Hi list,
I am a newbie who study efl programming recently. I try to write my first
program but meet problem always return NULL for creating canvas. I have
googled someone met that too but no clear answer.
I can get supported engines by ecore_evas_engines_get(), are software_x11,
xrender_x11, opengl_x11, fb, and buffer.
My platform is Ubuntu 9.10 and I think I installed all necessary libraries
since I can build it successfully by command.
gcc `pkg-config --libs --cflags evas ecore ecore-evas` ecore_test.c -o
ecore_test
My code is following.
...
22 if ( !ecore_init()) return EXIT_FAILURE;
23 if ( !ecore_evas_init()) return EXIT_FAILURE;
24
25 if (NULL == (eina_list = ecore_evas_engines_get()))
26 return EXIT_FAILURE;
27
28 EINA_LIST_FOREACH(eina_list, l, data)
29 if(data) printf("data %s\n", data);
30 ecore_evas_engines_free(eina_list);
31
32 ecore_evas = ecore_evas_software_x11_new(NULL, 0, 0, 0, W, H);
33 if (!ecore_evas)
34 ecore_evas = ecore_evas_gl_x11_new(NULL, 0, 0, 0, W, H);
35 if (!ecore_evas)
36 ecore_evas = ecore_evas_fb_new(NULL, 0, W, H);
37 if (!ecore_evas)
38 ecore_evas = ecore_evas_xrender_x11_new(NULL, 0, 0, 0,
W, H);
39 if (!ecore_evas){
40 printf("ERROR: Cannot create canvas\n");
41 return EXIT_FAILURE;
42 }
...
Thanks,
Shuduo
