Building HDF5

For a smooth building step ensure that the following environment variables are set (if the libraries are installed globally on the system):

  • HDF5: HDF5_DIR (for CMake-build HDF5) or HDF5_ROOT (for HDF5 build with the configure script) or globally installed HDF5

The following libraries are installed locally within PICLas and build automatically (in case the PICLas needs in case they are not found on the system):

  • [HDF5][hdf5]: Library for efficient I/O on large scale systems (always needed)

    Manual HDF5-Installation

  • Download HDF5 from www.support.hdfgroup.org

      tar xvf hdf5-version.tar.gz

  • Create Build folder

      cd hdf-version && mkdir -p build

  • Configure and make HDF5

       cmake -DBUILD_TESTING=OFF -DHDF5_BUILD_FORTRAN=ON -DHDF5_BUILD_CPP_LIB=OFF -DHDF5_BUILD_EXAMPLES=OFF -DHDF5_ENABLE_PARALLEL=ON -DHDF5_BUILD_HL_LIB=ON -DHDF5_BUILD_TOOLS=ON -DHDF5_ENABLE_F2003=ON -DBUILD_SHARED_LIBS=OFF -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/opt/hdf5/1.X.X ..

  • Make make && make install

  • Setting variables

       installed with config script: export HDF5_DIR = /opt/hdf5/1.X.X/
   installed with cmake: export HDF5_DIR = /opt/hdf5/1.X.X/shared/cmake/XXX

  • CMAKE>3.9.+

    CMake uses a new findPackage, hence HDF5_ROOT is used, e.g.

       export HDF5_ROOT=/opt/hdf5/1.10.0-patch1/mpi/
