compilation error with cv.h

Dear All,
   
  I am a newbie in OpenCV.
  I compiled a simple program as follow to test with OpenCV but it gives me so 
many errors on cv.h. The error shown after the mini program. I was using OpenCV 
4beta. Is the cv.h provided by opencv 4 beta valid to be used? Can some one 
tell me why and how to solve this problem? I really appreciate your help!
   
   
  /* usage: prog <image_name> */
#include "cv.h"
#include "highgui.h"
  int main( int argc, char** argv )
{
    IplImage* img;
    if( argc == 2 && (img = cvLoadImage( argv[1], 1)) != 0 )
    {
        cvNamedWindow( "Image view", 1 );
        cvShowImage( "Image view", img );
        cvWaitKey(0); // very important
        cvDestroyWindow( "Image view" );
        cvReleaseImage( &img );
        return 0;
    }
    return -1;
}
