Building Panda3D with OpenGL ES using Cygwin and MSVC9. Log

Compiling or Editing the Panda Source

The error is thrown by this code:

  int attrib_list[] = {
#ifdef OPENGLES_1
    EGL_RENDERABLE_TYPE, EGL_OPENGL_ES_BIT,
#endif
#ifdef OPENGLES_2
    EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT,
#endif
    EGL_SURFACE_TYPE, EGL_DONT_CARE,
    EGL_NONE
  };

  int num_configs = 0;
  EGLConfig configs[32];
  if (!eglChooseConfig(_egl_display, attrib_list, configs, 32, &num_configs) || num_configs <= 0) {
    egldisplay_cat.error() << "eglChooseConfig failed: "
      << get_egl_error_string(eglGetError()) << "\n";
    return;
  }

Because eglGetError() apparently returns EGL_SUCCESS, I can assume that it just returns no available configs.

Are you sure that EGL is supposed to work? The code asks for a GLES2 renderable, does your device really support GLES2? Otherwise you should try the pandagles renderer.
