Hi,
This is a known problem, coming from the fact that the Eclipse indexer (that analyses all files in your new project) runs in background; if you open a file before it has finished indexing all files it may not yet have indexed the files where these symbols are defined, so it signals errors...
To solve that you just have to force rebuilding the index, by right-clicking on any file in your project in the Project Explorer view then selecting “Index >> Rebuild”; the errors should then disapear after some seconds. If they don’t, just delete them from the “Problems” view and they should no more appear.
Hope this helps,
