Can't compile if functions are in a separate file

[yawn]

Hello,

The compiler that comes with the Arduino IDE doesn't seem to like it when you have your functions or classes in separate files. Does it work ok with anothe IDE? How do you do to avoid this problem?

That is because you need to pre-declare the function also in the file you use them.
So lets say you have otherfile.ino:

Code:

int add(int x, int y){
    return x+y;
}


Then add to the top of you main.ino:

Code:

int add(int x, int y);

Thanks! Works fine. Classes won't though. Any other way than creating a library? (saving this link here for future reference https://www.arduino.cc/en/Hacking/LibraryTutorial)

You can put the class layout thing in your main.ino file, i think, and then have myclass::myfunc(int blahblahblah); in that other ino file

Should've tried that, thanks!

You might want to start using header file syntax and then #include "myclass.h"
