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

I cannot build xen for pae on ubuntu dapper with XEN_TARGET_X86_PAE=y make
kernels xen tools XEN_TARGET_X86_PAE=y

Can anybody tell me, where the problem is?

Johnny

You''re failing on the install-kernels target since you''re not
root (at
a guess). If you want to build a PAE kernel not as root just do: 

  - edit Config.mk in the top level to set "XEN_TARGET_X86_PAE=y"
  - in the top-level type ''make dist'' 

You''ll still need to be root to install.

cheers,

S.

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

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:

You see the double slash?

And here is teh "correct" version, where install copys thxen.gz into

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. ;-)
