Yes, I would definitely suggest that you update to the CVS tree
(release 2.0 is nearing 5 years old!)

Once you've done that, I'd also suggest that you try some simple
things.  This sequence should work and generate a test that you
can try on your hardware:
  % ecosconfig new eb9261 net
  % ecosconfig tree
  % make; make -C net/common/current tests TESTS=tests/ping_test

Note: it's not clear to me why your tree has its own 'eb9261-net'
template as this should not be necessary.  Using .ecm files is
a much better approach.

n.b. of course you can do the steps above using the config tool,
but using ecosconfig is much more concise and easier to explain :-)

The eCos configuration I have appears to have the networking package included and yet when I attempt to link my application against the eCos libs I get several 'undefined reference' type errors. In particular:
