Actually showing us the code would be better.

Ugh... Don't use /* to disable code. Use the #if. Comments don't
nest so if you inadvertantly add another /* */ style comment some where
you'll get a surprise.

I suspect that FramedSource is not defined at this point based on the
compiler error. While it appears that the FramedSource.hpp (the second
time it appears) should be included, the include guards are highly suspect.

I sometimes resort to a dodge to determine if code is actually getting
compiled or not in light of lots of #if and #include usage.

I stick crud like:

2.2.2.2

which is syntacitally invalid in places I wish to see if they are
reached. If I get an error about it, I know I got there.
