I'm trying to verify that my inline specification is correct:

If have a function declared as inline both in the class header file in the .cpp file where it is defined, I get the following warning when compiling any module that calls this function:

Warning from compilation:

test.h:977: warning: inline function `long myClass::getState() const' used but never defined


Header file declaration:

inline long getState();


Function definition in C++ module:

inline long myClass::getState() {
return currentState;
}


When I remove "inline" from the header prototype I get no warning:

I assume this is correct (?) Is there any way to verify that it is actually inlined by looking at the object file using nm or something?

Thanks for any help,
Mike

see http://www.dsprelated.com/groups/c6x/show/7531.php

To summerize: You will need to move the function definition to the header file. Or what you can do is in the .cpp file or similar where the inline function is encapsule it with

#ifdef INLINE_INCLUDE
inline functions ....
#endif

#ifndef INLINE_INCLUDE
non-inline functions...
#endif

then in your header file
#define INLINE_INCLUDE
#include "cppfile"
#undefine INLINE_INCLUDE

and remove the prototype in the header file. I think that should work.

...interesting, I hadn't thought of that--isn't that kind of unconventional in that it goes against the strictest sense of what a header file is?

If I remember correctly, i think i read to include the function definition in body of the class definition. Sound okay too?

Thanks again,
Mike

Sorry, I get it. What your mentioned in your initial reply (2) is exactly what I was talking about and didn't realize:

"include the function definition in body of the class definition"...

I probably should have said the "class declaration" to be more accurate.

Thanks,
Mike
