Instructions for the Installation of HDF5 Software
==================================================
This file provides instructions for installing the HDF5 software.
For help with installing, questions can be posted to the HDF Forum or sent to the HDF Helpdesk:

*****************************************************************************
1. Obtaining HDF5
The latest supported public releases of HDF5 are available on
https://github.com/HDFGroup/hdf5.
2. Third-party Software Requirements
2.1. Zlib
The HDF5 library includes a predefined compression filter that
uses the "deflate" method for chunked datasets. If zlib-1.1.2 or
later is found, HDF5 will use it. Otherwise, HDF5's predefined
compression method will degenerate to a no-op; the compression
filter will succeed but the data will not be compressed.
2.2. Szip (optional)
The HDF5 library includes a predefined compression filter that
uses the extended-Rice lossless compression algorithm for chunked
datasets.
Building instructions are available with the Szip source code.
The HDF Group does not distribute separate Szip precompiled libraries,
but the HDF5 pre-built binaries provided on The HDF Group download page
include the Szip library with the encoder enabled. These can be found
here:
https://www.hdfgroup.org/downloads/hdf5/
Please notice that if HDF5 configure cannot find a valid Szip library,
configure will not fail; in this case, the compression filter will
not be available to the applications.
To check if Szip compression was successfully configured in,
check the "I/O filters (external):" line in the configure output,
summary section, printed to the standard output.
2.3. MPI and MPI-IO
The parallel version of the library is built upon the foundation
provided by MPI and MPI-IO. If these libraries are not available
when HDF5 is configured, only a serial version of HDF5 can be built.
3. HDF5 Source Code and Precompiled Binaries
The HDF Group provides source code and pre-compiled binaries from the
HDF5 github releases page:
https://github.com/HDFGroup/hdf5/releases
4. Build and Install HDF5 on Unix and Mac OSX Platforms with autotools
see the release_docs/INSTALL_Autotools.txt file.
5. Build and Install HDF5 Libraries and tools with CMake
see the release_docs/INSTALL_CMake.txt file.
