[Xen-users] xen-4.0-testing.hg - Debian vs Redhat layout patch options

[user virtual <virtualusr@xxxxxxxxx>]

Hi Guys !

I am forwarding my latest experiences for building xen-4.0.x releases on debian based systems (ubuntu 10.04).

I find the following patches missing in xen-4.0-testing.hg :
- backport-StdGNU.mk.diff  (from xen.unstable)

- backport-blktap2-libs.diff  (from xen.unstable)
- debian-sysconfig-default.diff  (my personal, dirty, but non-intrusive solution for non-debian systems)

Issues for Debian package maintainer: 
- After you apply backport-StdGNU.mk.diff debian/rules must include line


export LIBLEAFDIR_x86_64 = lib
- Python modules get correctly packaged in debian/rules by using command dh_pysupport
- In order for debian package builder command 'dpkg-buildpackage' to succeed the "env -u LDFLAGS" must be used in debian/rules makefile on two commands:

env -u LDFLAGS make install-xen
env -u LDFLAGS make install-stubdom

An issue for anybody trying to build-install without debian packages by 'make dist; make dist-install'. Python modules get installed to the wrong path by default. This can be resolved by either:

- (my personal, dirty, but nonintrusive solution) applying patch debian-python-2.6.diff after previously applied the above debian-sysconfig-default.diff
- (xen developers suggestion, not running personally) run make as 'PYTHON_PREFIX_ARG="" make dist'. Builds ok and installs python modules under /usr/local/lib/python2.6/dist-packages.

I suggest applying the above three patches to the xen-4.0-testing.hg. At least the first two should pose no problem as they backport working solutions from the coming xen version. I am not missing debian-python-2.6.diff personally, as I always build packages, but there might be other opinions out there.

Resolving the above issues related to the attached 4 patches makes xen-4.0-testing.hg 100% debian compatible; well, according to my personal experience. 

For an example of debian packager script see:
