========================================================================
                          Preconditions and Notes
========================================================================

Preconditions:

   1. Installed Microsoft Visual C++ 6.0 or Intel Compiler and WinZip.

      1.1 Installed Intel Compiler 9.1 if you want to build
          HDF5 Fortran libraries.

      Note: By default, WinZip will convert the Unix end of line format
            when extracting .tar file.  This conversion will cause
            "false" failure in some HDF5 tools testings.

            Please uncheck the "TAR file smart CR/LF conversion" option
            in your WinZip to prevent the conversion when extracting
            .tar file.

            To uncheck the "TAR file smart CR/LF conversion" option:

            Invoke WinZip, go to "Options", select "Configuration..."

            Click the "Miscellaneous" tab and uncheck "TAR file smart
            CR/LF conversion" option, then click OK.

   2. Set up a directory structure to unpack the library.  For example:

            c:\                                          (any drive)
            MyHDFstuff\                      (any folder name)

   3. Download the hdf5-1.8.x source code package and use WinZip to
      extract the HDF5 package into c:\MyHDFstuff.  This creates a
      directory called 'hdf5-1.8.x' under MyHDFstuff which contains
      several files and directories.  Rename "hdf5-1.8.x" to "hdf5".

   4. HDF5 provide options to do in-memory compress within HDF5
      library.  Currently, two external compression libraries Zlib and
      Szip can be used with HDF5.

      4.1 HDF5 uses Zlib version 1.2.2 for compression and Zlib is NOT
          distributed with HDF5 library in 1.8.x release. To use Zlib
          library, you have to install your own Zlib DLL library or go
          to ftp://ftp.hdfgroup.org/lib-external/zlib/1.2/bin
          to download the Zlib library.


      4.2 HDF5 uses Szip version 2.0 for compression and Szip
          compression software is provided with HDF5 products in
          1.8.0 release.  To use Szip 2.0 library, you can
          download Szip source codes and binaries from
          ftp://ftp.hdfgroup.org/lib-external/szip/2.0/bin/windows

          Please note that Szip is not a totally open-source free
          software.  For licensing issue of Szip, please check
          "Licensing terms" at
          http://hdfgroup.org/doc_resource/SZIP/index.html.

      Szip compression feature inside HDF5 is optional.

   5. Define the following environment variables:

        HDF5_EXT_ZLIB
        HDF5_EXT_SZIP

      In this section, Zlib and Szip compression packages are assumed
      to be used.  Please read Section V as well as this section if you
      do not want to use compression feature inside HDF5.

      To define these environment variables:

      Click "Start", click "Control Panel", and then double-click
      "System".  On the "Advanced" tab, click "Environment Variables".

      If you are logged on as administrator to the local computer AND
      want to let all other users use these two environment variables,
      click "New" under "System Variables" box; otherwise, click "New"
      under "User Variables" box.

      In the New Variable window, set "Variable name" as HDF5_EXT_ZLIB
      and "Variable value" as zdll.lib, then click OK.

      Similarly, you can set:

      HDF5_EXT_SZIP environment variable as szlibdll.lib

      Notes:

         a. You might have to close and reopen running programs for
            the new environment variable settings to take effect.

         b. c:\zlib122\zlib1.dll and c:\szip\dll\szlibdll.dll should
            be copied into the location that the application can find,
            one suggestion is to use the c:\WINDOWS\system.

   6. Set up path for external libraries and headers

      Skip this part if you don't want to use ANY compression features
      provided by HDF5.  Please do read Section V.

      You have to read this part even if you want to only use Zlib
      or Szip.  You also need to read Section V.

      Invoke Microsoft Visual C++ and go to "Tools" and select
      "Options", find "Directories";

      6.1 Find the box "Show directories for", choose
          "Include files", if you can not find your Zlib and Szip
          header path
          (for example, c:\zlib122\include, c:\szip\include)
          from the directory list, add the header path
          (c:\zlib122\include, c:\szip\include) to the
          included directories.

      6.2 Find the box "Show directories for", choose "Library files",
          If you cannot find your Zlib and Szip library path
          (for example, c:\zlib122\lib, c:\szip\dll)
          from the directory list, add the library path
          (c:\zlib122\lib, c:\szip\dll) to the library directories.

Notes:

   1. In release 1.8.0, all.zip is deprecated. Users should go to
      hdf5/windows directory, run copy_hdf.bat first and then open
      all.dsw under hdf5/windows/proj/all to start building process.

   2. In release 1.8.0, all.sln was provided for command line use ONLY.
      all.sln should never be opened to start building HDF5 using IDE.

   3. To build HDF5 C++ libraries, please read through
      this document.

   4. For users who want to quickly build HDF5 library or do not
      want to know HDF5 building and installation details, please
      read INSATLL_Windows_Short_MSVS6.0.txt,
      INSTALL_Windows_Short_Net.txt or INSTALL_Windows_Short_Intel.txt
      based on the compiler to be used.

   5. For users who would like to build and test HDF5 package from the
      command line, please read INSATLL_Windows_From_Command_Line.txt.

   6. HDF4-related tools are not built and released with HDF5 library
      packages any more. To obtain HDF4 related tools, please check
      http://hdfgroup.org/h4toh5/ and
      ftp://ftp.hdfgroup.org/HDF5/h4toh5

   7. For DLL users, please do read and follow "DLL hints"
      at Section IV.

   8. For .NET users, please read Section VI.

   9. For fortran users, Intel fortran Compiler 9.1 is currently supported-- please
      see Section VII.  Intel Compiler verion 7.x and 8.x are no longer supported,
      but documentation can still be found on the web at 
      http://hdfgroup.org/windows/docs/hdf518/dep/Install_Windows_Dep_Intel.txt

   10. For users who would like to build Muti-threaded version of HDF5
       library, please read Section VIII.

   11. For users who would like to build, test and use HDF5 snapshot
       release, please read Section IX.
   12. For .Net and Intel users, if you are not building HDF5 with
       Thread-Safe Feature (see Section X), ttsafedll.dsp should
       always be turned off.

   13. The Compaq Fortran Compiler is no longer supported in HDF5-1.8.

========================================================================

STEP 1: Building HDF5 libraries and tools

Note:
      1) To build HDF5 with Fortran support, please read over Section VII.


      
   1. Run batch file copy_hdf.bat.

      Go to  c:\MyHDFstuff\hdf5\windows and run copy_hdf.bat. This
      process will copy all the necessary batch files, windows specific
      source codes and text files saved under c:\MyHDFstuff\hdf5\windows
      directory to the corresponding directories under hdf5.

   2. Invoke Microsoft Visual C++ compiler

      Invoke Microsoft Visual C++.  From the main menu, go to "File"
      and select the "Open Workspace" option. Then open the
      c:\MyHDFstuff\hdf5\windows\proj\all\all.dsw workspace.

      You should find windows project files listed as "all files,
      big files etc." on the left.

   3. (Optional)HDF5 C++ and High level C++

      3.1 Skip this step if you do not want to build HDF5 High-Level
          libraries

          Go to "Project" and select "dependencies";
          Select "all" in the "Select project to modify:" box,
          then enable the desired projects:

             hdf5_hl
             hdf5_hldll
             hl_test_image
             hl_test_imagedll
             hl_test_lite
             hl_test_litedll

             hl_test_tabledll
             hl_test_ds
             hl_test_dsdll
             hl_test_packet
             hl_test_packetdll

      3.2 Skip this step if you do not want to build HDF5 High-Level
          C++ libraries

          Go to "Project" and select "dependencies";
          Select "all" in the "Select project to modify:" box,
          then enable all of the project files listed in Section II
          Step 1(3.1) and the following desired projects:

            hdf5_hl_cpp
            hdf5_hl_cppdll
            hl_test_table_cpp
            hl_test_table_cppdll

   4. Select "Build", then Select "Set Active Configuration".

      4.1 To build debug versions of single-threaded static libraries,
      Debug multithreaded DLLs and tests

      In "Project configurations", select "all -- Win32 Debug",
      select "ok". Select "Build" -> "Build" or "Rebuild All" to
      build debug version of project "all".

      4.2 To build release versions of single-threaded static libraries,
      multithreaded DLLs and tests

      In "Project configurations", select "all -- Win32 Release",
      select "ok". Select "Build" -> "Build" or "Rebuild All" to
      build release version of project "all".

      Both debug and release versions must be built.

      Warning messages can be ignored.

      When the debug or release build is done the directories
      listed below will contain the following files:

               hdf5_hl_cppdlld.lib - HDF5 High Level C++ export Library


STEP 2: Testing HDF5 libraries and tools

HDF5 libraries and tools should be tested to make sure that they were
built correctly.

We provide 2 options for users to test HDF5 libraries and tools.

   Option 1: Automatic testings

   HDF5 comes with various test suites, all of which can be tested
   with hdf5check.bat batch file in c:\MyHDFstuff\hdf5 directory.

   hdf5check batch file can be run with one of the following four
   options:

      hdf5check                  test HDF5 C library and tools only

      hdf5check enablecpp        test HDF5 C/C++ libraries and tools
                                 To use this option, HDF5 C++
                                 libraries must have been built
                                 in step I.

      hdf5check enablefortran    test HDF5 C/FORTRAN libraries and
                                 tools
                                 To use this option, HDF5 Fortran
                                 libraries must have been built
                                 in Section VII.

      hdf5check enableall        test HDF5 C/C++/FORTRAN libraries
                                 and tools
                                 To use this option, HDF5 C++ and
                                 Fortran libraries must have been
                                 built in Section VII.

   Invoke a command prompt window and run hdf5check with appropriate
   option.

   Test results are saved in two files:

      c:\MyHDFstuff\hdf5\check_results.txt

      c:\MyHDFstuff\hdf5\tests_results.txt.

   In general, you only need to check tests_results.txt.  If all the
   tests passed, then you do not have to check check_results.txt.
   If some tests failed, check check_results.txt can help you
   figure out what was wrong.

   Option 2: Step-by-step HDF5 libraries and tools testings

   You can also test HDF5 libraries and tools one by one.  There are
   possibly four versions of HDF5 libraries and tools testings.

   They are:

      release version
      release dll version
      debug version
      debug dll version

   We strongly suggest you to redirect your testing results into an
   output file so that you can easily check the testing results. You
   may use either Notepad or WordPad or whatever other windows word
   processor to check the results.  For the purpose of printing,
   please choose font less than 14 for better alignment of the text.

   DLLs listed below should be placed into the Windows system
   directory.  A batch file named install_dll.bat is included in
   c:\MyHDFstuff\hdf5 directory.  Run this batch file and the
   following HDF5 DLLs will be copied to the system directory.

      hdf5\proj\hdf5dll\release\hdf5dll.dll
      hdf5\proj\hdf5dll\debug\hdf5ddll.dll
      hdf5\test\libtestD\release\libtestD.dll
      hdf5\test\libtestD\debug\libtestDd.dll

   1. HDF5 library testing

             type:
                hdf5test release dll >"Your output filename"

             c) debug static version
             type:
                hdf5test debug >"Your output filename"

             d) debug dll version
             type:
                hdf5test debug dll >"Your output filename"

         (2) timing tests

             Go to a) b) c) or d) to test your chosen version

             a) release static version
             type:
                hdf5timingtest release >"Your output filename"

             b) release dll version
             type:
                hdf5timingtest release dll >"Your output filename"

             c) debug static version

 STEP 3: Installing HDF5 Libraries

We provide a batch file for users to relocate all HDF5 libraries in one
folder (C++ and Fortran libraries will also be copied into this folder
if they have been built in step I or Section VII, respectively).  The file
is called installhdf5lib.bat under c:\MyHDFstuff\hdf5 directory.  Run
the batch file, you may see a folder called hdf5lib under c:\MyHDFstuff\hdf5.

The <release> layout of <hdf5lib> should be:

   release\include   --  HDF5 header files
   release\bin       --  HDF5 static tool executables
   release\bindll    --  HDF5 DLL tool executables
   release\lib       --  HDF5 static libraries
   release\dll       --  HDF5 DLLs

You may also find the similar layout for the <debug>.

========================================================================
                 Section I: How To Build Examples (Optional)
========================================================================

Simple examples have been provided for users to test HDF5
C/C++/Fortran and high level C/Fortran library and tools.

Note:
      1) To build HDF5 C++ examples, HDF5 C++ library must have been
         built in step I.

      2) To build HDF5 Fortran or HL Fortran examples, please see 
         Section VII, Step 3.

      3) To build HDF5 High Level C examples, HDF5 High level library
         must have been built in step I.

      4) By default, the debug versions of HDF5 C/C++/HL examples
         are linked with the debug versions of HDF5 C/C++/HL
         libraries and DLLs.  The debug versions of HDF5 C/C++/HL
         examples will fail if they are linked with HDF5 binary
         distribution, which only includes the release versions of
         HDF5 C/C++ libraries and DLLs.

To build and test HDF5 C examples:
----------------------------------

          selectest
          selectestdll
          writetest
          writetestdll

   3. Invoke a command prompt window and run the batch file
      InstallExamples.bat which resides in the top level directory
      (c:\MyHDFstuff\hdf5).  This file creates 4 new directories,
      examplesREL, examplesRELDLL, examplesDBG, and examplesDBGDLL,
      in the c:\MyHDFstuff\hdf5\examples directory and places all the
      executables in it.  Both the release and debug versions of the
      examples should be built before this step is done.

   4. We provide a batch file named testExamples.bat and an expected
      examples tests output file named testExamples_exp_output.txt
      in c:\MyHDFstuff\hdf5\examples directory for you to test HDF5
      C examples.

      testExamples.bat batch file has 4 options:

========================================================================
   Section IV: Building an application using the HDF5 library or DLL
========================================================================

Waring: The instructions below will only describe how to build an
        application using the release version of the HDF5 library or
        DLL.  To use the debug version of the HDF5 library or DLL, you
        need to substitute the release version of the HDF5 library or
        DLL with the debug version.

To use HDF5 static library

  To build an application that uses the HDF5 static library the
  following locations will need to be specified for locating header
  files and linking with the HDF static library, for example:

   c:\MyHDFstuff\hdf5\hdf5lib\release\include
   c:\MyHDFstuff\hdf5\hdf5lib\release\lib

  If you have installed HDF5 library in Section II, step 3.

  We assume that you will use Zlib and Szip compression with HDF5
  library.

  To specify these locations in the settings for your VC++ project,
  you may choose one of the following two methods.

   1) Method One

    To insert the path that specifies HDF5 and Zlib, Szip header files:

    1. Open your VC++ project in Microsoft Visual C++ and make sure it
       is the active project.

    2. Go to the Project menu and chose the "Settings" option.

    3. Choose the build configuration you would like to modify in the
       drop down menu labeled with "Settings For:"

    4. Choose the C/C++ tab

    5. Choose "Preprocessor" in the drop down menu labeled with
       "Category:"

    6. In a text-area labeled with "Additional include directories:",
       add HDF5, Zlib, and Szip header files directories.  For example:

          c:\MyHDFstuff\hdf5\hdf5lib\release\include
          c:\zlib122\include
          c:\szip\include

       Then click OK.

    7. (Optional) To use HDF5 Fortran static library, the location of
       Fortran module files should be specified by following
       Project->Settings->Fortran->Preprocessor, and in a test-area
       labeled with "INCLUDE and USE Paths:", add HDF5 Fortran module
       files directories.  For example:

          c:\MyHDFstuff\hdf5\hdf5lib\release\include

    To link the HDF5 library with your application:

    1. Open your VC++ project in Microsoft Visual C++ and make sure it
       is the active project.

    2. Go to the Project menu and chose "Add to Project" option and
       then "Files" option.

    3. Change the "Files of type:" to "Library Files (.lib)"

    4. Navigate through the directories until you find the location of
       the hdf5.lib.

    5. Select hdf5.lib and click OK.

    6. repeat 1-5, to select zdll.lib and szlibdll.lib.

    7. (optional) repeat 1-5, to select hdf5_cpp.lib to link with HDF5
       C++ static library.

    8. (optional) repeat 1-5, to select hdf5_fortran.lib to link with
       HDF5 Fortran static library.

   2) Method Two

    1. Go to Tools->Options->Directories,

    2. Insert the correct HDF5, Zlib, Szip paths for both headers(include)
       and libraries.  For example,

          c:\MyHDFstuff\hdf5\hdf5lib\release\include
          c:\MyHDFstuff\hdf5\hdf5lib\release\lib
          c:\zlib122\include
          c:\zlib122\lib
          c:\szip\include
          c:\szip\dll

    3. Go to the Project menu and choose the "Settings" option.

    4. Find the "link" option and "Input" category, insert
       "zdll.lib, szlibdll.lib, hdf5.lib".

    5. (Optional) repeat 3-4, to insert "hdf5_cpp.lib" if you want to
       use HDF5 C++ static library.

    6. (Optional) repeat 3-4, to insert "hdf5_fortran.lib" if you want to
       use HDF5 Fortran static library.

    7. (Optional)repeast 3-4, to insert "hdf5_hl.lib" if you want to use
        HDF5 high leve static library.

    7. (Optional) repeat 3-4, to insert "hdf5_hl_cpp.lib" if you want to
       use HDF5 high level C++ static library.

    8. (Optional) repeat 3-4, to insert "hdf5_hl_fortran.lib" if you want to
       use HDF5 high level Fortran static library.


To use the DLL:

    1. Follow the steps for specifying the location of the header files
       as shown above.

    2. Follow the steps for linking the HDF5 library as shown above
       except now link the export library that is created with the DLL.
       The export library is called hdf5dll.lib for HDF5 C libray,
       hdf5_cppdll.lib for HDF5 C++ library, and hdf5_fortrandll.lib
       for HDF5 Fortran library.

    3. Place the DLL in a location that Windows will be able to locate
       it. The searched path and order for DLL's is

       a) The directory where the executable module for the current
          process is located.
       b) The current directory.
       c} The Windows system directory. The GetSystemDirectory function
          retrieves the path of this directory.
       d) The Windows directory. The GetWindowsDirectory function
          retrieves the path of this directory.

         Section V: How to disable Gzip(Zlib)/Szip compression
========================================================================

Warning: When you modify the H5pubconf.h file as described below,
         DO NOT just change the values of these macros from 1 to 0.
         Please DO remove(or comment out) appropriate lines.

   1. Disable Gzip compression

      If you would like to remove Gzip compression from the HDF5
      library, follow the steps below.

      1.1 Open the H5pubconf.h file from the c:\MyHDFstuff\hdf5\src
          directory and remove(or comment out) the following two lines:

             #define H5_HAVE_ZLIB_H 1
             #define H5_HAVE_FILTER_DEFLATE 1

          then save the file.

      1.2 Delete HDF5_EXT_ZLIB environment variable if you have
          set it in preconditions.

      1.3 Run-compile HDF5 library according to Section II.

      When you disable Gzip, you may get the following message
      when building HDF5 libraries:

      The following environment variables were not found
      $(HDF5_EXT_ZLIB)

      This message can be ignored.

   2. Disable Szip compression (both encoder and decoder)

      If you would like to remove Szip compression from the HDF5
      library, follow the steps below.

      2.1 Open the H5pubconf.h file from the c:\MyHDFstuff\hdf5\src
          directory and remove(or comment out) the following two
          lines:

             #define H5_HAVE_SZLIB_H 1
             #define H5_HAVE_FILTER_SZIP 1

          then save the file.

      2.2 Delete HDF5_EXT_SZIP environment variable if you have
          set it in preconditions.

      2.3 Run-compile HDF5 library according to Section II.

      When you disable Szip, you may get the following message
      when building HDF5 libraries:

      The following environment variables were not found
      $(HDF5_EXT_SZIP)

      This message can be ignored.

   Notes:

   To disable Gzip and Szip at the same time, just follow 1.1~1.2
   and 2.1~2.2 and run-compile HDF5 library according to Section II.

   3. Disable Szip encoder

      If you would like to just disable Szip encoder from the HDF5
      library while keeping Szip decoder enabled, follow the steps
      below.

      3.1 Download Szip library without encoder

          Szip library is different if you want to disable Szip encoder.
          Download szip_noencoder binaries from
          ftp://ftp.hdfgroup.org/lib-external/szip/2.0/bin/windows.
          The Szip library and header path should also be set up
          accordingly (refer to precondition 6).

      3.2 Run-compile HDF5 library according to Section II.

          Section VII: How to build HDF5 with Intel Fortran 9.1
========================================================================
Notes:  1. For Intel Compiler users, Intel fortran Compiler 9.1 is currently
        supported-- please see below.  Intel Compiler verion
        7.x and 8.x are no longer supported, but documentation can
        still be found on the web at 
        http://hdfgroup.org/windows/docs/hdf518/dep/Install_Windows_Dep_Intel.txt

        2. The Compaq Fortran Compiler is no longer supported for HDF5 1.8.

        3. Intel Fortran 9.1 works only under .Net 2003 or Visual Studio 2005
        environments
        
        4. For Visual Studio 2005 users, parallel builds should be disabled.  To
        do so: Go to  Tools > Options > Projects and Solutions > Build and Run. 
        Set "maximum number of parallel project builds" to 1.
        


  Preconditions:

     a. Setup Szip Library for Intel Compiler.

     Intel compilers use different Szip library from other compilers.
     Szip source codes or binaries for Intel compiler can be downloaded
     from the following address:

     ftp://ftp.hdfgroup.org/lib-external/szip/2.0/bin/windows.

     b. Set up path for external libraries and headers

      Skip this part if you don't want to use ANY compression features
      provided by HDF5.  Instead, read Section V.

      You have to read this part even if you want to use only Zlib
      or Szip.  You also need to read Section V.

      Invoke Microsoft Visual C++ .Net 2003 or 2005.  From the main
      menu, Go to Tools > Options > Intel(R) Fortran.
      In the right panel, make sure your "Selected Compiler" is Intel Fortran 9.1.
      Click the right-most box for "Libraries",
      Add Zlib and Szip Library Path (c:\zlib122\lib, c:\szip\dll for example)
      Click rightmost box for "Includes",
      Add Zlib and Szip header path (c:\zlib122\include c:\szip\include, for example).
      Then click "OK".

      
  1. Build with Intel Fortran Compiler 9.1 under MSVS C++ .Net 2003 / 2005 Environment

      Note: This step will build HDF5 Static and DLL C and C++
            Library using .Net 2003 or Visual Studio 2005 Compiler as well as
            HDF5 Static and High Level Fortran Library using Intel
            Fortran 9.1 Compiler.


      1.1 Open all.dsw and Convert Project Files (.dsp) to Visual
            C++ .Net Format (.vcproj)

              Invoke Microsoft Visual C++ .Net 2003.  From the main menu, go to
              "File" and select "Open Solution". In the "Open Solution" window,
              Change "Files of type" to "All Project Files". Choose "all.dsw"
              under the directory c:\MyHDFstuff\hdf5\windows\proj\all. In the
              pop up window, choose "Yes To All" to convert all project files
              to Visual C++ .Net project format.

      1.2 Extract Compaq Fortran Project Files

       a. Select project "flush1_fortran" in the Solution Explorer
       window. In the Project menu, select
       "Extract Compaq Visual Fortran Project".

        hl_test_lite_fortrandll
        hl_test_table_fortran
        hl_test_table_fortrandll


       b. Select project "libtest_fortran" in the Solution
       Explorer window. In the Project menu, select
       "Extract Compaq Visual Fortran Project". Since Project
       file "libtest_fortran" contain both C and Fortran code,
       you will be asked to specify which project, either
       Fortran or C/C++, will serve as the main project for
       this mixed language projects. Choose
       "The Intel Fortran project" as the the main project and
       click "OK".

       Do the same thing for hdf5_hl_fortran.

                                     and tools
                                     To use this option, HDF5 C++ and
                                     Fortran libraries must have been
                                     built.

       Invoke a command prompt window and run hdf5check with appropriate
       option.

       Test results are saved in two files:

          c:\MyHDFstuff\hdf5\check_results.txt

          c:\MyHDFstuff\hdf5\tests_results.txt.

       In general, you only need to check tests_results.txt.  If all the
       tests passed, then you do not have to check check_results.txt.
       If some tests failed, check check_results.txt can help you
       figure out what was wrong.

       
       Option 2: Step-by-step HDF5 libraries and tools testings

       Note: This section provides step-by-step instructions for testing the
       Fortran librariy and tools only.  To test the rest of the HDF5 library
       and tools, please see Section II, Step 2.
       
       
       a. Test HDF5 Static Fortran Library

       Go to directory c:\myHDFstuff\hdf5\fortran\test, Run batch file
       testhdf5_fortran.bat with the following two options to test
       fortran static library

         testhdf5_fortran release >> "Your output file name"
         testhdf5_fortran debug   >> "Your output file name"

       Check your output files, there should be no "failures" at all.

       b. Test HDF5 High Level Fortran Library

       Go to directory c:\myHDFstuff\hdf5\hl\fortran\test, Run batch file
       testhdf5_fortran.bat with the following two options to test
       fortran static library

            test_hdf5_hl_fortran release >> "Your output file name"
            test_hdf5_hl_fortran debug   >> "Your output file name"

       Check your output files, there should be no "failures" at all.


  3. (Optional) Build HDF5 Fortan and HL Fortran Examples

           3. Invoke a command prompt window and run the batch file
              Installf90Examples.bat which resides in the top level directory
              (c:\MyHDFstuff\hdf5).  This file creates 4 new directories,
              f90examplesREL, f90examplesRELDLL, f90examplesDBG, and
              f90examplesDBGDLL, in the c:\MyHDFstuff\fortran\examples directory
              and places all the executables in it.  Both the release and debug
              versions of the examples should be built before this step is done.
              
              
        To build and test HDF5 High Level Fortran examples:
        ---------------------------------------------------

           1. Invoke Compaq Visual Fortran 6.6c, open the workspace

            c:\MyHDFstuff\hdf5\windows\hl\fortran\examples\ (continue next line)

                   "Build" -> "Build" or "Rebuild All" to build release version
                   of project "allhlf90examples".

              When the debug build or release build is done, there should be the
              following subdirectories in c:\MyHDFstuff\hdf5\hl\fortran\examples

                  ex_lite
                  ex_litedll

        3. Invoke a command prompt window and run the batch file
              Install_hlf90examples.bat which resides in the top level directory
              (c:\MyHDFstuff\hdf5).  This file creates 4 new directories,
              HLf90examplesRELEASE, HLf90examplesRELEASEDLL, HLf90examplesDEBUG,
              and HLf90examplesDEBUGDLL, in the
              c:\MyHDFstuff\hdf5\hl\fortran\examples directory and places all
              the executables in it. Both the release
              and debug versions of the examples should be built before this
              step is done.

           4. We provide a batch file named test_hl_f90examples.bat in
              c:\MyHDFstuff\hdf5\hl\fortran\examples directory for you to test
              HDF5 high level fortran examples.

              test_hl_f90examples.bat batch file has 4 options:

                 Options                          purpose

                 test_hl_f90examples release      -- for release version

                 test_hl_f90examples release dll  -- for release DLL version

                 test_hl_f90examples debug        -- for debug version

                 test_hl_f90examples debug dll    -- for debug DLL version

              Invoke a command prompt window and run test_hl_f90examples with
              appropriate options.

              When you run "test_hl_f90examples release", the output will look
              like:

                  release  version of High Level Fortran examples     PASSED

              Similar messages should be generated with another three options
              If the high level Fortran examples are built successfully.

========================================================================

Notes: Preconditions and Section I also apply to this section. Users who
       want to build Multi-threaded version of HDF5 library, please read
       those two sections carefully before go to the following part.

1. Run batch file copy_hdf.bat.

   Go to  c:\MyHDFstuff\hdf5\windows and run copy_hdf.bat. This
   process will copy all the necessary batch files,windows specific
   source codes and text files saved under c:\MyHDFstuff\hdf5\windows
   directory to the corresponding directories under hdf5.

2. Invoke Microsoft Visual C++ compiler

   Invoke Microsoft Visual C++.  From the main menu, go to "File"
   and select the "Open Workspace" option. Then open the
   c:\MyHDFstuff\hdf5\windows\proj\all\all.dsw workspace.

   You should find windows project files listed as "all files,
   big files etc." on the left.

3. Please refer to Section II, Step 3(3) to set the dependencies of
   project "all.dsp".

4. Change Project settings

   Choose "Project"->"Settings",

========================================================================
        Section IX: Building and testing HDF5 snapshot release
========================================================================

Note: This section is only for users who would like to build and test
      HDF5 snapshot release.

Step I: Generate H5Tinit.c using Microsoft Visual C++ 6.0

For users who would like to build and test HDF5 C and C++ library ONLY,
it is necessary to manually generate H5Tinit.c before going to
Section II step 1(2). Follow the steps below to generate H5Tinit.c
manually using Microsoft Visual C++ 6.0. We don't guarantee that
H5Tinit.c can be sucesessfully created by other compilers.

 1. Previous step: Section II, step 1(1).

 2. Extra steps:
    1) Open c:\myHDFstuff\hdf5\windows\misc\typegen\typegen.dsw.

    2) Build the project file.

    3) Invoke command prompt and go to c:\myHDFstuff\hdf5\src.

    4) type H5Tinit.exe >H5Tinit.c

    5) Go back to Section II, continue with step 1(2).

Step II: Generate H5f90i_gen.h and H5fortran_types.f90 using Compaq
         Visual Fortran 6.6c

Note: The users who don't want to build fortran library can skip
      this step.

For users who would like to build and test HDF5 with Fortran library.
It is necessary to manually generate the following three files with
the given compiler before go to Section II:

       Files to be Generated    Compiler to be Used

       H5f90i_gen.h             Compaq Visual Fortran 6.6
       H5fortran_types.f90      Compaq Visual Fortran 6.6
       H5Tinit.c                Visual C++ 6.0

We don't guarantee that these three files can be created successfully
by other compilers.

 1) Previous step: Section II, step 1(1)

 2) Follow the steps in Section X, Step I to generate H5Tinit.c.

 3) Open and build H5fortran_detect_gen.dsw with Compaq Visual Fortran

     Go to the following directory
     c:\myHDFstuff\hdf5\windows\misc\H5fortran_detect_gen
     Open H5fortran_detect_gen.dsw with Compaq Visual Fortran and
     build the project file.

 4) Invoke command prompt and go to c:\myHDFstuff\hdf5\fortran\src.
    Type
         H5fortran_detect_gen.exe > H5fortran_detect.f90

 5) Open and build fortrantypegen.dsw with Compaq Visual Fortran

     Go to the following directory
     c:\myHDFstuff\hdf5\windows\misc\fortrantypegen
     Open fortrantypegen.dsw with Compaq Visual Fortran and
     build the project file.

 6) Invoke command prompt and go to c:\myHDFstuff\hdf5\fortran\src.
    Type

          H5fortran_detect.exe > H5fort_type_defines.h

 7) Open and build matchtypegen.dsw with Compaq Visual Fortran
    Go to the following directory
    c:\myHDFstuff\hdf5\windows\misc\matchtypegen
    Open matchtypegen.dsw and build the project file.

 8) Invoke command prompt and go to c:\myHDFstuff\hdf5\fortran\src.
    Type
          H5match_types.exe

    This step will generate H5f90i_gen.h and H5fortran_types.f90
    automatically.

 9) Go back to Section II, step 1(2) to build and test HDF5 Libraries
    and Tools


========================================================================

   beginning of this document also apply to this section. There
   are some extra preconditions for this section only as following.

   pre1. Pthread-Win32 Installed

   Posix Threads for Windows is a open source free software. Users can
   download it from http://sources.redhat.com/pthreads-win32/.

   HDF5 release 1.8.0 supports Pthread-Win32 2.7.0 (2005-06-04) or
   later. Since pthreadVC2.dll used by HDF5 1.8.0 is the release version
   dll of pthread-win32, ONLY HDF5 1.8.0 release dll are supported and
   tested on Windows XP.

   pre2. Set Path for Pthread-Win32 header and library

   Invoke Microsoft Visual C++ 6.0, go to Tools->Options->Directories.

   From the drop-down box under "Show directories for:",

       Choose "Include files", add in the path to Pthread-Win32 header
       file(For example: C:\PTHREADS_WIN32\INCLUDE).

       Choose "Library files", add in the path to Pthread-Winew library
       (For example: C:\PTHREADS_WIN32\LIB).

   pre3. Enable HDF5 Thread-safe Feature on Windows

   Go to directory c:\MYHDFstuff\hdf5\windows\src, open H5pubconf.h and
   find the following messages and remove those comment signs referred to by those
   two arrows and save H5pubconf.h


   /*Users want to build and test hdf5 library with thread safe enabled,
     Make the following block active
   */

       Linked with hdf5 version 1.7 release 51
       Testing  -- multi-dataset creation (dcreate)
       Testing  -- per-thread error stacks (error)
       Testing  -- thread cancellation safety test (cancel)
       Testing  -- multi-attribute creation (acreate)


       All tests were successful.


       Cleaning Up temp files...

   Users who got the same messages as above have successfully built the
   release version of hdf5dll.dll.

3. Build, Test and Install HDF5 Library and Tools

   Go back to Section II, Step I(2) to Build, test and install HDF5
   libary and tools.
========================================================================
Section XI: How to build HDF5 in Visual studio 2005 on windows 32-bit and 64-bit platform
========================================================================
 The building procedure is almost the same as building HDF5 on .Net 2003.
 For 64-bit, currently we only support HDF5 as an 32-bit application and you may need to
 pay attention to the following reminders:
 1) To use zlib or szlib compression packages:
    Use zlib 1.2.2 DLL provided at
    ftp://ftp.hdfgroup.org/lib-external/zlib/1.2/bin/zlib122-windows.tar.gz
    Use szlib 2.0 DLL provided at
    ftp://ftp.hdfgroup.org/lib-external/szip/2.0/bin/windows/xp-net
 2) Make sure that WIN32 macro is set at visual studio 2005.
 3) You may use _CRT_SECURE_NO_DEPRECATE to disable the warnings.
 Please refer to Section VI: How to build HDF5 in Visual Studio .Net 2003.
 Please also note that the example workspace may not work properly. You may need to reset hdf5
 library path.

========================================================================
                            Section XII: Misc.
========================================================================

1. Drivers we support

 The default driver on windows we support is sec2 driver. However, stdio
 driver is also supported. If you want to use stdio driver in your
 application, you may set environment variable HDF5_DRIVER to "stdio".

 On windows XP, the following steps should be followed to set the
 environment variable,

 a) Go to Control panel and find "system",
 b) Click "system" and choose "advanced",
 c) Choose Environment Variables
 d) Add new variable "HDF5_DRIVER"
 e) set the "HDF5_DRIVER" to "stdio"

 Reminder: if you don't want to use stdio driver, please remember to
 delete the environment variable "HDF5_DRIVER" or change the variable
 value to "sec2".

2. Helpful Pointers

Here are some helpful notes if you are not familiar with
using the Visual C++ Development Environment.

    2.1 Project name and location issues:

    If you must install all.dsw and all.dsp in another directory,
    relative to hdf5 directory, you will be asked to locate the
    sub-project files, when you open the project all.dsw.

    If you want to rename all (the entire project), you will need to
    modify two files all.dsw and all.dsp as text (contrary to the
    explicit warnings in the files).

    You can also modify all.dsw and all.dsp as text, to allow these 2
    files to be installed in another directory.


    2.2 Settings... details:

    If you create your own project, the necessary settings can be read
    from the all.dsp file(as text), or from the Project Settings in the
    Developer Studio project settings dialog.

    Project
       Settings
          C/C++
             Category
                Code Generation
                   Use run-time Library
                      These are all set to use Single-Threaded

    2.3 DLL... hints:

    If you want to use DLL versions of HDF5 library in your application,
    you should
      1) put HDF5 DLL into windows system directory

      2) add HDF5 DLL export library into your project

      3) Follow "Settings... details" into the last line:
         change Single-Threaded into Multithreaded DLL or
         Debug Multithreaded DLL

      4) Follow "Settings.. details" into PreProcessor:
         Project
            Settings
               C/C++
                  Category
                     PreProcessor

        Find PreProcessor definations and Add _HDF5USEDLL_ at the
        end of the PreProcessor definitions to use HDF5 C DLL.

      5)(optional) repeat 4), add HDF5CPP_USEDLL at the
        end of the PreProcessor definitions to use HDF5 C++ DLL.

      6) (optional) repeat 4), add _HDF5USEHLDLL_ at the
         end of the PreProcessor definitions to use HDF5 high level
         DLL.

      7) (optional) repeat 4), add HDF5USE_HLCPPDLL at the
         end of the PreProcessor definitions to use HDF5 high level C++
         DLL.

      8) (optional) Follow Project->Settings->Fortran->Category->
         General->Predefined Preprocess or Symbols, and add
         "HDF5F90_WINDOWS" to use HDF5 Fortran DLL.

3. Backward compatibility with 1.6
    If you are going to use 1.6 APIs with 1.8 branch, you may do the following two things:
    3.1 Uncomment out /*#define H5_WANT_H5_V1_6_COMPAT 1*/ inside h5pubconf.h under windows\src.
    3.2 Set up an environment variable H5_WANT_H5_V1_6_COMPAT to 1, this will be used to test compatibility
        of error APIs.
    Remember to undo 1 and 2 after you test if you are not going to use 1.6 backward compatibility option.
