Thanks for the info Carsten -
After much rebuilding & experimentation, I found this fix -
The eWebKit2 example program at :
http://ewebkit.github.io/ewebkit-doc/ewebkit2/html/
simply needs modification :
It used to say:
Ecore_Evas *win;
...
win = ecore_evas_new(NULL, 0, 0, 800, 600, NULL);
Changing the last line to:
win = ecore_evas_new("opengl_x11", 0, 0, 800, 600, NULL);
does fix the problem.
I found this out by building the /usr/os_src/efl/src/examples/evas/evas-gl.c
example .
But why doesn't it work with any of these environement variable settings :
$ ELM_ENGINE=opengl_x11 ELM_ACCEL=gl ./test
No combination of ELM_ENGINE / ELM_ACCEL settings seem to have any
effect - only explictly giving the "opengl_x11" string to ecore_evas_new works.
Shouldn't the environment variable settings work also ?
Thanks & Regards,
Jason
