  1. Create a working directory.

  2. Uncompress the HDF4 CMake source code file into the working directory. It will contain a CMake-hdf-N directory (where N is the release version).

  3. From the command line, go into the CMake-hdf-N directory, which contains:

     

    build*.sh (.bat)

    Build Script(s)

    CTestScript.cmake

    ctest Command

    hdf-N/

    HDF4 Source Code

    HDF4config.cmake

    Configuration file

    HDF4options.cmake

    User modifiable options

    JPEG8d.tar.gz

    External library for JPEG Compression

    SZip.tar.gz

    External library for SZIP Compression

    ZLib.tar.gz

    External library for ZLIB Compression

  4. By default HDF4 will be built:
      • Without Fortran
      • With SZIP compression enabled
      • With ZLIB compression enabled
      • With static libraries enabled

    Users can change the options that HDF4 is built with by adding options to the build command (see the batch files/test script below) or by modifying the HDF4options.cmake file. The HDF4options.cmake file will override any options set in the configuration file. For more information see the How to Change HDF4 CMake Build Options page.

    REQUIRED: Visual Studio Express users must change the build options to turn off packaging or the build will fail.
     

  5. Execute the batch file or shell script containing the ctest command for your platform.  (See Troubleshooting if you do not see your platform).

    Example build files are shown below:

    PlatformBatch File / Shell Scriptctest command
    Windows 64-bit VS 2015build-VS2015-64.batctest -S HDF4config.cmake,BUILD_GENERATOR=VS201564 -C Release -V -O hdf4.log
    Windows 32-bit VS 2015build-VS2015-32.batctest -S HDF4config.cmake,BUILD_GENERATOR=VS2015 -C Release -V -O hdf4.log
    Unixbuild-unix.shctest -S HDF4config.cmake,BUILD_GENERATOR=Unix -C Release -V -O hdf4.log

    Where the ctest command is using these options:

    1. The -S option uses the script version of ctest.
    2. The -C option specifies the build configuration which matches CTEST_BUILD_CONFIGURATION in the configuration file.
    3. The -V option indicates verbose. -VV option indicates more verbose.
    4. The -O option saves the output to a log file, hdf4.log.

  6. Locate the built binary.

    The built binary will be placed in the build directory and will have the format:
    hdf-4.2.N-<platform.<zip or tar.gz>

    On Windows, a .msi or .exe file will also be created, depending on the installer. On Unix, an additional .sh file will be created.

    If the built binary is not there, then see Troubleshooting for help.
     

  7. Check what is included with your built binaries 
     
    You will find the libhdf4.settings file in the build directory. It contains information on how the binaries were built.
