egl gles2 "function is no-op" "Mesa: User error"

i just only try to build sample code about egl and gles2 in amd’s (1.7MB)

://developer.amd.com/wordpress/media/2012/10/gles_sdk.zip

i built it succesfully.but i get error when i run it.Notice two lines below:


(gdb) step
OnNativeWinResize (width=640, height=480) at main.cpp:108
108         ctx.nWindowWidth = width;
(gdb) step
109         ctx.nWindowHeight = height;
(gdb) step
110         glViewport(0, 0, width, height);
(gdb) step
function is no-op
111     }

and


(gdb) step
337         vs = glCreateShader(GL_VERTEX_SHADER);
(gdb) step
Mesa: User error: GL_INVALID_OPERATION in unsupported function called (unsupported extension or deprecated function?)
338         glShaderSource(vs, 1, &vsSource, NULL);

ENVIRONMENT:archlinux-kernel-3.10.10-corei5-desktop-x86_64 mesa-9.2 (gallium 0.4 on amd cedar)
please any comment.Thank you.

strongly probably mesa do not support shader compiler for the present. im not sure that wheather mesa offers glShaderBinary() replacement of shader compiler.
