Download HDF5

This download location is intended for new users of HDF5 or those looking for the most recent production version. Older versions of HDF5 can be downloaded from the Support site.

Additional considerations for Windows users and those with applications created with earlier versions of HDF5

• For Windows users:
  • The HDF Group uses an installer program to install the HDF5 libraries, header and support files on Windows. This installer is digitally signed by The HDF Group. Please be aware that the installer requires that the user have permission to install files on the target computer. Also note that the Windows binary distributions are built in Release mode with debugging symbols. Please avoid using spaces in directory path names as this can cause problems when building.
  • To use the shared libraries on Windows with Visual Studio you must specify the H5_BUILT_AS_DYNAMIC_LIB compile definition.
  • Static libraries begin with lib and shared libraries do not. For example, hdf5.lib is the shared library and libhdf5.lib is the static library.
• Applications that were created with earlier HDF5 releases may not compile with 2.0.0 by default.
  The API Compatibility Macros in HDF5 allow users to work around this issue. Users can specify a compatibility macro mapping for the version of HDF5 that an application was built with. For example, a 1.10 application can be built with 2.0.0 using either an application or library mapping as follows:
  • To compile an application built with a version of HDF5 that includes deprecated symbols (the default), specify: -DH5_USE_110_API (autotools) or –DH5_USE_110_API:BOOL=ON (CMake)
  • To build an HDF5 library with the 1.10 APIs specify --with-default-api-version=v110 (Autotools) or -DDEFAULT_API_VERSION:STRING=v110 (CMake).
  • However, users will not be able to take advantage of some of the new features in 2.0.0 if using these compatibility mappings.
• See the Migrating from HDF5 1.14 to HDF5 2.0 page for details on upgrading an application.
