Intel HLS example reports

Dear Anand

thanks for the reply..... I am trying to compile a very simple C++ algorithm. The din_t I am taking as ac_int<16> and d_out I am taking as ap_int<48>....The length of vector as N=10... I have compiled it in another HLS tool.... I will be grateful if you can check if I am following the right difrection towards synthesis in Intel HLS..... In my code there is a component and below i have the test bench under int main(void)....This test bench works in other HLS tool.... I am having problem in Intel HLS with this...Can you figure out what is wrong in it ? Will be really thankful...

# include "HLS/hls.h"

# include <stdio.h>

# include "HLS/ac_int.h"

# include "HLS/ac_fixed.h"

# include "HLS/math.h"

for(i=0; i<N; i++)

{

# pragma HLS PIPELINE II=1

a_reg = a;

b_reg = b;

sub = a_reg - b_reg;

sub2 = sub*sub;

acc += sub2;

}

*dout = acc;

//check results
