Hello World example for BitBake Manual

Hello World example for BitBake Manual

[William M.A. Traynor]

In researching and trying to work through a Hello World example for
inclusion in the BitBake Manual, I've been able to reproduce the
examples described in the following thread:
http://www.mail-archive.com/yocto@yoctoproject.org/msg09347.html

and in the following blog post:
http://hambedded.org/blog/2012/11/24/from-bitbake-hello-world-to-an-image/

Does anyone have sufficient knowledge of each of these examples to
comment whether they're "generic" enough for the manual?  I'm trying
my best to keep content as generic as possible, but it's proving to be
a struggle at times.

Specifically, I'm finding that it's possible to be to generic, and
thereby not adequately demonstrate the power of the tool.

Thanks
Bill

I think this example is generic enough for the documentation.

This however, whilst it is a very detailed and well written explanation, goes 
a bit further and is trying to put something together that's moving a bit 
towards what OE does, as an aid to explain how OE works (e.g. the introduction 
of an "autotools.bbclass"). I'm not sure this is really appropriate for the 
Bitbake manual IMHO. You could draw inspiration from parts of it though.

I know, it can be tricky. If you have specific areas you'd like help on then 
I'm more than happy to help though.

Excellent, I will use it as the basis for the manual content.

Thanks, I have many lately and will be posting them here.

Hello,

I tried to be comprehensive about how OE works in "From bitbake hello
world to an image" post. As Paul suggested, it would be detailed to
include in bitbake manual. However, I would be happy if it was
referenced in the manual :)

There are still some parts that need to be fixed in the document. They
are not show stopper but I haven't got time to fix them.

If you have any suggestions or questions regarding to the post, please
feel free to send an e-mail to me.

Regards,
Eren
