ppc

[Peter Czanik]

Hello,

I got now a bit stronger PPC machine standing next to my desk (
http://en.opensuse.org/MPC8610 ). This brought me the idea, that I
should recompile some buildservice projects for PPC (like:
http://download.opensuse.org/repositories/X11:/Enlightenment/ or
http://download.opensuse.org/repositories/KDE:/KDE4:/UNSTABLE:/Desktop/ 
). Before trying it myself I read some of the documentation, but I still
have a couple of questions:

- does the buildservice work at all on PPC?
- if yes, is it a simple recompile of all files at
http://ftp-1.gwdg.de/pub/opensuse/repositories/openSUSE:/Tools/openSUSE_11.0/src/ 
on PPC?
- is it possible to check out a project from BS, like
KDE4:/Unstable:/Desktop and recompile it locally for PPC in one go? I
mean, without needing to compile individual source rpms one by one and
needing to figure out the build order...

Bye,
CzP

Do I understand well, that you use x86 machines to compile PPC?

Is
http://download.opensuse.org/repositories/openSUSE:/Tools/openSUSE_11.0/src/obs-server-0.9.99-3.1.src.rpm 
equal to OBS 1.0 rc1? This is the latest version available as far as I
can see...

Anyway, I'm downloading it and trying to install it on my PPC machine...

Wow, did they make ANY PPC machines that are easy to install Linux on?
 Seems like they decided to make things way different for some
reason.... :(

Glad to have you helping out.

Yes, there are some of them. RS/6000 machines were easy, when I tried
them a couple of years ago, and Genesi boards are also no rocket science
to install :-) The board mentioned is not yet a production board, but an
evaluation board, a work in progress. I use it to check how SuSE works
with this CPU, and I'm quite impressed! It is just 1.3Ghz compared to
the 1Ghz of Pegasos ( http://www.genesi-usa.com/pegasos.php ), but
1.5x-4x faster, depending on application, while using less than 2/3 of
electricity. For example building the same kernel takes about 1/3 the
time. It has an unaccelerated framebuffer in the SoC, and it can still
play some of the 720p HD movies!

It just seems like you have to go through a lot more on a PPC machine
than an x86 machine.

How does it compare to a Core2 chip?  I'm running a Celeron DC E1200
1.6Ghz @ 3.2Ghz right now.  The FSB is running at 1600 Mhz.  The e600
looks like it only supports 533Mhz FSB.

I checked the web interface and also the wiki, but I could only find
examples for individual packages. How can I link a complete repository
in one go? For example everything from KDE:/KDE4:/UNSTABLE:/Desktop/
instead of individual packages in this repo?
