When I am trying run program, command line for ubuntu generation error that.
I'm trying run compline program with command /build/LSB/LSB$ ./thanhtmLSBext Girl.emb.bmp
This is code of my:
File c: thanhtmLSBext.c

include <stdio.h>


include <cv.h>

include <cxcore.h>

include <cvaux.h>

include <highgui.h>

int *alloc_int_1D(int rows);
void free_int_1D(int *array);

int main(int argc, char** argv)
{
int i, j, n = 0;
IplImage* img;
FILE *fp;
int fp_size;
int wm;
 char filename = argc &gt;= 2 ? argv[1] : (char*)"Girl.emb.jpg";
 if( (img = cvLoadImage( filename, 1)) == 0 )
     return -1;

 fp = fopen( "extract.gray", "wb" );
 if( fp == NULL )
 {
      puts( "extract.grayが開けません" );
      return -1;
 }

 wm = (int *)alloc_int_1D(64*64*10);
 for(i = 0; i &lt; 64*64*10; i++){
      wm[i] = 0;
 }

 CvScalar s;
 int h=img-&gt;height;
 int w=img-&gt;width;

 for(i=0; i&lt;w;&gt;          for(j=0; j&lt;h;&gt;               s=cvGet2D(img,i,j);
           wm[n] = (int)(s.val[0])%2;
           fputc(wm[n]255,fp);
           n++;
      }
 }

 cvReleaseImage(&img);
 free_int_1D(wm);
 fclose(fp);

 return 1;

}

           n++;
      }
 }

int *alloc_int_1D(int rows) {
int *p;

p = (int *)malloc(rows * sizeof(int));
if (!p) {
ifdef DEBUG
  fprintf(stderr, "alloc_int(): malloc() failed\n");
  exit(1);

else
  return NULL;

endif

}

return p;

void free_int_1D(int *array) {
free(array);
}
I hope everybody will help me. Thanks you.
