All, I'm attempting to build gromacs 4.6.2 with a bit of everything: CUDA support, MPI, Intel compilers, etc. using the new cmake system. I've set CC and CXX to specify the Intel compilers:
[root@login002 build]# echo $CC icc [root@login002 build]# echo $CXX icc and sourced the setup script for good measure: /export/intel/composer_xe_2013.1.117/bin/compilervars.sh intel64 During cmake, everything appears to be happy: [root@login002 build]# /export/cmake-2.8.1/bin/cmake -DGMX_GPU=ON DCUDA_TOOLKIT_ROOT_DIR=/export/cuda-5.0 -DGMX_BUILD_OWN_FFTW=ON -DGMX_FFT_LIBRARY=mkl -DGMX_MPI=ON -DCMAKE_INSTALL_PREFIX=/export/gromacs-4.6.2 .. | tee cmake.out ... -- The C compiler identification is Intel -- Check for working C compiler: /export/intel/composer_xe_2013.1.117/bin/intel64/icc -- Check for working C compiler: /export/intel/composer_xe_2013.1.117/bin/intel64/icc -- works ... -- Looking for NVIDIA GPUs present in the system -- Could not detect NVIDIA GPUs -- Found CUDA: /usr/local/cuda ... -- MPI is not compatible with thread-MPI.

I tried tricking it to use something more recent: alias /usr/bin/gcc44 gcc alias g++=/usr/bin/g++44 But I still see the path pointing to 4.1.2. Any suggestions on things to try?
