Building coreOS for power linux arch : "ppc64le"

[Amit Ghatwal]

Hi All ,

I am new to coreOS , I was trying to build coreOS – SDK from below link :

https://coreos.com/os/docs/latest/sdk-modifying-coreos.html , While building an image with step “./chromite/bin/cros_sdk “ , I am getting below errors :

“cros_sdk: error: cros_sdk is currently only supported on x86_64; you're running ppc64le.  Please find a x86_64 machine “  . I am a newbie to porting open source packages.

 Please let me know the way forward /steps to port it on ppc64le architecture.

I am interested in porting coreOS onto a new architecture ( ppc64le ).

# lscpu

Architecture:                                     ppc64le

Byte Order:                                        Little Endian

CPU(s):                                                 2

# lscpu

Architecture:                                     ppc64le

Byte Order:                                        Little Endian

CPU(s):                                                 2

Regards,

Amit

Porting (and maintaining!) an entire operating system to another
architecture is going to be a lot of work. Unless you have a small team
of people who are willing to put in a few months of work, it probably
isn't going to happen. Even more problematic is the fact that this port
will invariably take up a lot of our time as well (which we are already
very short on).

Unfortunately, my suggestion is that you run CoreOS on an AMD64 box for
now.

CoreOS is cross compiled. This tells you that you cannot
host the CoreOS build on anything but an x86_64 machine.

You MUST build CoreOS on an x86_64 host machine.

This is a big job, and based on your mail, I would say
too big a job for you.

If you want to consider it, I recommend you start with
what to do about Gentoo's lack of ppc64le support. Is
the first step to port Gentoo to ppc64le? Will the
CoreOS maintainers accept all the work-arounds needed to
support an architecture that Gentoo does not yet support?

Hi Geoff,

Thanks for your reply.

I was trying your said approach of firstly porting Gentoo onto Ubuntu14.04/ppc64le platform . I am following below link for the same

Link : https://wiki.gentoo.org/wiki/Porting

But on running the very first command ( to install portage ) , I am getting below

$ ./bootstrap-portage
Setting up initial environment
Please set ARCH

Any pointers how to resolve/install Gentoo/portage on ppc64le ?

Regards,

Amit

My best advice would be to ask on the gentoo mail lists.
