Unless I'm mistaken, I believe that the definitions to inline functions need to be available to the compilation unit where they are being used. I believe this is specified as part of the ANSI C++ standard (although some compilers have extensions that allow what you are trying to do). This means that you either need to put the definition in the header file, or include the file that has the definition either into the include file or the source file where you are using the function.

Can this really do inlining when the implementation exists in another object file? Like if I declare a function inline in a.h with attribute always_inline I then use the function in b.cpp But I implement it in c.cpp I have hard time thinking this is truly possible, but maybe it is. I suspect, in b.cpp, the inlining will fail and it will resort to a regular call in object file for c.cpp correct?
