[ELDK] bridge-utils on ELDK 4.1

[Suresh Bhaskaran]

Thanks for your thorough response, Wolfgang.

I also noticed that on a couple of host systems, by doing a "ldd brctl",
that it depended on:

ldd -v /usr/sbin/brctl

        /usr/lib/libsysfs.so.1
        /lib/tls/libc.so.6
        /lib/ld-linux.so.2

And I noticed that the rootfs that I'm using (over NFS) does not have
these files.

Do you happen to know what packages I need to install in order for these
files to show up on /lib, /usr/lib and /lib/tls on the rootfs?

I am dealing with a working embedded system that has migrated from ELDK
3.x to ELDK 4.1, and is, perhaps, in some state in-between.  It is being
used by others in our user community, though, so the subset of
functionality needed so far in this kernel + rootfs-over-NFS
configuration is working.

I just need to get the brctl utility working on it.

Thanks!

If it's urgent, you may want to consider to hire an expert.

The free community help you can get here has no guarantee of being
fast.

You must not expect that this will actually work.  Your  Deb=ian  box
will  be  built with a different set of system libraries etc., so you
must assume thjat the binaries cannot be exchanged between Debian and
ELDK - at  least  you  have  absolutley  no  waranty  for  error-free
operation.

You mentioned this was with ELDK 4.1 - why are you using that old
kernel then? ELDK 4.1 comes with Linux 2.6.19.2 ...

To be safe, I recommend to rebuild the tools from the sources. If
cross-building becomes a problem, try building on the native system
(using the NFS root environment).

This is pretty likely, too.
