Sorry for taking so long to reply.  My kids robot building team has 
taken up all my free time.

In order for the tools to find "SomeClass", the symbol needs to be 
findable in your code.  There are a few ways to trick the parser into 
missing your class, the easiest of which is to use C macros to create 
your classes, or to hide your definitions in:

#ifdef SOMEVAR
class SomeClass ....

#endif

and not have the parsers macro table set up correctly.  (See 
semantic-lex-c-preprocessor-symbol-map or 
semantic-lex-c-preprocessor-symbol-file, or preferably use EDE (the 
project system) to restrict those variables to a specific directory only 
using `ede-cpp-root', or `ede-enable-generic-projects' and then using 
`customize-project'.

If SomeClass is in a namespace, and you have a using statement, try 
moving the using statement into the same file as the code you are trying 
to edit.  I thought it worked from headers too, but maybe your headers 
have some macro excitement around your using statement too.

I hope this helps.
