#
# SYNOPSIS
#
# AX_LIB_HDF5([serial/parallel])
#
# DESCRIPTION
#
# This macro provides tests of the availability of HDF5 library.
#
# The optional macro argument should be either 'serial' or 'parallel'. The
# former only looks for serial HDF5 installations via h5cc. The latter
# only looks for parallel HDF5 installations via h5pcc. If the optional
# argument is omitted, serial installations will be preferred over
# parallel ones.
#
# The macro adds a --with-hdf5 option accepting one of three values:
#
# no - do not check for the HDF5 library.
# yes - do check for HDF5 library in standard locations.
# path - complete path to the HDF5 helper script h5cc or h5pcc.
#
# If HDF5 is successfully found, this macro calls
#
# AC_SUBST(HDF5_VERSION)
# AC_SUBST(HDF5_CC)
# AC_SUBST(HDF5_CFLAGS)
# AC_SUBST(HDF5_CPPFLAGS)
# AC_SUBST(HDF5_LDFLAGS)
# AC_SUBST(HDF5_LIBS)
# AC_SUBST(HDF5_FC)
# AC_SUBST(HDF5_FFLAGS)
# AC_SUBST(HDF5_FLIBS)
# AC_DEFINE(HAVE_HDF5)
#
# and sets with_hdf5="yes". Additionally, the macro sets
# with_hdf5_fortran="yes" if a matching Fortran wrapper script is found.
# Note that Autconf's Fortran support is not used to perform this check.
# H5CC and H5FC will contain the appropriate serial or parallel HDF5
# wrapper script locations.
#
# If HDF5 is disabled or not found, this macros sets with_hdf5="no" and
# with_hdf5_fortran="no".
#
# Your configuration script can test $with_hdf to take any further
# actions. HDF5_{C,CPP,LD}FLAGS may be used when building with C or C++.
# HDF5_F{FLAGS,LIBS} should be used when building Fortran applications.
#
# To use the macro, one would code one of the following in "configure.ac"
# before AC_OUTPUT:
#
# 1) dnl Check for HDF5 support
# AX_LIB_HDF5()
#
# 2) dnl Check for serial HDF5 support
# AX_LIB_HDF5([serial])
#
# 3) dnl Check for parallel HDF5 support
# AX_LIB_HDF5([parallel])
#
# One could test $with_hdf5 for the outcome or display it as follows
#
# echo "HDF5 support: $with_hdf5"
#
# You could also for example, override the default CC in "configure.ac" to
# enforce compilation with the compiler that HDF5 uses:
#
# AX_LIB_HDF5([parallel])
# if test "$with_hdf5" = "yes"; then
# CC="$HDF5_CC"
# else
# AC_MSG_ERROR([Unable to find HDF5, we need parallel HDF5.])
