Undefined Symbol...

Do you have all headers in place?

Unable to debug... Yeah, it is hard to debug if your application does not even build.
Check the .lib files required for the classes appearing in the error messages (I have highlighted them for you), you can use the on-line documentation too (http://library.forum.nokia.com), and add them to the .mmp file.
Note that console code has no CCoeEnv, it may or may not be a problem, depending on what you are doing exactly. For example CCoeEnv::Static()->FsSession() is giving you an RFs, which you can create and Connect yourself

RFs fs;
User::LeaveIfError(fs.Connect());
