C30 PIC Compiler won't compile (MPLAB-X IDE)

Question

I am trying to compile a very simple program, I dont understand why it doesn't compile. Here is my program:

/* General includes */
#include <stdio.h>
#include <stdlib.h>
#include <libpic30.h>
#include <p33FJ128GP804.h>

#include "RunLengthAlgorithm.h"
//#include "RunLengthAlgorithm.c"

int main(void) {

    int n;
    char source[10001];
    char target[100];

    for(n = 0; n < 1000; ++n){
        source[n] = "A";
    }
    for(n = 1000; n < 2000; ++n){
        source[n] = "B";
    }
    for(n = 2000; n < 3000; ++n){
        source[n] = "C";
    }
    for(n = 3000; n < 4000; ++n){
        source[n] = "D";
    }
    for(n = 4000; n < 5000; ++n){
        source[n] = "E";
    }
    for(n = 5000; n < 6000; ++n){
        source[n] = "F";
    }
    for(n = 6000; n < 7000; ++n){
        source[n] = "G";
    }
    for(n = 7000; n < 8000; ++n){
        source[n] = "H";
    }
    for(n = 8000; n < 9000; ++n){
        source[n] = "I";
    }
    for(n = 9000; n < 10000; ++n){
        source[n] = "J";
    }
    source[10001] = '\0';

    RLEncode(&source, &target);

    while(1);
    return (EXIT_SUCCESS);

}

The .h and .c files are added to project.

#ifndef RUNLENGTHALGORITHM_H
#define RUNLENGTHALGORITHM_H

void RLEncode (char *source, char *target);

#endif

And the .c file:

#ifndef RUNLENGTHALGORITHM_C
#define RUNLENGTHALGORITHM_C
void RLEncode (char *source, char *target){
    int n, k = 0;
    for(n = 0; source[n] != '\0'; ++n){
        int length = 1;
        while(source[n+1] != '\0' && source[n] == source[n+1]){
            ++length; ++n;
        }
        target[k++] = length;
        target[k++] = source[n];
    }
    source[n] = '\0';
}

#endif

I am using MPLAB-X IDE whith C30 compiler and it gives me this error:

I don't understand why, if I put my function inside Main.c and I dont't include #include "RunLengthAlgorithm.h" it works but I cannot get it working including a file.

Answer 1

This happens when you "#include _your_func.h" your function and then manually include the file containing functions using IDE> Projects>sourcefiles> Add existing item. its sufficient to do either one of those.

Answer 2

I think the problem is related to the memory mapping. You should redefine the size of stack in .gld or .lkr files, according to the family of processor using. When you are declaring the variable source with very large memory location the stack is getting overflows.

Answer 3

Ok there is no problem whit the code. It seems to be a bug of MPLAB-X v1.10.

Solution: close MPLAB-X and open it again it will compile fine, if it doesn't work read on http://www.microchip.com/forums/m627705.aspx.
