Errors in my code!! was no errors in other compilers,

Postby NabeelLass » Mon Mar 14, 2016 6:36 pm

Hello,
I wrote a program for decompressing the image using IDCT code. It working fine with other C compiler programs but I got 4 errors when I start using XMOS studio.
errors are attached.
Is there any one can help?

Code: Select all

#include <stdio.h>
#include "math.h"
#include <xs1.h>

int i,j,k,l,n,p,t,f;
int r=0,c=0;
int ROWS=8;
int COLS=8;

void mul_func(double idctmtrx[ROWS][COLS], double array[ROWS][COLS],double multip1 [ROWS][COLS])
{
    int t,n,f;
    double multip[8][8]={};
    // multip1=multip;
    for (t=0;t<ROWS;t++)
for (n=0;n<COLS;n++)
for (f=0;f<COLS;f++)
    multip[n][t]+=idctmtrx[t][f]*array[f][n];

    for (t=0;t<ROWS;t++)
for (n=0;n<COLS;n++)
for (f=0;f<COLS;f++)
    multip1[n][t]+=idctmtrx[t][f]*multip[f][n];


}


int main() {
    double uncomp_mtrx[64][64]={0}; // decompress image to 64X64 pixel
    double multip1[8][8]={};
    double blk8[8][8]={};
    int blk_size1=0,blk_size2=0;
    int z,y;
    // IDCT block matrix
    double idctmtrx[8][8]={
    {0.3536, 0.4904, 0.4619,  0.4157, 0.3536,  0.2778, 0.1913, 0.0975},

This one's straight forward:

change

Code: Select all

int ROWS=8;
int COLS=8;
to

Code: Select all

#define ROWS 8
#define COLS 8
You array sizes in functions must be constants, they can't be 'int'.

Put that code in a C file, these restrictions only apply to XC code

Great!!
Only replacing

Code: Select all

int ROWS=8;
int COLS=8;
with

Code: Select all

#define ROWS 8
#define COLS 8
is solved the problem.
Thank you to you all
