Hi Yukun,

In future, please only target email associated with GROMACS development to
the gmx-developers mailing list. gmx-users is for usage questions, such as
installation issues. I am replying to this email to both lists.

If you've correctly installed and used icc 11.1, then I think you should
not have this problem. Try a full-qualified path to icc - I don't know if
your use of CMAKE_PREFIX_PATH is sufficient there - and IIRC if you have
sourced the environment script that comes with Intel's compilers then you
should not need to touch CMAKE_PREFIX_PATH for the compiler. The compiler
diagnosis is at the very top of the cmake output, so please look there for

Hi all:
   I am trying to install GMX 4.6 beta2 on a highly paralleled server.
      with cmake  version 2.8.4
           MPI        openmpi-144 compiled with intel 11.1 compiler
           fftw         3.3.2
           compiler  intel 11.1 gcc 4.1.2
           CPU      Intel(R) Xeon(R)  E5450 with 8cores in one node, with
infinited band node communication.
       with the compling commend:

 # CMAKE_PREFIX_PATH=/home/software/openmpi-144-intel-11-1:/home/dw11-sg007/dying/fftw3
CC=icc  /home/software/cmake-2.8.4/bin/cmake ..
        then I got such a error :
               CMake Warning at CMakeLists.txt:733 (message):
               No C SSE4.1 flag found.  Consider a newer compiler, or
disable SSE4.1 for slightly lower performance.
               CMake Error at CMakeLists.txt:756 (message):
               Cannot find smmintrin.h, which is required for SSE4.1
intrinsics support.
  Is there anybody knowing how to handle such a problem?  Thank you very
much !
