Unresolved Extern

I am using extern in my project for variables and functions so that i can share that with my other source files in future.

How am i trying to use it?

I had made a "Header file" for Declaration of Variables and functions by the name dec.h

There is another file by the name def.c in which I had Defined those Variables and functions. def.c file includes dec.h file.

Now in my main program, when I include dec.h file only and try to build the program, compiler warns as Unresolved Extern [My function names].

Am I trying to do it the wrong way? I have read to use extern that way in the following thread How do I use extern to share variables between source files in C?

Solution

  • The above procedure was right, The problem was that I haven't included the def.c to my project files.
