RE: [Xen-users] Xen-dom0 kernel compilation in fedora 9

[Sreeharsha Totakura <sreeharsha.totakura@xxxxxxx>]

Hi Pallab,

The problem was with mercurial executable. I didn't have mercurial 'hg' in
my computer and the 'make dist' needs a linux-2.6.18-xen.hg repository to
compile the kernel. I installed mercurial and the compilation is going on
now. Thanks.

The Xen 3.3.1 downloads page http://www.xen.org/download/index_3.3.1.html
is bit confusing for me. Can anyone tell me the difference between the two
download packages (linux-2.6.18-xen-3.3.0 and xen-3.3.1) listed in the page
apart from the size? The README documentation of those packages seem to be
the same for both.

Subject: [Xen-users] Xen-dom0 kernel compilation in fedora 9


Hi,

I am trying to compile Xen dom0 kernel in fedora 9.

I have downloaded 2 packages: linux-2.6.18-xen-3.3.0 and xen-3.3.1.

>From the xen 3.0 documentation, I understood that the xen-3.3.1 package
has
the xen-binaries. But, when I try the ./install.sh script it complains
that
there is no 'dist' folder to install. So, I have tried 'make world' and it
complains that it can't find linux-2.6.18.hg (unable to determine path to
Linux source tree) and quits. Exact error o/p below:

      make[2]: Entering directory
`/home/harsha/Download/Xen/xen-3.3.1-try'
      set -e ; \
            if [ ! -e linux-2.6.18-xen.hg/.hg ] ; then \
                __repo=$(sh buildconfigs/select-repository
      linux-2.6.18-xen.hg .:..) ; \
                if [ -d ${__repo} ] ; then \
                    echo "Linking ${__repo} to linux-2.6.18-xen.hg." ; \
                    ln -s ${__repo} linux-2.6.18-xen.hg ; \
                else \
                    echo "Cloning ${__repo} to linux-2.6.18-xen.hg." ; \
                    hg clone ${__repo#file://} linux-2.6.18-xen.hg ; \
                fi ; \
            else \
                __parent=$(hg -R linux-2.6.18-xen.hg path default) ; \
                echo "Pulling changes from ${__parent} into
      linux-2.6.18-xen.hg." ; \
                hg -R linux-2.6.18-xen.hg pull ${__parent} ; \
            fi
      select-repository: Searching `.:..' for linux-2.6.18-xen.hg
      select-repository: Ignoring `.'
      Unable to determine path to Linux source tree.
      Falling back to linux-2.6.18-xen Mercurial repository.

      /bin/sh: line 8: hg: command not found
      make[2]: *** [linux-2.6.18-xen.hg/.valid-src] Error 127
      make[2]: Leaving directory `/home/harsha/Download/Xen/xen-3.3.1-try'
      make[1]: *** [linux-2.6-xen-install] Error 2
      make[1]: Leaving directory `/home/harsha/Download/Xen/xen-3.3.1-try'
      make: *** [install-kernels] Error 1

Having no luck with xen-3.3.1, I tried compiling linux-2.6.18 with
the .config file which came with my distro: make oldconfig. It asked me to
configure some new options and I selected the defaults for them. Now when
given 'make' it stops with the following error:

      kernel/built-in.o: In function `timespec_add_ns':

/home/harsha/Download/Xen/linux-2.6.18-xen-3.3.0/include/linux/time.h:175:

      make: *** [.tmp_vmlinux1] Error 1

The documentation for Xen3.0 compilation doesn't seem to be of much help.
Which package should be compiled for getting the dom0 kernel?
