## Preconditions

Please read CAREFULLY about the following preconditions and notes first.

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

> Installed Compaq Visual Fortran compiler(6.0 or higher version), or Intel Fortran compiler if you want to build HDF5 Fortran libraries.

> Notes:

> 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

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.

- 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/szip/2.0/bin/windows/ to download the Zlib library.

  Notes:

  1. Zlib 1.2.2 DLL library can also be downloaded from ftp://ftp.hdfgroup.org/lib-external/zlib/1.2/bin

- 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/

  3. 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" -> "Control Panel" -> "System" -> "Advanced" -> "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

"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";

- 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.

- 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++ and FORTRAN 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.txt.

- 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-releated tools, please check

  http://hdfgroup.org/h4toh5/

  ftp://ftp.hdfgroup.org/HDF5/h4toh5

- 7. For DLL users, please do read and follow "DLL Hints" Section IV.

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

- 9. For Intel Compiler users, Intel 7.x works with MSVS 6.0 and Intel 8.1 only works with MSVS .net 2003 when you build HDF5-1.8.x.

- 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.

### 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:

Options | Illustration
--- | ---
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 step I.
hdf5check enableall | test HDF5 C/C++/FORTRAN libraries and tools To use this option, HDF5 C++ and Fortran libraries must have been built in step I.

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 four versions of HDF5 libraries and tools testing. 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

  Notes:

  Use Notepad or WordPad to check results. You should not find any FAILED marks in your output files.

- ##### 2. HDF5 tools testing

  To test HDF5 tools, go to 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.

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

  - ##### a. release static version

    type:

    testhdf5tools release

    output file: toolstest_release.txt

  - ##### b. release dll version

    type:

    testhdf5tools release dll

    output file: toolstest_releasedll.txt

  - ##### c. debug static version

    type:

    testhdf5tools debug

    output file: toolstest_debug.txt

  - ##### d. debug dll version

    type:

    testhdf5tools debug dll

    output file: toolstest_debugdll.txt

  Notes:

  Use Notepad or WordPad 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 to 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

### 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). 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 IV: Building an application using the HDF5 library or DLL

  Warnings:

  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.

  - ### 1. To use HDF5 static library

    - To build an application using 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.

      - #### 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 the "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 step i-v, to select zdll.lib and szlibdll.lib.

          7. (optional) repeat step i-v, to select hdf5_cpp.lib to link with HDF5 C++ static library.

          8. (optional) repeat step i-v5, to select hdf5_fortran.lib to link with HDF5 Fortran static library.

      - #### 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 step iii-iv, to insert "hdf5_cpp.lib" if you want to use HDF5 C++ static library.

        > 6. (Optional) repeat step iii-iv, to insert "hdf5_fortran.lib" if you want to use HDF5 Fortran static library.

  - ### 2. To use HDF5 Dynamic Link Library

    > 1. Follow the steps for specifying the location of the header files as shown in Method One.

    > 2. Follow the steps for linking the HDF5 library as shown in Method One. 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

    >    1. The Windows system directory. The GetSystemDirectory function retrieves the path of this directory.

    >    2. The Windows directory. The GetWindowsDirectory function retrieves the path of this directory.

    >    3. The directories listed in the PATH environment variable.

    > 4. To modify your own application settings, please DO FOLLOW the "DLL Hints" at Section XI "HELPFUL POINTERS".

  ## Section XI: How to build HDF5 in Visual studio 2005 on windows 32-bit and 64-bit platform

  Notes:

  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.

  Go to TOP Section XI

  Go to Table of Contents

  ## 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 notes that may be of help 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 two 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) 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.
