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

Preconditions:

   1. Installed Microsoft Visual Studio .Net or Visual Studio 2005.
   
   2. (Optional) Installed Intel Compiler 9.1 if you want to build HDF5 Fortran 
      libraries.
      
   3. Install Winzip or 7-zip for extracting source tarball.

      Note: 1. 7zip is an open-source alternative to WinZip.  Some of the
            advanced functionality is disabled in WinZip unless you buy the
            software.  With 7zip, most of this functionality is included for
            free.
      
            2. 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.

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

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

   5. Download the hdf5-1.8.x source code package and use 7zip or 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".

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

      6.1 HDF5 uses Zlib version 1.2.3 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/zlib123-windows.zip
          to download the Zlib library.


      6.2 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.

   7. 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 will have to close and reopen running programs for the new 
            environment variable settings to take effect.

         b. c:\zlib123\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 Studio and go to "Tools" and select "Options", 
      find "Projects", and then "VC++ 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:\zlib123\include, c:\szip\include) from the directory list, add the 
          header path (c:\zlib123\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:\zlib123\lib, c:\szip\dll) from the directory list, add the library 
          path (c:\zlib123\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. Users who prefer to use Visual Studio 6.0 can follow instructions in 
      INSTALL_Windows_Short_MSVS6.0.txt.  Note, however, that Visual Studio
      6.0 will not be supported in future versions of HDF5.
      
   3. For users who want to quickly build HDF5 library or do not want to know 
      HDF5 building and installation details, please read the 
      INSTALL_Windows_Short_***.txt relating to your compiler.

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

   5. 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

   6. For Fortran users, Intel fortran Compiler 9.1 is currently supported-- 
      please see Section VI.  Intel Compiler verion 7.x and 8.x are no longer 
      supported.

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

   8. For users who would like to build, test and use HDF5 snapshot
      release, please read Section VIII.

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

Note:
      To build and test HDF5 with Fortran support, please read over Section VI.

      
STEP 1: Building HDF5 Libraries and Tools

      
   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 Studio compiler

      Invoke Microsoft Visual Studio.  From the main menu, go to "File" and 
      select the "Open Solution" option. Then open the
      c:\MyHDFstuff\hdf5\windows\proj\all\all.sln solution.

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

   3. (Optional) Disable HDF5 C++ and High level C++
   
      In HDF5 1.8, C++ and HL C++ libraries are built by default.  To opt-out,
      you must explicitly disable them.

      3.1 Skip this step if you do want to build HDF5 High-Level C++ libraries

          Go to "Project" and select "Project Dependencies".  Select "all", and 
          disable all of the following projects:

            hdf5_hl_cpp
            hdf5_hl_cppdll
            hl_test_table_cpp
            hl_test_table_cppdll
      
      3.2 Skip this step if you do want to build HDF5 High-Level libraries

          Go to "Project" and select "Project Dependencies".  Select "all", and 
          disable all of the project files listed in the previous step, as well
          as the following projects:

             hdf5_hl
             hdf5_hldll
             hl_test_image
             hl_test_imagedll
             hl_test_lite
             hl_test_litedll
             hl_test_table
             hl_test_tabledll
             hl_test_ds
             hl_test_dsdll
             hl_test_packet
             hl_test_packetdll


   4. Select "Build", then Select "Configuration Manager".

      4.1 To build debug static libraries, debug multithreaded DLLs, and tests:

      In "Active Solution Configuration", select "Debug". Select "Close". 
      Select "Build" -> "Build Solution" or "Rebuild Solution" to build debug 
      version of project "all".

      4.2 To build release static libraries, multithreaded DLLs and tests:

      In "Active Solution Configuration", select "Release". Select "Close". 
      Select "Build" -> "Build Solution" or "Rebuild Solution" 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 VI.

      hdf5check enableall        Test HDF5 C/C++/Fortran libraries 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

   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.

   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

      Open a command prompt in the hdf5\test directory

         (1) Basic tests

             a) Release Static, type:
                hdf5test release >"Your output filename"

             b) Release DLL, type:
                hdf5test release dll >"Your output filename"

             c) Debug Static, type:
                hdf5test debug >"Your output filename"

             d) Debug DLL, type:
                hdf5test debug dll >"Your output filename"

         (2) Timing Tests

             a) Release Static, type:
                hdf5timingtest release >"Your output filename"

             b) Release DLL, type:
                hdf5timingtest release dll >"Your output filename"

             c) Debug Static, type:
                hdf5timingtest debug >"Your output filename"

             d) Debug DLL, type:
                hdf5timingtest debug dll >"Your output filename"

      Use a text editor to check results. You should not find any FAILED marks 
      in your output files.

   2. HDF5 tools testing

      To test HDF5 tools, cd back into hdf5 directory and then to tools 
      directory (c:\MyHDFstuff\hdf5\tools).  The HDF5 tools testing results are 
      saved into output files in tools directory by the testhdf5tools.bat as 
      described below.

         a) Release Static, type:
            testhdf5tools release
         Output file: toolstest_release.txt

         b) Release DLL, type:
            testhdf5tools release dll
         Output file: toolstest_releasedll.txt

         c) Debug Static, type:
            testhdf5tools debug
         Output file: toolstest_debug.txt

         d) Debug DLL, type:
            testhdf5tools debug dll
         Output file: toolstest_debugdll.txt

      Use a text editor to check results. You should not find any FAILED marks 
      in your output files.

   3. HDF5 C++ library test

      Skip this step UNLESS you have built HDF5 C++ libraries and want to test 
      them.

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

         hdf5\proj\hdf5_cppdll\release\hdf5_cppdll.dll
         hdf5\proj\hdf5_cppdll\debug\hdf5_cppddll.dll

      Run hdf5cpptest.bat in the hdf5\c++\test directory at the
      command prompt as below:

         a) Release Static, type:
            hdf5cpptest release >"Your output filename"

         b) Release DLL, type:

 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 VI, 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 III: 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 VI, 
         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:
----------------------------------
   1. Invoke Microsoft Visual Studio, go to "File" and select the "Open 
      Solution" option.

      Then open the solution
      c:\MyHDFstuff\hdf5\windows\examples\allexamples\allexamples.sln.

   2. Select "Build", and "Configuration Manager".

       2.1 To build debug versions of C examples:
       
          In "Active Solution Configuration", select "Debug". Select "Close". 
          Select "Build" -> "Build Solution" or "Rebuild Solution" to build 
          debug version of project "allexamples".

       2.2 To build release versions of C examples.
       
          In "Active Solution Configuration", select "Release". Select "Close". 
          Select "Build" -> "Build Solution" or "Rebuild Solution" to build 
          release version of project "allexamples".

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

          attributetest
          attributetestdll
          chunkread
          chunkreaddll
          compoundtest

          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:

         testExamples release     -- for release version

         testExamples release dll -- for release DLL version

         testExamples debug       -- for debug version

         testExamples debug dll   -- for debug DLL version

      Invoke a command prompt and run testExamples.bat with appropriate options.
      You should get "All HDF5 C examples tests passed." when the C examples are
      built successfully.  Otherwise, the difference between the expected 
      outputs and actual outputs will be given.

========================================================================
   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 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.

1. Specifying Include Directories

To specify the include directories in the settings for your Visual Studio 
project, you may choose one of the following two methods.

  Method One: Project-wide Settings

    1. Open your project in Microsoft Visual Studio and make sure it is the 
       active project.

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

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

    4. Choose the "C/C++" tab, anc select "General".

    5. 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:\zlib123\include
          c:\szip\include

       Then click OK.

    6. (Optional) To use HDF5 Fortran static library, the location of 
       Fortran module files should be specified by following Project->
       Settings->Fortran->Preprocessor, and in the text-area labeled 
       "Additional Include Directories", add HDF5 Fortran module files 
       directories.  For example:

          c:\MyHDFstuff\hdf5\hdf5lib\release\include
          
  Method Two: Visual Studio Settings

    1. In Visual STudio, go to Tools->Options->Projects->
       VC++ 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:\zlib123\include
          c:\zlib123\lib
          c:\szip\include
          c:\szip\dll

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

2. Specifying Linking Directories

  To link the HDF5 static library with your application:

    1. In Visual Studio, go to the Project menu and choose "Properties".

    2. Find the "Link" option and "Input" category.  In the "Additional
       Dependencies" field, insert "zdll.lib, szlibdll.lib, hdf5.lib".

    3. (Optional) Also insert "hdf5_cpp.lib" if you want to use HDF5 C++ 
       static library.

    4. (Optional) Also insert "hdf5_fortran.lib" if you want to use HDF5 
       Fortran static library.

    5. (Optional) Also insert "hdf5_hl.lib" if you want to use HDF5 high 
       level static library.

    6. (Optional) Also insert "hdf5_hl_cpp.lib" if you want to use HDF5 High
       Level C++ static library.

    7. (Optional) Also insert "hdf5_hl_fortran.lib" if you want to use HDF5 
       High Level Fortran static library.


  To link the HDF5 DLL library with your application:

    1. Follow the steps for linking the HDF5 static 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.
       
    2. In the Project Properties dialog, go to the C/C++ > Preprocessor
       subsection.  In the "Preprocessor Definitions" box, add "_HDF5USEDLL_"
       to the list.
       
    3. (Optional) Also add HDF5CPP_USEDLL to use HDF5 C++ DLL.

    4. (Optional) Also add _HDF5USEHLDLL_ to use HDF5 high level DLL.

    5. (Optional) Also add HDF5USE_HLCPPDLL use HDF5 high level C++ DLL.

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

    7. Place the DLLs in a location that Windows will be able to locate.  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.
       e) The directories listed in the PATH environment variable.

========================================================================
         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.

   Notes:

   To disable Gzip and Szip at the same time, just make the appropriate
   modifications to H5pubconf.h and the environmental variables all together,
   and then Run-compile.
         
   1. Disable Gzip (Zlib) 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.

   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 VI: 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.

        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.

        1) Invoke Microsoft Visual C++ .Net 2003 or 2005.  
        
        2) 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.
      
        3) Select the right-most box for "Libraries", and add Zlib and Szip 
           library paths (c:\zlib123\lib, c:\szip\dll for example).
      
        4) Select right-most box for "Includes", and add Zlib and Szip header 
           paths (c:\zlib123\include c:\szip\include, for example).
           
        5) Then click "OK".

      
1. Build with Intel Fortran Compiler 9.1 under Visual Studio .Net / 2005

  Note: This step will build HDF5 Static and DLL C and C++ Library using .Net
        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_fortran.sln

      Invoke Microsoft Visual C++ .Net or 2005.  From the main menu, 
      go to "File" and select "Open Solution".  Choose "all_fortran.sln" 
      under the directory c:\MyHDFstuff\hdf5\windows\proj\all_fortran.


  (.Net 2003 ONLY) Fix Runtime Libraries
  
    Due to a incompatibilities between Visual Studio .Net, Intel Fortran 9.1,
    and the Microsoft Platform SDK, the static debug run-time libraries cannot
    be used for some Fortran projects.  To remedy this, make the following
    changes:
    
        a) Select the "flush1_fortran" project, and go to Project->Properties.
        
        b) Make sure "Debug" is selected in the "Configuration" drop-down.
        
        c) From the Properties dialog, navigate to Fortran->Libraries.
        
        d) In the field "Runtime Library", select "Single-threaded".
        
        e) Do the same for projects "flush2_fortran", and "testhdf5_fortran".

    
  1.2 Build as Normal

    Follow steps as in Section II to build all HDF5 library files, including
    Fortran and HL Fortran libraries.


2. Test HDF5 Static and High Level Fortran Library

    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 used to test HDF libraries with Fortran with
       the following options:

          hdf5check enablefortran    Test HDF5 C/Fortran libraries and tools


          hdf5check enableall        Test HDF5 C/C++/Fortran libraries 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"

      Use a text editor to check results. You should not find any FAILED marks 
      in your output files.

       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"

      Use a text editor to check results. You should not find any FAILED marks 
      in your output files.


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

    Note: This section only covers building Fortran and HL Fortran examples.

              rwdsetexampletestdll
              selecteletest
              selecteletestdll

       3. Invoke a command prompt 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. Open allhlf90examples.sln

          Invoke Microsoft Visual C++ .Net or 2005.  From the main menu, 
          go to "File" and select "Open Solution".  Choose 
          "allhlf90examples.sln" under the directory 
          c:\MyHDFstuff\hdf5\windows\hl\fortran\examples\allhlf90examples.        

       2. Select "Build", then Select "Configuration Manager".

        2.1 To build debug versions of Fortran examples.

          In "Active Solution Configuration", select "Debug". Select "Close". 
          Select "Build" -> "Build Solution" or "Rebuild Solution" to build 
          debug version of project "allhlf90examples".

        2.2 To build release versions of Fortran examples.

          In "Active Solution Configuration", select "Release". Select "Close". 
          Select "Build" -> "Build Solution" or "Rebuild Solution" 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 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 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.

========================================================================
   Section VII : How to build Multi-threaded version of HDF5 library
========================================================================

Notes: In Visual Studio 2005, the Single-threaded runtime libraries have been
       depreciated, and Multi-threaded is built by default.  Therefore, no extra
       work needs to be done to build Multi-threaded libraries in Visual Studio
       2005.

       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.

       
In Visual Studio .Net, users have the option of building multi-threaded
libraries by manipulating the project settings.  Otherwise, the build process
is very much the same.  Therefore, follow the instructions below, and refer
to the earlier sections of this document for details on building and testing.


1. Open the solution file

    Refer to previous sections to open the appropriate solution file,
    depending on whether you are building with or without Fortran libraries.
        
2. Change Project Settings

    a) In Visual Studio, go to "Projects->Properties".

    b) Make sure in the "Configuration" box, "Release" is selected.
    
    c) Select all of the static project file in the main window by holding 
       the "Ctrl" key while clicking the project file name.
       
    d) In the "Properties" window, choose "C/C++", and then "Code
       Generation".
       
    e) Under "Run-time Library", "Single-Threaded" should appear. If it is 
      blank inside this box, check if you highlight some DLL project files. 
      
    d) Change "Single-Threaded" to "Multithreaded".

    e) In the "Configuration" box, change to "Debug", keeping the static
       projects selected.

    f) Under "Run-time Library", change "Debug Single-Threaded" to "Debug 
       Multithreaded".

3. Build as Normal

    Refer to previous sections to build and test the HDF5 libraries
    and tools.
    
    
========================================================================
        Section VIII: Building and testing HDF5 snapshot release
========================================================================

Note: This section is only for users who would like to build and test HDF5 
      snapshot release.  These releases are development builds, and are
      unstable!  Use for testing only, and backup any data which will be
      manipulated.

Step I: Generate H5Tinit.c using Microsoft Visual Studio

For users who would like to build and test HDF5 C and C++ library ONLY, it is 
necessary to manually generate H5Tinit.c before building HDF5.  Follow the steps 
in Section XII to generate H5Tinit.c manually using Microsoft Visual Studio 6.0. 
We don't guarantee that H5Tinit.c can be sucesessfully created by other 
compilers.


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) 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.

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

 3) 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.

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

          H5fortran_detect.exe > H5fort_type_defines.h

 5) 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.

 6) 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.

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


========================================================================
    Section IX: How To Build And Test HDF5 With Thread-Safe Feature
========================================================================

   All of the preconditions in "Preconditions" Section at the 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 Studio, go to Tools->Options->Projects->VC++ 
   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

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 X: How to build HDF5 in Visual Studio 2005
========================================================================
 
 The building procedure is almost the same as building HDF5 on .Net 2003.
 Please refer to Section VI: How to build HDF5 in Visual Studio .Net 2003.

 
========================================================================
            Section XI: How to build HDF5 for 64-bit Windows
========================================================================

HDF5 can be built for 64-bit Windows in Visual Studio .NET 2003 or Visual
Studio 2005.  Visual Studio 2005 offers much greater support, and the build
process is much more straight-forward, so we recommend all users switch to 
Visual Studio 2005 for 64-bit builds.  However, we still provide instruction
for .NET.

Notes:
  
    1. 32-bit binaries cannot be linked with 64-bit binaries, and therefore
       external libraries (szip and zlib. and currently not supported.  In the
       future we plan to build these libraries natively and offer support.
       
    2. Fortran libraries are currently untested and unsupported.
    
    3. Building 64-bit HDF5 from a 32-bit machine is also unsupported.  Because 
       we generate H5tinit.c from a generated 64-bit executable, this must be
       done on a 64-bit machine.
    
    
Prerequisites:

    1. A 64-bit Windows machine.  Either AMD64 and Itanium is supported.
    
    2. Either Visual Studio .NET or 2005.  Visual Studio 2005 is recommended.
    
    3. If building with .NET, the lastest version of the Windows Platform SDK
       must be installed.  The latest version can be found at:
          http://www.microsoft.com/msdownload/platformsdk/sdkupdate/
       If building with 2005, Visual Studio must have been installed with the
       x64 compiler tools.
       

Building:

    1. Copy Windows-related files
    
        From the directory .\windows, run copy_hdf.bat.  This will copy
        Windows-related files to their neccessarily locations within the source
        directory.
        
    2. Open the IDE

        For Visual Studio 2005, this simply involves opening as normal.
        
        In .NET, you must first open a 64-bit build environment command prompt.
        To do this, go to the start menu and open Microsoft Platform SDK,
        Open Build Environment Window, Windows XP 64-bit Build Environment,
        and Set Windows XP x64 Build Env (Retail).  This sets up the neccessary
        path for Visual Studio.  .NET must then be launched from that command
        prompt.  This can be done by issuing the command:
        
          start "" "C:\Program Files (x86)\Microsoft Visual Studio .NET 2003\
          Common7\IDE\devenv.exe" /useenv
            
    
    3. Generate H5tinit.c
        
        Follow the instructions in Section XII to generate H5tinit.c
                        
    4. Build the library
        
        4.1 Open the workspace all.sln from the folder .\windows\proj\all.  If
            using Visual Studio .NET, this should be launched from the same 
            window, or open another window the same way you did in Step 2.
            
        4.2 Select the Target Machine
        
            In the same way you did in Step 3.2, set the Target Machine for
            64-bit.  If using .NET, this needs to be done for all projects
            that produce an executable or dll.  You can recognize these because
            in the Property dialog, they have a "Linker" section, rather than
            a "Librarian" section.
          
        4.3 Modify Project Settings
        
            Similar to Step 3.3, we must remove "gethostname@8" from the list of
            "Force Symbol References" for each project that has it.  Although
            tedious, this must be done, or Visual Studio will issue a linker
            error.  For Visual Studio 2005, this must be done for both debug
            and release versions.  In .NET, we only build release.
            
            In .NET, we also need to add "bufferoverflowU.lib" as a dependency
            for several projects.  You can simply add it to all projects that
            produce an executable or dll, or identify specific projects that
            need it at build-time because they will fail with a link error
            such as:
                error LNK2001: unresolved external symbol __security_cookie
                this library must be explicitly added for that project.
                
        4.4 Modify H5pubconf.h
        
            Open H5pubconf.h from the .\src directory.  Because we are not using
            zlib or szip libraries, we must comment out the following lines:
            
                #define H5_HAVE_FILTER_DEFLATE 1
                #define H5_HAVE_ZLIB_H 1
                
                #define H5_HAVE_SZLIB_H 1
                #define H5_HAVE_FILTER_SZIP 1

        4.5 Disable projects
        
            In Visual Studio, open the configuration manager and disable 
            ttsafedll.  If you aren't using the C++ library, you may disable 
            those projects as well.  For Visual Studio 2005, this must be done 
            for both Release and Debug versions.
            
        4.6 Build
        
            In Visual Studio, select Build, Build Solution.  In Visual Studio
            2005, you may build Debug and Release versions, but in .NET, only
            release builds are supported.
        
        
Testing:
    
    We provide a test suite to verify all libraries and tools were built
    successfully.  This test suite should work identically on 32- and 64- bit
    builds.
    
    Note that because 64-bit binaries were built, these tests must run on a
    64-bit machine.
    
    If built with Visual Studio 2005, simply open a command prompt, and from
    the root hdf5 directory, issue the command "hdf5check".  If C++ libraries
    were built, you may test them at the same time with the command
    "hdf5check enablecpp".
    
    If built with Visual Studio .NET, debug versions of the library will not
    be present, and the test scripts must be altered by hand to reflect this.
    In a text editor, open hdf5check.bat from the root hdf5 folder, and comment
    or remove test sections for "Debug" or "Debug DLL".  The layout is fairly
    straight-forward, but as an alternative, you may manually run each of the
    other various sub- test scripts with the "release" and "release dll"
    parameters.
    
    
Installing:

    We provide a script that will install all headers, libraries, and tools
    into one folder, hdf5lib.  From the root hdf5 directory, run the script
    "installhdf5lib.bat".  This will create the hdf5lib folder, and create
    subdirectories containing all relevent files.  This should work identically
    on 32- an 64-bit Windows.
 
 
========================================================================
                  Section XII: How to generate H5tinit.c
========================================================================

In HDF5, H5tinit.c is used to to describe the byte-order and floating point
format of the current machine.  On Linux, this is automatically generated.
On Windows, we provide it pre-genearated, although users may generate their own.

It is recommended to generate H5tinit.c on your own if you are using any
advanced configuration.  This might include:

    - 64-bit Windows
    - File systems other than NTFS
    - Versions of Windows other than Windows XP
    - Run-time libraries other than those distributed with Visual Studio
    
To generate your own H5tinit.c, follow the steps below.
        
    1. Open the solution typegen.sln from the folder .\windows\misc\typgen.
        
    2. Edit the code
	
	   Open the source file H5detect.c, and remove or comment the line:
	   
		siglongjmp(jbuf_g, 1);
		
	   This function is unsupported on Windows, and will cause Visual Studio
	   2005 to crash.
	   
    3. Build H5tinit.exe
    
        Make sure your configuration is set to Debug, and build the project.  
        This will generate H5tinit.exe in the .\src folder.
        
    4. Create H5tinit.c
    
        From a command prompt, go to the .\src directory and issue the command:
            .\H5tinit.exe > H5tinit.c
        This will generate our H5tinit.c file.
        

Note:

    If you are building on 64-bit Windows, make sure you set your build
    "Machine Type" to "X64".  Also, you will need to comment out any lines
    referencing "siglongjmp", as this function is not present on 64-bit Windows.

                            Section XIII: Misc.
========================================================================

1. Helpful Pointers

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

    1.1 Project name and location issues:

    It is recommended that you use the given directory structure for building
    HDF5.  However, it is possible to create your own structure.  If you must 
    install all.sln and all.vcproj in another directory, relative to hdf5 
    directory, you will be asked to locate the sub-project files, when you open 
    the project all.sln.

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


    1.2 Settings... details:

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

    
2. 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.
