[Xen-devel] Re: [Xen-users] xen pae build is broken on ubuntu dapper

[Hans-Christian Armingeon <johnny@xxxxxxxxxx>]

Hi,

I know, this issue looks like, if I'm totally noob.

I usually build kernels and software as an unprivileged user. And this works 
fine in my sarge chroot, but not on dapper!

Take a xen unstable snapshot, and run these commands:
XEN_TARGET_X86_PAE=y make kernels XEN_TARGET_X86_PAE=y

cd linux-2.6.16.13-xen 
sudo make modules_install

This is the way, I usually did it.

Between the two //, there should be a variable (the installation path), which 
is correctly evaluated, if I'm inside the sarge chroot.

When I ahvent set XEN_TARGET_X86_PAE=y, and I run make xen tools as an 
unprivileged user, the files get installed in $PWD/dist/install/usr/lib .

make xen tools as an unprivileged user:

I stated in a previous post, that I think that the newer version of make on 
dapper is the culprit.

I dont feel offended by the two answers I got, that might look like I'm too 
stupid, to build xen. ;-)
