Here is my program

#include<stdio.h>
#include<string.h>
struct cross_output_entry
{
char stub_descr[80];
int sort_stub_route;
double arr[20];
};
struct cross_output_type
{
union
{
char rec[8088];
struct cross_output_entry rec2;
};
};

struct cross_output_type cross;
int main()
{
int i;
FILE* fptr;
fptr=fopen("temp.text","wb");
for(i=0;i<5;i++)
{

strcpy(cross.rec2.stub_descr,"122");
cross.rec2.arr[0]=1.0;
cross.rec2.arr[1]=343.1019;
cross.rec2.arr[2]=1000.199;
cross.rec2.arr[3]=0.0;
fwrite( &cross.rec2,
sizeof(struct cross_output_type),
1,
fptr);
}
fclose(fptr);
}


The file temp.text produced in UNIX and LInux has different checksums.
Please help me to get the same check sum as i am involving myself to port application from UNIX to Linux.
