[maemo-developers] [maemo-developers] Problems with Enlightenment on MAEMO / Nokia770

[From: Seb Dev]

Hello list,

I'm a MAEMO beginner and I try to run a binary on a nokia 770. I have two
problems, maybe some of you can help me :-)

1/
My program initialises an evas (enlightenment) that uses the X11 software
engine using this code :

    Window              win;
   XSetWindowAttributes attr;
   XClassHint          chint;

   disp = XOpenDisplay(NULL);
   *if* (!disp)
   {
      printf("Error: cannot open display.\n");
      exit(-1);
   }

   attr.backing_store = NotUseful;
   attr.colormap = DefaultColormap(disp, DefaultScreen(disp));
   attr.border_pixel = 0;
   attr.background_pixmap = None;
   attr.event_mask = ExposureMask | ButtonPressMask |
ButtonReleaseMask | PointerMotionMask |StructureNotifyMask
|KeyPressMask;
   attr.bit_gravity = ForgetGravity;


  win = XCreateWindow(disp, DefaultRootWindow(disp), 0, 0, win_w, win_h, 0,
      DefaultDepth(disp, DefaultScreen(disp)), InputOutput,
      DefaultVisual(disp, DefaultScreen(disp)),
      CWBackingStore | CWColormap |
      CWBackPixmap | CWBorderPixel |
      CWBitGravity | CWEventMask, &attr);

   XSetClassHint(disp, win, &chint);
#if 0
   szhints.flags = PMinSize | PMaxSize | PSize | USSize;
   szhints.min_width = szhints.max_width = win_w;
   szhints.min_height = szhints.max_height = win_h;
   XSetWMNormalHints(disp, win, &szhints);#endif

   XMapWindow(disp, win);
   XSync(disp, False);

  **
   evas_init();

   evas = evas_new();
   evas_output_method_set(evas, evas_render_method_lookup("software_x11"));
   evas_output_size_set(evas, win_w, win_h);
   evas_output_viewport_set(evas, 0, 0, win_w, win_h);

  {
      Evas_Engine_Info_Software_X11 *einfo;

      einfo = (Evas_Engine_Info_Software_X11 *) evas_engine_info_get(evas);**
      einfo->info.display = disp;
      einfo->info.visual = DefaultVisual(disp, DefaultScreen(disp));
      einfo->info.colormap = DefaultColormap(disp, DefaultScreen(disp));
      einfo->info.drawable = win;
      einfo->info.depth = DefaultDepth(disp, DefaultScreen(disp));
      einfo->info.rotation = 0;
      einfo->info.debug = 0;
      evas_engine_info_set(evas, (Evas_Engine_Info *) einfo);
   }



This program works well in PC environment and in scratchbox MAEMO
environment, but I have a segmentation fault when I launch it on Nokia 770
on line
einfo->info.display = display;

I don't understand why, maybe because of the X11 software engine ?

(NB) Before launching the program, I have to make a
export DISPLAY=:0

2/  Second problem :

    imlib_context_set_image(buffer);
   imlib_save_image("file.jpg");

   evas_object_del(tmp);
   tmp = evas_object_image_add(evas);
   evas_image_cache_reload (evas);**
   evas_object_image_file_set(tmp, "file.jpg", NULL);


The function imlib_save_image works well in PC environment and in scratchbox
MAEMO environment, but on the Nokia770, no file.jpg is created and I don't
have any error code in return.

That's why evas_object_image_file_set return a segmentation fault after.

Any idea to explain why imlib_save_image("file.jpg") creates no file.jpg ? I
execute the program in /home/username on nokia770.

Thanks a lot in advance for your response,

Seb
