Unable to build. :)

Hi,

I'm aware that 0.4 should be out soon, but in the meantime I've tried
to build a current git version and when building with default options
I get:

Building userspace libraries...

and when trying to configure with any options different than defaults I get:

TypeError: cannot concatenate 'str' and 'NoneType' objects

or some other python errors.

Judging by the date of the last commit the version in the git is
outdated. I enjoy codezero from the technical point of view, but with
stuff like that it would be hard to gather any community around this
project.

Kudos,
Dawid

Codezero future plans.

2010-11-27 Thread d...@ucore.info
Hi,

I'm wondering about the future of Codezero project.

I recently bought a BeagleBoard-xM board and I have strong motivation
to start doing something low level with it. I've already did some
toying and learning to get into the subject and now I'd like to start
doing something more useful. Ideally I'd like to develop a L4 kernel
and if the fate allows connect it with my professional life. I have
some embedded and Linux kernel experiences and quite a lot of
theoretical and practical knowledge about low level programming and
this is what I'm passionate about.

And I'd really like to work with a Codezero as a starting base and
just add my own things on top of it, but I'm unsure about how this
project is going to be handled in the future.

I really love how the Codezero is written: good plain C, well written
self explaining code, etc.  I dislike C++ and all L4 implementations
around except for Codezero throw me off at the beginning. However I
can see that current development of Codezero is being done ,,in the
shadows'' with read-only releases to the Open Source community.
Current git repository is 5 months old, the project status is unknown,
on the development mailing list I can see only mails about releases
and no discussion about technical concepts or development status. And
the current git version does not even properly compile and have broken
config scripts.

It seems that because of B Labs. business reasons (which may be a fair
and valid, but unknown to met) and the immaturity of the project (fast
development pace) even if I create any changes there is a low chance
it will be anything really useful.

I could just start my own project which would be good for learning
purposes and just steal bits of code from codezero, but this seems
like a real waste. I'm perfectly aware that creating anything really
useful as a part-activity in a single-man project is hard and I'd like
to avoid it.

So, are there any information on where can we expect Codezero 0.4
release and is there any chance for more collaboration inviting
development model of Codezero? Honestly guys, what do you think?

Regards,
Dawid

Hi Sebastian,

I'm afraid Wifi on PandaBoard is not supported as it was not tested
and probably not even configured in guest kernel.

For networking, please use the onboard LAN port.

I have no way to test this ATM, but I think the ethernet was
DHCP-enabled in the demo.

If it's not, you must hack Android init script for this to work or
issue the neccessary commands yourself:

http://ask.linaro.org/questions/508/how-to-configure-ethernet-on-linaro-landing-for-pandaboard/522

If anything requires root access, you should use "su" command.

Also, in case of reporting any issues, please paste the exact output
that you're getting on the console. A advise using serial cable to
Panda's outputs and shell.
