Re: [Xen-users] Xen unstable fails to build on ubutnu 12.04

[Kristian Hagsted Rasmussen <kristian@xxxxxxxxxx>]

Hi

I had this problem, and found a patch here. 
http://lists.gnu.org/archive/html/qemu-devel/2012-02/msg03460.html
Which I applied manually. It seems to be a problem with the gcc version.

Best regards Kristian

Emne: Re: [Xen-users] Xen unstable fails to build on ubutnu 12.04

humm, well that sucks. I know compiling changeset 25392 works for me, with the 
packages and instructions i described, i have compiled it several times now. I 
know the main reason why the later changests won't compile is because of the 
different GCC version seem to do different enough to fail, SO maybe Ubuntu has 
a different subset of GCC. I have no idea.

Well, if it was no trouble for you, maybe try to install Debian Wheezy and try 
to compile again. Otherwise i could always send you the Xen 4.2
rev-25392 compiled DEB package and you can just install that, BUT that wouldn't 
solve your problem if you wanted to compile it later on.
