I am trying to compile Gromacs-5.0.7 with command:

CC=mpicc CXX=mpicxx F77=mpif90 FC=mpif90 LDF90=mpif90 
-DCMAKE_INSTALL_PREFIX=/home/albert/install/gromacs/5.0.7 -DGMX_MPI=ON 

but it failed with messages:

CMake Error at cmake/gmxTestSimd.cmake:244 (message):
   Cannot find AVX2 compiler flag.  Use a newer compiler, or choose AVX SIMD
Call Stack (most recent call first):
   CMakeLists.txt:729 (gmx_test_simd)

I am using gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5). Cmake 
version. 3.3.2

Does anybody have any idea?

Thx a lot
