CCS/MSP430G2553: Warning about implicity-declared function when using libraries

Hi There,

To make my code more readable/portable, I've moved many functions to separate library files. However, now when I compile my main project, I get warning about

#225-D: function "<function_name>" declared implicitly

Does anyone have a nice remedy for this? I'm hoping to avoid having to declare the functions in my main.c file.

THANKS!

For each function you moved to "mumble.c", add a declaration to "mumble.h".

Just copy each function prototype, prepend "extern" and put a ";" at the end. It's pretty quick.

.... then don't forget that #include "mumble.h"

thanks and have fun
