I am trying to convert nano-X.h to a pas file but I get some errors. This is 2 of them.
I cannot se what the problem is, can anyone give me a hint.

h2pas is not perfect, some things it doesn't understand, and other "C" things simply don't make sense in Pascal.

So you will probably end up translating a lot by hand.

My guess, the two problems you posted would look
something like this:

(**************************)

const GR_ERROR_STRINGS: array[0..17] of pchar = (
' ',
'Bad window id: %d'#10,
'Bad graphics context: %d'#10,
'Bad cursor size'#10,
'Out of server memory'#10,
'Bad window size: %d'#10,
'Keyboard error'#10,
'Mouse error'#10,
'Input only window: %d'#10,
'Illegal on root window: %d'#10,
'Clipping overflow'#10,
'Screen error'#10,
'Unmapped focus window: %d'#10,
'Bad drawing mode gc: %d'#10,
'Bad line attribute gc: %d'#10,
'Bad fill mode gc: %d'#10,
'Bad region id: %d'#10,
nil
);

procedure GrSetWindowBackgroundColor(wid:GR_WINDOW_ID; color:GR_COLOR);
var
  props: GR_WM_PROPERTIES;
begin
  props.flags := GR_WM_FLAGS_BACKGROUND;
  props.background := color;
  GrSetWMProperties(wid, @props);
end;

You might also try pre-processing the headers
with cpp -nostdinc (or gcc -E)
