DirectFB tutorial invalid argument

Question

I don't seem to be able to launch DirectFB so that it would start without problems. I get "invalid argument" when ever I try to access functions after DFBCHECK (DirectFBCreate (&dfb)); I try to run simple example from tutorials. Code is bellow:

 #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 argx = 2;
   char *argData[] = {"self","--dfb:system=fbdev,disable-module=keyboard,disable-module=joystick,no-hardware",0};
   char **argPointer = argData;

   DFBSurfaceDescription dsc;
   DFBCHECK (DirectFBInit (&argx,&argPointer));
   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 (primary->FillRectangle (primary, 0, 0, screen_width, screen_height));
   DFBCHECK (primary->SetColor (primary, 0x80, 0x80, 0xff, 0xff));
   DFBCHECK (primary->DrawLine (primary,
                                  0, screen_height / 2,
                   screen_width - 1, screen_height / 2));

   DFBCHECK (primary->Flip (primary, NULL, 0));
   sleep (5);
   primary->Release( primary );
   dfb->Release( dfb );
   return 23;
}

As you can see I provide arguments in hard coded char*. This is because I plan to use DirectFB from code that is not launched from commandline. Code is compiled with command " gcc -I/usr/local/include/directfb dfbtest.c -o dfbtest -ldirectfb"

This generates an error:
