files ...
If i try to install open-iscsi like
wget http://www.open-iscsi.org/bits/open-iscsi-2.0-869.tar.gz #
tar xfvz open-iscsi-2.0-869.tar.gz
cd open-iscsi-2.0-869
make KSRC=/root/xen-3.2.1/xen3.2.1/build-linux-2.6.18-xen_x86_64
# or make
# or make install
# or make KSRC=/root/xen-3.2.1/linux-2.6.18-xen.hg
i got something like
make[1]: Leaving directory `/root/open-iscsi-2.0-869/usr''
make -C kernel
make[1]: Entering directory `/root/open-iscsi-2.0-869/kernel''
make[1]: *** No rule to make target `linux_2_6_'', needed by
`kernel_check''. Stop.
make[1]: Leaving directory `/root/open-iscsi-2.0-869/kernel''
make: *** [all] Error 2
If i manually correct this problem by changing kernel/Makefile, i got the next
error:
make[1]: Entering directory `/root/open-iscsi-2.0-869/kernel''
make -C /root/xen-3.2.1/xen-3.2.1/build-linux-2.6.18-xen_x86_64/ M=`pwd`

The problem is, that the new xen-3.2.x directory structure does not match the
directory-structure requirements
for open-iscsi...
Is there a way to compile it anyway ?
Here is the HOWTO to compile xen-3.2.1 (inherited from
http://lists.xensource.com/archives/html/xen-users/2008-01/msg00699.html). Maybe
someone who has more knowledge can try to compile open-iscsi against xen3.2.x:
yum install hgsvn
mkdir tmp
cd tmp
hg clone http://xenbits.xensource.com/linux-2.6.18-xen.hg
wget http://bits.xensource.com/oss-xen/release/3.2.1/xen-3.2.1.tar.gz
tar xfvz xen-3.2.1.tar.gz
cd xen-3.2.1
make prep-kernels
cp -av /boot/config-my-old-config build-linux-2.6.18-xen_x86_64/.config
make -j7 dist
make -j7 linux-2.6-xen-build
make -j7 install
make linux-2.6-xen-install
depmod 2.6.18.8-xen
mkinitrd /boot/initrd-2.6.18.8-xen.img 2.6.18.8-xen
# and modifiy /boot/grub/menu.lst like described in the xen-3.2.1/README
# and now ? compile open-iscsi (-: ...
