compilation - Main C Program does not find header and methods -

wasn't sure how explain better in title. learning how separate code in c. have main, equivalent of arraylist class java (but converted c , basic) , header file declares struct , functions in use. using sample code out of text , using latest version of dev c++ windows 8.

every time try compile main get: in function main undefined reference "newlist" [error] id returned 1 exit status

here code:

main.c #include <stdio.h> #include "arraylist.h"  int main(int numparms, char *parms[]){      list mylist;      mylist = newlist(mylist);       printf("end");      return 0;   }  arraylist.c #include <stdio.h> #include "arraylist.h"  list newlist(list mylist){  mylist.size = 0;  return mylist; }  list add(list mylist, int value){   mylist.values[mylist.size] = value;   mylist.size++;   return mylist;   }  int get(list mylist, int position){   int entry;   entry = mylist.values[position];   return entry; }  int size(list mylist){  return mylist.size; }  list delete(list mylist, int position){      int count;    for(count =0; count<(mylist.size-1); count++){         mylist.values[count] = mylist.values[count+1];    }    mylist.size --;    return mylist; }  void print(list mylist){ int count; printf("current list contents:\n"); if (mylist.size > 0){     (count=0; count<mylist.size; count++){         printf("element %d %d\n", count, get(mylist, count));         }     printf("\n"); } else{     printf("the list empty\n\n"); }  }  arraylist.h #define max_size 100 typedef struct{  int size; int values[max_size];         }list;   list newlist(list);  list add(list, int);  int get(list, int);  int size(list);  list delete(list, int);  void print(list); 

that linker problem. compilation ok, when linker tries assemble pieces can't find newlist anywhere. guess did not compile file arraylist.c , link result project.
