Did you re-add it to both main.c and kbhit.c?
Which ones did you define MAIN in?

The error in this case implies MAIN should be defined in kbhit.c.

It is added in kbhit.c and delta.h, which is included in main.c

main() is defined in main.c

really? Which part of the error implies that? How could that have happened?

Thanks!

I think I got it. There seemed to be some issue with having a function named kbhit() inside the file named kbhit.c

Anyways, now it's compiling. Thanks a lot for your help!

--- Code: ---#ifdef MAIN
#define EXTERN           // the Main module defines objects
#else
#define EXTERN extern    // others modules see objects as externs
#endif

--- End code ---

The above code means normally define EXTERN as extern; but, in the Main module define it as nothing.
Sometimes the Main modules is the code holding the main() and sometimes it is the "c" file that goes with header.

I am guessing that since you are having issues with kbhit.c errors; that in this case MAIN needs to be defined there. But, it is just a guess!

Where are you defining MAIN?

Could be an Compiler or linker bug.
