Due to the renewed interest in Embedded Gentoo, we're looking for some
people that are interested in helping get it restarted.  There are
already a few devs intersted in helping out: solar, sindian, abhishek,
and myself.  The #gentoo-embedded channel has been re-awakened.  Dejan
has already sumbmitted a proposal, but before we start any projects, we
need to do some planning.  Having an IRC meeting seems like a good way
to get the ball rolling.  So if you're interested in helping out, or
have some ideas, let us know.

I'm a bit short on time at the moment (hopefully will have more in Dec), 
but I'd be interested in working on this project also if there's any 
small things that I could do...
Is there a list of devices we'd be concentrating on yet? I'd be 
interested in running such a distro on my Zaurus SL-C760. Also, ideas 
for GUIs might be spyderous's <1MB X11 server and Opie. Don't think we 
can fit KDE/GNOME into the 64MB tho ;)

Well i think the idea was to get it working on "real" embedded software
as oposed to PDAs and concentrate on getting the base system as small as
possible before any other ebuilds are modified for size.

You can fit a fairly complete installation of kdrive and needed
libraries into ~7MB after deleting a few unneeded servers. However that
isn't in portage right now, just my overlay, which is available on
http://dev.gentoo.org/~spyderous/overlay/.

The kdrive in portage currently should also work somehow but is older
and the build is significantly different (imake vs. autotools).

Well what we're looking at right now is to see if we can get some people
to work on the project, so it can actually restart.  So after that, we
need to plan project scope, subprojects, etc.  But handhelds would
certainly be in there.  I know sindian and myself would be looking at
that.  I'd probably pick up a zaurus or ipaq.  I'd like to put SELinux
on it. :D  (Before you say boo, the debian/redhat SELinux guy has it on
his ipaq)

I've got an ipaq with linux on it, would rather it be gentoo =)
Just need to get me one of the adapters for pcmcia so I can get wireless
to it I suppose!

hi,

i'm fairly new here, but monitoring this group for quite some time.
i really would be intersted to get such a project up and running for my
zaurus SL5500G
just to let you know

I put up a rudimentary draft project page:

http://dev.gentoo.org/~pebenito/embedded.html

Really whats to note is the subprojects, which is just my idea of how
things are laid out.  Everything on the page is pretty much open to
discussion (esp. since there isn't much).

It appears that the gentoo-embedded mail list is (still) available.  I
invite everyone thats interested in the project to subscribe.  Then we
can move the discussion there, and really get things started.

I second that.  Although seemless cross-compilation would be a good
first step ;-)

what's needed by portage for this type of a thing to work ?  Lots of
re-design ?

For automatic discovery of distributed cross compiling nodes, take a 
look at my zeroconf service lookup/announcement implementation on 
http://dev.gentoo.org/~pvdabeel/.

The idea of zeroconf distributed cross compilation is similar to 
Apple's Xcode implementation:

When somebody announces a service, zeroconf A, SRV, TXT and PTR DNS 
records are created:

The A record contains the IP addres on which the service is available.
The SRV record contains the PORT on which the service is available.
The TXT record contains additional info about the service in a hashmap: 
Apple Xcode for instance encodes the gcc version, the Os version, ... 
(screenshot on http://dev.gentoo.org/~pvdabeel/xcode.jpg)
A PTR record announces a service by a unique name, using that unique 
name A,SRV and TXT can be looked up.

A lookup is basically a retrieval of PTR records for a given category. 
(for instance: _http._tcp.local. gives all http tcp services, 
_distcc._tcp.local. returns the different tcp distcc services on the 
local net).
My tool also allows one to announce your Linux webserver using zeroconf 
etc (http://dev.gentoo.org/~pvdabeel/browser.jpg) and discover those in 
your Zeroconf compatible browser.
If you want to experiment with the tools, please read their usage(). 
Those should contain enough examples. Some fun stuff:

Lookup _http._tcp.local. pointers on a university network with lots of 
Zeroconf printers/machines available:

root@research ZeroConf # ./lookup 12 _http._tcp.local.
PTR _http._tcp.local. to HP LaserJet 4100 Series 
(0001E67C7BFC)._http._tcp.local.
PTR _http._tcp.local. to Wnt CEGE._http._tcp.local.
PTR _http._tcp.local. to HP LaserJet 2200 
(0001E69C3074)._http._tcp.local.
PTR _http._tcp.local. to hp LaserJet 2300 series 
(0001E6A194BB)._http._tcp.local.
PTR _http._tcp.local. to HP LaserJet 3330 
(0001E6918AB2)._http._tcp.local.
PTR _http._tcp.local. to hp LaserJet 2300 series 
(0001E6A6E82B)._http._tcp.local.
PTR _http._tcp.local. to hp LaserJet 2300 series 
(0001E6A1B6D8)._http._tcp.local.

Typical usage:

Announcing a service:

root@research ZeroConf # ./announce 'pvdabeel' 134.184.65.92 1234 'This 
is cool' distcc
Zeroconf announcing 'distcc' service named 'pvdabeel' with ip 
134.184.65.92 on port 1234 and extra arguments 'This is cool'

Looking up services:

# Getting pointers to available nodes
root@research ZeroConf # ./lookup 12 _distcc._tcp.local.
PTR _distcc._tcp.local. to pvdabeel._distcc._tcp.local.

# Use a pointer to get an IP
root@research ZeroConf # ./lookup 1 distcc-pvdabeel.local.
A distcc-pvdabeel.local. to ip 92.65.184.134

# Use a pointer to get a PORT
root@research ZeroConf # ./lookup 33 pvdabeel._distcc._tcp.local.
SRV pvdabeel._distcc._tcp.local. to distcc-pvdabeel.local.:1234

# Use a pointer to get the extra arguments
root@research ZeroConf # ./lookup 16 pvdabeel._distcc._tcp.local.
TXT pvdabeel._distcc._tcp.local. contains args=This is cool

Cool. I'm also an OS X & Linux user, and it sounds like you're working 
on some of the features I'm really interested in. I'd really love to be 
able to use my DP G4 (running OS X) to compile stuff for my PC Linux 
boxes.

I'm also very glad to see an implementation of ZeroConf / Rendezvous 
for Linux, although i don't know yet what I might do with it. Any 
chance of an ebuild..?

Do let me know (perhaps via the gentoo-osx@gentoo.org list?) if you 
need any testing doing.

Stroller.

I think that indeed it would be nice if someone could pickup where gcc-config 
left when zynot was created. I would also hope that in the future portage 
would support paralel installation of packages of the same version (if 
supported by that ebuild)

That's a giant leap. I had a looking at setting up a cross-compilation tool 
chain. Wasn't pretty. Basically I made a big mess and it didn't work. If 
anyone else wants to work on this I'd be interested in helping. I have x86 
and pcc so I can test things properly.
