Rather than fidget with GLES version, though, it's best to just use the same preprocessor pattern that you used in have_tex_storage_support(), which should work regardless of the GLES version. > + return piglit_is_extension_supported("GL_EXT_texture_cube_map_array"); > +#elif defined (PIGLIT_USE_OPENGL) > + return piglit_get_gl_version() >= 40 || > + piglit_is_extension_supported("GL_ARB_texture_cube_map_array"); > +#endif > + return false; > +} > + > + > +enum piglit_result > +piglit_display(void) > +{ > + unsigned i; > + bool have_cube_map_ext = have_cube_map_array_support(); > + bool have_tex_stor_ext = have_tex_storage_support(); > + bool have_mipmap = > piglit_is_extension_supported("GL_ARB_framebuffer_object"); Please rename have_mipmap to have_generate_mipmap, have_gen_mipmap, or something similar.
