[gmx-users] Re: gmx 4.6 mpi installation through openmpi?

I have a very similar problem, but compiling both Gromacs 4.6 and 4.6.1 with
cmake and MPI support (no problems with non-MPI installation). I have cmake
version 2.8.7, openmpi version 1.4.1, and I am using gcc version 4.6.3 in a
linux Ubuntu 4.6.3. I use the cmake options:
cmake -DGMX_BUILD_OWN_FFTW=ON -DGMX_MPI=ON -DGMX_BINARY_SUFFIX=_mpi
A summary of the output given by this command is:
CUDA_TOOLKIT_ROOT_DIR not found or specified
-- Could NOT find CUDA (missing: CUDA_TOOLKIT_ROOT_DIR CUDA_NVCC_EXECUTABLE
CUDA_INCLUDE_DIRS CUDA_CUDART_LIBRARY) (Required is at least version "3.2")
-- The GROMACS-managed build of FFTW 3 will configure with the following
-- Configuring done
-- Generating done
-- Build files have been written to: /home/smith/gromacs-4.6
I believe that not having CUDA installed is not a problem, as I do not plan
to run in GPU, and nowhere in the installation manual says that it is
obligatory. After running make, the simulation stops with the following
Linking C shared library libgmx_mpi.so

It looks like I lack one library somehow, but I do not know which one. I
tried to install fftw before installing gromacs, and tried with both shared
and dynamic libraries with the same result.
Can anybody help?
