Hi All,
I've discovered a new problem when using CMake. To recap, the system in
question is a PowerPC cluster running Yellowdog Linux with OpenMPI-1.4.2 and
gcc-4.2.2, linking against FFTW 3.0.1.
I gave the following commands to build mdrun with CMake:
cmake ../gromacs-4.5.1
-DFFTW3F_LIBRARIES=/home/rdiv1001/fftw-3.0.1-linux/lib/libfftw3f.so
-DFFTW3F_INCLUDE_DIR=/home/rdiv1001/fftw-3.0.1-linux/include/
-DCMAKE_INSTALL_PREFIX=/home/rdiv1001/gromacs-4.5_cmake-linux
-DGMX_BINARY_SUFFIX=_4.5_cmake_mpi –DGMX_THREADS=OFF –DGMX_X11=OFF -DGMX_MPI=ON
-DMPI_COMPILER=/home/rdiv1001/compilers/openmpi-1.4.2/bin/mpicxx
-DMPI_INCLUDE_PATH=/home/rdiv1001/compilers/openmpi-1.4.2/include
make mdrun
make install-mdrun
When attempting to invoke the resulting "mdrun_4.5.1_cmake_mpi" executable, I
get the following error:
/home/rdiv1001/gromacs-4.5.1_cmake-linux/bin/mdrun_4.5.1_cmake_mpi: error while
loading shared libraries: libgmxpreprocess_mpi.so.6: cannot open shared object
file: No such file or directory
Adding -DBUILD_SHARED_LIBS=OFF solves the problem. Since (by default) Gromacs
builds shared libraries, I thought this little problem should be reported, even
though I can work around it. The cmake and subsequent make steps reported no
problems whatsoever beyond a couple of minor compiler warnings, so I assumed
that everything had gone well.
