Hi Robert,

It was good to know.  If you need exactly ecos-3.0 ecos.db, then you can
grab the original from Web:
http://ecos.sourceware.org/cgi-bin/cvsweb.cgi/ecos/?cvsroot=ecos

scroll down and set:

 Show only files with tag [ecos-v3_0-release  ] [Go]

and download the wanted ecos.db.

NOTE: ecos.db sources itself if you manage eCos packages (add, remove,
packages), so, backup original ecos.db, "diff" it with new one and
adjust addons/rejects using your $EDITOR (in 90% you need to append new
package/target definitions at the end the original ecos.db).

About build error. Perhaps, that's *v3_0* vs *current* mess. Start build
in new fresh directory then.
