Bharat Bhat asked us the very same question on Monday, and I explained
to him:

| Well, this is a pretty clear error message isn't it? The

I also pointed out:

| This helps to prevent such errors.

Bharat Bhat asked this before, too, and I replied:

| You must of course use the respective files from the ELDK installation

The solution in your case reequires several steps:

1) Read the documentation:

2) Download the ELDK (unless you already have received it on CD with
   your 460EX board)

3) Install the ELDK. Follow the documentation step by step.

4) Copy the C++ libraries from your ELDK installation tree to your
   target root file system. If you use the recommended installation
   directory "/opt/eldk/", then the C++ libraries can be found in
