title: trying to do GUI using C
body: <p>I'm trying to write code for little GUI in C.
  my code is :</p>
  
  <pre><code>#include &lt;stdgui.h&gt;
  
  CALLBACK(draw_hello, evt, param)
  {
  int ascent, descent;
  FONT fnt;
  
  fnt = get_appfont();
  get_font_info(fnt, &amp;ascent, &amp;descent, NULL);
  plot_str(evt-&gt;graphic, 5, 5+ascent+descent, "Hello World", fnt);
  
  return 0;
  }
  
  int main(int args, char *arg[])
  {
  int rv;
  
  start_gui("Hello", args, arg, 0,
      DEF_CB, "draw_hello", draw_hello, DONE);
  
  create_window("Hello", 0, 0, 200, 100, 0,
      SET_PROP, "ON_REDRAW", 1, "draw_hello", DONE);
  
  run_event_loop(&amp;rv);
  
  return rv;
  </code></pre>
  
  <p>}</p>
  
  <p>but its showing error :
  gui.c:1:20: fatal error: stdgui.h: No such file or directory...
  what to do..?</p>
  
  <p>Also i tried GTK first but its very difficult to install.
  I'm tired of doing that and needed very small gui so shifted to the stdgui.
  Any help in that issue will be appreciated.</p>
