Hi, I am trying to install XCI. To my horrified, it tries to download and compile a lot of softwares, like binutils and even gcc 4.2.4. Is there any good idea to do that?? The problem is that binutils itself has some code not tested on gcc 4.3 on Ubuntu 8.10, and the compilation fails!

Because we use another libc we have to cross compiled environment, that why we compile binutils and gcc. If it doesn''t work with ubuntu you can still create a debian chroot.

It is not hard to fix the bugs of binutils, but I want to avoid messing with that if possible.

I know that the build works under debian, that why it will help.

I only way to reach that was to use busybox and uclibc. There is also newlib out there, but the buildroot project provide a build system that we can use directly. -- Jean Guyader _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Jun Koi wrote:> Could you explain how to "create a debian chroot" to avoid my > compilation problem?more generally, if you build environment doesn''t work: - you can use a debian lenny/squeeze VM to do your build. - you can create a debian lenny/squeeze chroot. i suggest, if you don''t know how already, to have a look at: https://wiki.ubuntu.com/DebootstrapChroot - send us patches to make our build system more friendly to other distributions. we certainly wish to have the system work everywhere (within reason), but lack some time to do that.

Note that you should be able to compile most of the trees (kernel, toolstack, ...) by yourself on any distribution, if you install everything that''s necessary. but it won''t be as easy and guaranteed to work as inside of our build. -- Vincent _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Hi,
I temporarily switched to Ubuntu 5.01, and succesuflly built XCI.
The HOWTO instructs to install the rootfs, then reboot the machine.
But what is the next step after that?? I suppose that after that, we
can boot Xen from the newly created rootfs??
BTW, I found that in the below step in HOWTO:
....
4 - Copy the rootfs inside the root LV:
$ bzip2 -d rootfs.i686.ext2.bz2
$ dd if=rootfs.i686.ext2 of=/dev/xenclient/root
(or alternately a remote push)
$ dd if=rootfs.i686.ext2 | ssh root@target "dd
of=/dev/xenclient/root"
....
The step "$ bzip2 -d rootfs.i686.ext2.bz2" not necessary, because we
already have rootfs.i686.ext2 inside binaries/xenclient/. So we can
remove that line.
Thanks,
J
