problem 1) I have not yet cloned the linux tree, but there is a linux

What is this?
This is how the Xen guys track linux changes.
One day they will switch to a separate repo, and have started one,
but the migration is going slowly :)
for PPC please use the linux tree that the wiki (http://
wiki.xensource.com/xenwiki/Xen/PPC) refers to is is a child of the
separate repo I refer to above.
When I clone the linux repo. I guess I should use a
different name
you can use whatever name you want. it is a separate repo.
problem 2) do I have to clone linux and xen under the same root?
not at all. I do it cuz I have several linux trees and this one is
specific to linux work so I have
work/xen/xen-ppc
work/xen/linux/linux-2.6
work/xen/linux/build
Note that linux can be built separate from the source space (a very
nice feature)
for reference here is my build sequence:
$ make -C ~/work/xen/linux/linux-2.6 ARCH=powerpc O=../build
CROSS_COMPILE=powerpc64-linux- CROSS32_COMPILE=powerpc-linux- zImage
to config use the same line but replace "zImage" with
"xen_maple_defconfig"
If your default compiler is problematic (< V. 3.4.4?) then add
"CC=powerpc64-linux-gcc-3.4.4" or whatever the right compiler command
is.
I was able to build the cross tools on a machine with a bad
clock. I build 3.4.1 and not 3.4.4. That's what the script did.
Should I
have changed some other thing in the script?
Have not used crosstools in a while, I recall it being pretty
straight forward tho.
I was not able to build the cross tools on another, where Michal
upgraded
the native compiler to gcc-4.0. I am going to try and build the
tools with
gcc 3.3, if I can figure out how.
Do you suspect that gcc-4.0 cannot build crosstools? interesting you
should let the maintainer know this.
let us know how it goes.
