Hi All,
Thanks for your reply,
I tried as u said by giving the GALLIUM_DRIVER as softpipe and now glxgears
was working fine.As u said the problem is in gallium driver .
Now again i tried by setting GALLIUM_DRIVER=llvmpipe ,and i try to run
"glxgears" from opengles1 sample but its getting crashed inside the gallium
llvmpipe driver.
I just given some prints in the "lp_state_vertex.c" which resides inside
"mesa-master/src/gallium/drivers/llvmpipe"
Iam not sure why its crashing in the llvm pipe.
once again iam informing that my intension is to run any of the
opengl/opengles application with gallium mesa3d with llvm support and check
the
performance in linux (fedora 11).
*NOTE : *LLVM libraries used to compile gallium mesa 3d
: clang_llvm-2.7-i686-linux
*Mesa Version : Mesa 7.10.0*
$ ./configure --enable-debug --enable-gles1 --enable-gles2
--enable-gallium-svga --enable-gallium-i915 --enable-gallium-i965
--enable-gallium-llvm --disable-glut --with-dri-drivers=
--disable-gallium-radeon --enable-gles-overlay
--with-state-trackers=egl,vega
*These are my export variables*.:

It seems the function "draw_llvm_shader_elts() is getting crashed.
can any one help me to fix out this issue.
Thanks
