Dear All,

May be i could have write the same earlier, but still i am not clear, deep 
apolozise for fillup your inbox.

    I downloaded Mesa 7.8.2 and configured with
./configure --prefix=/usr --enable-gles2 --enable-egl 
--with-egl-platforms=x11,drm --enable-gallium-egl=i915 
--with-dri-drivers=i915,swrast --disable-glw

I belive this configuration will built hardware pipe line driver for i915 GPU

after built and install. i can see libraries in /usr/lib/ and /usr/lib/egl/

i have simple gles test application runs pretty good with software acceleration 
in different machine. when i try to run the same application by loading the 
newly built mesa librires i am getting below error.

libEGL warning: Could not open driver /usr/lib/egl/egl_glx 
(/usr/lib/egl/egl_glx: cannot open shared object file: No such file or 
libEGL warning: The driver can be overridden by setting EGL_DRIVER
Error returned by eglCreateWindowSurface - error = 0x3005

if i do set EGL_DRIVER=/usr/lib/egl/egl_dri2.so i am getting the same error.

My question is first is.
1) is the configuration options what i am enabling is right?to get the hardware 
GPU enabled GLES rendering.
2) How can i resolve above errors while running the application?
3) after appliaction start runs successfully how can i ensure that it goes 
through hardware pipe line only?

could anyone please give me hint to solve this issue.

eagerly waiting for reply.

Many thanks in advance.
