Re: [Xen-users] Compliling Xen 4.5.0 Fails

[Mark Pryor <tlviewer@xxxxxxxxx>]

You might have better results with

-- build as user, not as root

-- ./configure --libdir=/usr/lib --enable-ocamltools --enable-efi --prefix=/usr

-- move to 14.04 for the kernel better suited to xen 4.5

-- you might miss some build requires, so run `sudo apt-get build-dep xen qemu-linaro`

-- after `make dist`, you can create a *.deb via

   chmod +x ./tools/misc/mkdeb

  fakeroot ./tools/misc/mkdeb $(pwd) 4.5.0

the resulting *.deb is found in ./dist

Hi,


I get an error when trying to compile Xen 4.5.0 from source. It happens from the tarball and also from Git. I have tried it on two boxes with the same result (Ubuntu 12.04.5). I can compile 4.5.0-rc4 with no problems. I haven't looked at the differences in Git yet... was just curious if anyone else had had the same issue.


Any suggestions?

Apologies if this appears twice. I used an old list address to start with.

Thanks


Ian.
