Hi All,
Thanks in advance for your help. I am trying to add the source code from an existing c program to my c++ project developed in Xcode. I suspect I may be over simplifying, but I was hoping I could add the source files to my project, rename the main function in the c program and call the new function from a c++ class in my existing project. The c files compile fine, but when the program tries to link I get "symbol not found". I took a look at http://www.codeguru.com/forum/showth...source+program But adding the extern "C" to the headers doesn't help. I created a simple .h and .c file to show what I am trying to do:

temptry.h looks like:

#ifndef MY_H_
#define MY_H_

#include <stdio.h>

int my_main (int, char*);

#endif

and temptry.c look like:

#include "temptry.h"

int my_main(int argc, char *argv[]) {

printf("here\n");
}



I call my_main from my c++ class which includes "temptry.h"

the function call looks like:

my_main(numArgs, clearcutParameters);

Thanks again for any and all suggestions!
