duplicate symbol error in C -

-

i have following code layout

header.h

#ifndef _header_h #define _header_h void empty(float *array, int l) {     int i;     (i=1 ; i<=l ; i++)     {         array[i]=0;     }  }  #endif

and 2 files (lets call them file1.c , file2.c)

#include "header.h"  void function/*1 or 2*/(){       ....      empty(a,b);      .... }

so compiling works fine linker command fails compiler says there duplicate function definition. how can avoid still using header file? working fine when define function in header , create .c file containing full function. thought declaring in header way go.

i thought declaring in header way go.

yes, is. declaring in header fine. not define in header, though. (unless it's static inline, don't want these days.)
