Could you fix your mail client, please? Your message has problems with line 
endings, which makes it nearly unreadable.

Well, the compiler tells you what the problem is, just read the errors 
carefully. It's not about linking, actually.

The compiler is telling you that it can't find 'lex' in the global namespace. 
Either you forgot to prepend it with 'boost::spirit::' or there's a missing 
using declaration or namespace alias.
