error:not a class

[yeah]

Hi friends,

i am new to c++ programming,when i compile c++ program got the error
as " not a class or struct name .I added all the headers files it
asked when compiling, but still getting error.
suggest me any idea that where i would have done wrong.

Error Report::
"RTPSource.hpp", line 49: cc0262: error: not a class or struct name

PLease explain me generally why this error occurs..

Any help in this would be appreciated.

thanks&regards

Actually showing us the code would be better.

/*#ifndef _FRAMED_SOURCE_HPP

#include "FramedSource.hpp"

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.

> class RTPSource: public FramedSource

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.
