Error Error while executing Directfb program on ubuntu

Hi ,
I am getting error while executing Directfb program on ubuntu ,,
my program is :

#include <stdio.h>
#include <unistd.h>



#include <directfb.h>



static IDirectFB *dfb = NULL;
static IDirectFBSurface *primary = NULL;
static int screen_width = 0;
static int screen_height = 0;
#define DFBCHECK(x...)
{
DFBResult err = x;

if (err != DFB_OK)
{
fprintf( stderr, "%s <%d>:\n\t", __FILE__, __LINE__ );
DirectFBErrorFatal( #x, err );
}
}
int main (int argc, char **argv)
{
int i;



DFBSurfaceDescription dsc;

IDirectFBImageProvider *provider;



DFBCHECK (DirectFBInit (&argc, &argv));
DFBCHECK (DirectFBCreate (&dfb));
DFBCHECK (dfb->SetCooperativeLevel (dfb, DFSCL_FULLSCREEN));
dsc.flags = DSDESC_CAPS;
dsc.caps = DSCAPS_PRIMARY | DSCAPS_FLIPPING;
DFBCHECK (dfb->CreateSurface( dfb, &dsc, &primary ));
DFBCHECK (primary->GetSize (primary, &screen_width, &screen_height));
DFBCHECK (dfb->CreateImageProvider (dfb, DATADIR"/dfblogo.png", &provider));

DFBCHECK (provider->GetSurfaceDescription (provider, &dsc));

DFBCHECK (dfb->CreateSurface( dfb, &dsc, &logo ));

DFBCHECK (provider->RenderTo (provider, logo, NULL));
provider->Release (provider);
for (i = -dsc.width; i < screen_width; i++)
{
DFBCHECK (primary->FillRectangle (primary, 0, 0, screen_width, screen_height));
DFBCHECK (primary->Blit (primary, logo, NULL, i, (screen_height - dsc.height) / 2));

DFBCHECK (primary->Flip (primary, NULL, DSFLIP_WAITFORSYNC));
}
logo->Release (logo);

primary->Release (primary);
dfb->Release (dfb);

return 23;
