Hello,
i am trying to compile gromacs-4.6.1 on a linux machine. I used already the following compile script and it worked.... export CCDIR=/usr/bin/gcc export MPICCDIR=/usr/mpi/gcc/openmpi-1.4.1/bin export CXX=mpicxx export CC=mpicc cd /home/fbafti/CODE tar -xvf gromacs-4.6.1.tar.gz cd mv gromacs-4.6.1 gromacs-4.6.1-plumed/ cd build-gromacs-4.6.1-plumed/ /home/fbafti/CODE/cmake-2.8.11.2-Linux-i386/bin/cmake /home/fbafti/CODE/gromacs-4.6.1-plumed \ -DFFTWF_LIBRARY=/home/fbafti/CODE/fftw-3.3.3/lib/libfftw3f.so \ -DFFTW3F_INCLUDE_DIR=/home/fbafti/CODE/fftw-3.3.3/include \ -DFFTW3F_LIBRARIES=/home/fbafti/CODE/fftw-3.3.3/lib/libfftw3f.a \ -DCMAKE_INSTALL_PREFIX=/home/fbafti/CODE/build-gromacs-4.6.1-plumed \ -DGMX_X11=OFF \ -DCMAKE_CXX_COMPILER=/usr/mpi/gcc/openmpi-1.4.1/bin/mpicxx \ -DCMAKE_C_COMPILER=/usr/mpi/gcc/openmpi-1.4.1/bin/mpicc \ -DGMX_MPI=ON \ -DGMX_PREFER_STATIC_LIBS=ON However I am trying it now on another machine with the same linux platform and I get the following error: CMake Warning at CMakeLists.txt:727 (message): No C SSE4.1 flag found. Consider a newer compiler, or use SSE2 for slightly lower performance -- Looking for smmintrin.h -- Looking for smmintrin.h - not found CMake Error at CMakeLists.txt:750 (message): Cannot find smmintrin.h, which is required for SSE4.1 intrinsics support. -- Configuring incomplete, errors occurred! I thought if the gcc path is already defined ... it shouldn't complain ! Can you help me figure out what causes the error?
