[E-devel] Problems with Enlightenment on MAEMO / Nokia770

[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 Dev
