I thought I listed the entire file but will list it again.

I need more code????

test.c

  typedef struct
  {
	/* # of entries in data */
	int entries;
	/* entry size and count */
	int size;
	int cnt;
	/* data; array of bytes, one row after another. */
	char *data;
  }
  gFast;

/* Location functions take these. */
  typedef gFast * gFastPtr;

char TestDATA[20];

gFast gFastTestRep = {
	2,
	2,
	10,
	(char *)TestDATA,
};

/*
   this is all the data
   the file should be 32 bytes in length
  20 bytes of data and 12 bytes for header
*/

char TestDATA[] = {
	
	/* Entry 000 */
	1,2,3,4,5,6,7,8,9,10,

	/* Entry 001 */
	11,12,13,14,15,16,17,18,19,20,
};

gFastPtr gFastTest = &gFastTestRep;

I've tried compiling it with:

gcc -c -static -o test.out test.c

this is the contents of the file after compiling with the above command.

the valid data starts at '000000f4' and ends at '00000118'.

If I need to do something more to get it in the format that I need  
I'b be more than happy to follow any instruction you provide.
