I am a first time user of grx22(tho a long-time user of main frames
for computations) & am having trouble getting gcc to recognise
_dpmi_regs   &
dos_ds                                                         in my code,
tho I have included the  files <g032.h>, <dpmi.h>.  Can you help me? The
 necessary changes to the DJGPP.ENV file have 
been made, but I could not successfully run the test programs that
come with grx22, since my PC (that has a Cirrus Logic GD5458, 
chip) does not have a graphics driver(as found from modetest).
Can you tell me where I can download one from?

I am yet to find a low-brow intro. to graphics, for someone who can afford to
 be only moderately interested in the details.

Thanks ,

Ok the code compiles, but it does nothing.

here is the complete code:

#include <allegro.h>

int main(void)
{
  MIDI *MissionHandler; /* need to keep track of resources */

  allegro_init(); /* must initialize Allegro first */
  install_timer();

  MissionHandler = load_midi("mib.mid"); /*delete above line, use */
  play_midi(MissionHandler,TRUE); /* Delete above line, use this */

}

I do have the file in the same directory as the compiled file

Mike.
