building busybox with ELDK

Hi I want to build a root file system for embedded Linux running on the
powerpc440 of Virtex-5 FX30T using busybox. I'm using ELDK 4.1 with Colinux
fedora core 5. can anyone please tell me how I can build busybox with ELDK.
I have successfully  cross compiled a Linux kernel for the powerpc440 and
used the root file system of ELDK ppc_4xx. It worked fine, now I'm trying to
make a customized root file system from busybox.  I would appreciate any
help.. thanks in advance

You may want to read the documentation - see for example
http://www.denx.de/wiki/view/DULG/ELDKRebuildingComponents#Section_3.8.2.

Questions wrt embedded web server

That depends on what you are doing. There are good reasons for making
extensive use of interpreted languages on embedded platforms. For
instance robustness and reliability, only to name two.

What exactly are you trying to do? Rebuilding the ELDk from scratch?
Running in a recent Linux distribution (i. e. not using the "official"
RH-7.3 based build environment) ?

Best regards,

ELDK 4.2, fedora 10, libdw fails w/redefinition error

Hello,

 Yes, I am trying to build the ELDK from scratch on a new fedora 10
install.  However, after doing some more searching I found a patch for
version 128 of elfutils which fixes this gcc problem. I've now made it
to target 32(module-init-tools) before failing again.  Just wanted to
see how well things worked on fc10 but we are going to try to RH vm
also.

thanks,
jeff

If you have any such patches, please post them here (or send them
directly to me) so we can add them to the repository.

Thanks in advance.

If I don't document something, it's usually either for a good reason,
or a bad reason.  In this case it's a good reason.  :-)
