Building A Cactus Configuration with IOHDF5Util

The Cactus distribution does not contain the HDF5 header files and library which is used by thorn IOHDF5Util. So you need to configure it as an external software package via:

  make <configuration>-config HDF5=yes
                             [HDF5_DIR=<path to HDF5 package>]

The configuration script will look in some default places for an installed HDF5 package. If nothing is found this way you can explicitly specify it with the HDF5_DIR configure variable.
