Here's a simple program that works with GRX 2.2:

#include "grx22.h"

void main (void)
{
 GrSetMode(GR_320_200_graphics);

 GrLine(1,1,100,100,15);    // draw a diagonal line across half the screen
 GrPlot(160,100,1);            // plot a dot in the center of the screen

 delay(3000);                // 3 second delay to see our beautiful art
}

compile with:

gcc -o test.exe test.c -lgrx22

assuming you've named the file test.c
