Help: error LNK2019: unresolved external symbol
I had the program in a single cpp file and have moved at the functions to seperate cpp's. Since doing that I received the following error when compiling the code. Any ideas on how to resolve that?

mkMainC.obj : error LNK2019: unresolved external symbol "void __cdecl mainEvent(enum PSH_Event,union PSH_EventIncoming *,void *)" (?mainEvent@@YAXW4PSH_Even

Many Thanks,

When you moved the functions to new files did you ensure you added these files to the project so they get compiled and the resultant translation units get linked into the final binary?
al lfiles -> all files of course ;)

Hi, Yes all files are under one project in VS 2005 and I have included all the header files.
Interestingly, if I remove the calls in the main() and one of the function which are listed in the error, the project complies

That's normal ;) If you removed the unresolved symbol, the linker doesn't have to look for it ... So, it doesn't throw the error either.
Can you show all your files ?

Unfortunately, I can't but I have noticed something, if I change the functions or handlers to static if resolves the issue but cause other functions to have the same error.

Why is that ?
Can you at least post the relevant parts of the code. The part of the main where the function is called, the part of the header file where the function is declared, the part of the .cpp file where the function is defined, as well as the header include at the top of the main.cpp file.

Hi Infinity, I have fixed it I removed static from all the function names and it has worked....
We could have told you that if we would have known what code you used ;) We're not clairvoyant heh.
Can you still post the code I asked for to verify that the solution is good ?

Ooops... sorry select the wrong answer... my apologies - suppose to choose
"Did you add al lfiles to one project, and then rebuild the project ?
Did you include the correct header files ?"
as I was missing my header files in the end
