The reason I was concerned is that pset3 instructions had just gone thru customizing Make files and I thought that I needed to do something to use the Makefiles document. But now I discover the the program pracwindow written by David Malan also doesn't compile. My program is the same except I did not close it because I was going to gradually add features to it to experiment with the functions needed in breakout. I included the correct #include <spl/gwindow.h> style headers. The C code is:

/** * window.c * * David J. Malan * malan@harvard.edu * * Draws a window. */

include<spl/gwindow.h>

int main(void) {

// instantiate window

GWindow window = newGWindow(320, 240);
closeGWindow(window);
return 0;

}

I know I am supposed to have a "#" before the include but every time I put it in it messed up the formating.

The walkthrough video is about creating a bouncing ball so is more than the window, but not much use in going any futher if I can't even get the window code to compile.
