The basics steps to install HDFView are:


  • Build HDF5 (and HDF4 if needed) with Java enabled with shared libraries.
  • Set JAVA_HOME and ANT_HOME to the top directory for the Java and Ant installations.
  • Set the HDFLIBS and HDF5LIBS environment variables to point to the install location of HDF4 and HDF5. (If you do not want to include the HDF4 library just set HDFLIBS to the path for HDF5.)
  • Run ant run.
  • Run ant package.
  • The built binary will be in the build/dist directory of the HDFView source.


  • Build HDF4 and HDF5 with Java enabled with shared libraries (with CMake). All you should have to do is edit HDF5options and turn java on as follows:



  • Set the HDFLIBS and HDF5LIBS environment variables (setting HDF4 to the HDF5 path turns off HDF4) to the location of HDF4 and HDF5:

HDF5LIBS: C:\Program Files\HDF_Group\HDF5\<path to HDF5 installation>

HDFLIBS:  C:\Program Files\HDF_Group\<path to HDF4 or HDF5 installation>

Set the ANT_HOME and JAVA_HOME environment variables to the location of the software:

JAVA_HOME:  C:\Program Files\<path to openjdk installation>

ANT_HOME:   C:\Program Files\<path to Apache Ant installation>

  • Run ant run and ant package.
