Release of HDF 4.2.7
The release of HDF 4.2.7 is now available. It can be obtained from the HDF Downloads page:
https://support.hdfgroup.org/downloads/index.html#hdf4
For the HDF 4.2.7 documentation, see:
https://support.hdfgroup.org/release4/doc.html
Important new features and changes in this release include:
-
VSgetexternalfile and SDgetexternalfile were superseded by VSgetexternalinfo and SDgetexternalinfo because their prototypes were missing the parameter "length" for the external data length.
-
This release adds support for building HDF (HDF4) using CMake 2.8.6 (see http://www.cmake.org/).
This is the first step in supporting CMake in HDF4. Initial work targets building on Windows only, but CMake can be used on other platforms, as well. Please refer to the ./release_notes/CMake.txt file in the source code for more details on building HDF4 with CMake.
-
The Fortran wrappers vfgvgroups and vsfgvdatas have been added for Vgetvgroups and VSgetvdatas, respectively.
-
Support was added for IBM XL Fortran for Linux 64-bit and Linux PowerPC 64 Version 13.1.
-
Numerous bug fixes were made.
Please be sure to see the HDF 4.2.7 Release Notes for complete details on what has changed in this release:

Release of H4toH5 Conversion Library and Tools Version 2.2.1
Version 2.2.1 of the H4toH5 Conversion Library and Tools is now available. This release has been tested with HDF5-1.8.8 and HDF 4.2.7. See the conversion library and tools web page for complete details regarding this release:
https://support.hdfgroup.org/h4toh5/
The software can be obtained from the conversion library and tools web page, as well as the HDF Downloads page:
https://support.hdfgroup.org/downloads/index.html#h4h5
The conversion software consists of command-line utilities (h4toh5, h5toh4) as well as a conversion library for converting individual HDF4 objects to HDF5 objects.
Important new features and changes in this release include:
-
The source code has been changed to use the HDF5 v1.8 API. This means when using HDF5 v1.8 to build the library and tools, one no longer needs to and should not use CPPFLAGS=-DH5_USE_16_API.
-
The -nc4 and -nc4fakedim options for converting HDF-EOS2 to netCDF-4 are not supported in version 2.2.1, but may be supported again in a future release.
-
Support was added for Linux 2.6 PowerPC 64, using GCC v4.4.6.
Changes to Windows Support in HDF4 and H4toH5 Conversion Library and Tools
The next release of both the HDF4 library and H4toH5 conversion software will include changes to how Windows is supported.
CMake will be used exclusively to build the Windows libraries and executables. The windows/ directory will no longer be included in the source code, which means the VS 2008 project files will no longer be provided.
CMake is a cross-platform build system generator. Projects specify their build process with platform-independent CMake listfiles. These are included in each directory of a source tree with the name CMakeLists.txt. Users build a project by using CMake to generate a build system for a native tool on their platform.
More information on CMake can be found at the KitWare site:
http://www.cmake.org/
We are also moving our Windows reference platforms to Windows 7 using Visual Studio 2010 and Intel Fortran 12.
