Are you including the same header file in multiple files ?

You may need to enclose the definitions in the header by a set of directives like so


#if !defined(SOME_CONSTANTE_OF_YOUR_CHOICE)
#define SOME_CONSTANTE_OF_YOUR_CHOICE
// Your definitions here ...
#endif


Event if those definitions are only found in one file, if the file is included in multiple other files (directly or indirectly), they will be difined multiple times.

I don't know Dev C++ nor the compiler you are using but #pragma once may also work.

I hope this helps.

Thanks, that worked ;).

*quick version*


If you want the 'long' version you can check out Wikipedia (#include guards).

This is a pretty 'beginners' error? Perhaps you should check out some more C++ books/tutorials to prevent you from making mistakes like this again. (The more you known from the language, the more optimized and clean your code will be. I speak out of experience wink.png )
We also need to be sure that these are multiple definition and not multiple declaration errors. All the header guards in the world won't prevent the linker crapping out if you declare a variable in a header that is included in more than one translation unit.
