************************************************************************
* Build and Install HDF5 C/C++ Library with CMake *
************************************************************************
Notes: This short instruction is written for users who want to quickly build
HDF5 library and tools from the HDF5 source code package using the
CMake tools.
More information about using CMake can be found at the KitWare site,
www.cmake.org.
CMake uses the command line, however the visual CMake tool is
recommended for the configuration step. The steps are similiar for
all the operating systems supported by CMake.
NOTES:
1. Using CMake for building and using HDF5 is under active development.
While we have attempted to provide error-free files, please
understand that development with CMake has not been extensively
tested outside of HDF. The CMake specific files may change
before the next release.
2. CMake was originally introduced to support development on Windows,
however it should be usable on any system where CMake is supported.
Please send us any comments on how CMake support can be improved on
any system. Visit the KitWare site for more information about CMake.
3. Build and test results can be submitted to our CDash server at:
www.cdash.hdfgroup.org.
Please read the HDF and CDash document at:
www.hdfgroup.org/CDash/HowToSubmit.
========================================================================
Preconditions
========================================================================
1. We suggest you obtain the latest CMake for windows from the Kitware
web site. The HDF5 1.8.x product requires CMake version 2.8.2.
2. If you plan to use Zlib or Szip;
A. Download the packages and install them
in a central location. For example on Windows, create a folder extlibs
and install the packages there. Windows users should also read Section V
in INSTALL_Windows.txt.
B. Use source packages from a SVN server by adding the following CMake
options:
HDF5_ALLOW_EXTERNAL_SUPPORT:STRING="SVN"
ZLIB_SVN_URL:STRING="http://some_location/zlib/trunk"
SZIP_SVN_URL:STRING="http://some_location/szip/trunk"
where "some_location" is the URL to the SVN repository.
C. Use source packages from a compressed file by adding the following CMake
options:
HDF5_ALLOW_EXTERNAL_SUPPORT:STRING="TGZ"
ZLIB_TGZ_URL:STRING="some_location/zlib_src.ext"
SZIP_TGZ_URL:STRING="some_location/szip_src.ext"
where "some_location" is the URL or full path to the compressed file and
ext is the type of compression file.
========================================================================
Building HDF5 C/C++ Libraries with CMake
========================================================================
1. Run CMake
The CMake executable is named "cmake-gui.exe" on Windows and should be
available in your Start menu. For Linux, UNIX, and Mac users the
executable is named "cmake-gui" and can be found where CMake was
installed.
Specify the source and build directories. It is recommemded that you
choose a build directory different then the source directory
(for example on Windows, if the source is at c:\MyHDFstuff\hdf5, then
use c:\MyHDFstuff\hdf5\build or c:\MyHDFstuff\build\hdf5).
OPTIONAL:
Users can perform the configuration step without using the visual cmake-gui
program. We use the file cacheinit.cmake in the config/cmake folder for
our testing. This file enables all the basic options and we turn specific
options on or off for testing using the following command line within the build
directory:
cmake -C <sourcepath>/config/cmake/cacheinit.cmake -G "<generator>" [-D<options>] <sourcepath>
Where <generator> is
* Borland Makefiles
* MSYS Makefiles
* MinGW Makefiles
* NMake Makefiles
* Unix Makefiles
* Visual Studio 10
* Visual Studio 10 Win64
* Visual Studio 6
* Visual Studio 7
* Visual Studio 7 .NET 2003
* Visual Studio 8 2005
* Visual Studio 8 2005 Win64
* Visual Studio 9 2008
* Visual Studio 9 2008 Win64
<options> is:
* SZIP_INCLUDE_DIR:PATH=<path to szip includes directory>
* SZIP_LIBRARY:FILEPATH=<path to szip/library file>
* ZLIB_INCLUDE_DIR:PATH=<path to szip includes directory>
* ZLIB_LIBRARY:FILEPATH=<path to szip/library file>
* <HDF5OPTION>:BOOL=[ON | OFF]
<cacheinit.cmake> is:
# This is the CMakeCache file.
########################
# EXTERNAL cache entries
########################
SET (BUILD_SHARED_LIBS ON CACHE BOOL "Build Shared Libraries" FORCE)
SET (BUILD_TESTING ON CACHE BOOL "Build HDF5 Unit Testing" FORCE)
SET (HDF5_BUILD_CPP_LIB ON CACHE BOOL "Build HDF5 C++ Library" FORCE)

SET (HDF5_USE_H5DUMP_PACKED_BITS ON CACHE BOOL "Use the PACKED BITS feature in h5dump" FORCE)
SET (HDF5_ENABLE_COVERAGE OFF CACHE BOOL "Enable code coverage for Libraries and Programs" FORCE)
2. Configure the cache settings
2.1 Click the Configure button. If this is the first time you are
running cmake-gui in this directory, you will be prompted for the
generator you wish to use (for example on Windows, Visual Studio 9 2008).
CMake will read in the CMakeLists.txt files from the source directory and
display options for the HDF5 project. After the first configure you
can adjust the cache settings and/or specify locations of other programs.
Any conflicts or new values will be highlighted by the configure
process in red. Once you are happy with all the settings and there are no
more values in red, click the Generate button to produce the appropriate
build files.
On Windows, if you are using a Visual Studio generator, the solution and
project files will be created in the build folder.
On linux, if you are using the Unix Makefiles generator, the Makefiles will
be created in the build folder.
2.2 Alternative command line example on Windows in c:\MyHDFstuff\hdf5\build directory:
cmake -C ../config/cmake/cacheinit.cmake -G "Visual Studio 9 2008" \
-DHDF5_ENABLE_SZIP_SUPPORT:BOOL=OFF -DHDF5_ENABLE_Z_LIB_SUPPORT:BOOL=OFF ..
3. Build HDF5
On Windows, you can build HDF5 using either the Visual Studio Environment
or the command line. The command line is used on linux, Unix, and Mac.
To build from the command line, navigate to your build directory and
execute the following;
cmake --build . --config {Debug | Release}
NOTE: "--config {Debug | Release}" may be optional on your platform. We
recommend choosing either Debug or Release on Windows.
3.1 If you wish to use the Visual Studio environment, open the solution
file in your build directory. Be sure to select either Debug or
Release and build the solution.
3.2.1 The external libraries (zlib, szip, and jpeg) can be configured
to allow building the libraries by downloading from a SVN repository.
The option is 'HDF5_ALLOW_EXTERNAL_SUPPORT'; by adding the following
configuration option:
-DHDF5_ALLOW_EXTERNAL_SUPPORT:STRING="SVN"
The options to control the SVN URL (config/cmake/cacheinit.cmake file):
ZLIB_SVN_URL:STRING="http://svn.hdfgroup.uiuc.edu/zlib/trunk"
SZIP_SVN_URL:STRING="http://svn.hdfgroup.uiuc.edu/szip/trunk"
These should be changed to your location.
3.2.2 Or the external libraries (zlib, szip, and jpeg) can be configured
to allow building the libraries by using a compressed file.
The option is 'HDF5_ALLOW_EXTERNAL_SUPPORT'; by adding the following
configuration option:
-DHDF5_ALLOW_EXTERNAL_SUPPORT:STRING="TGZ"
The options to control the SVN URL (config/cmake/cacheinit.cmake file):
ZLIB_TGZ_URL:STRING="some_location/zlib_src.ext"
SZIP_TGZ_URL:STRING="some_location/szip_src.ext"
where "some_location/xxxx_src.ext" is the URL or full path to the
compressed file and where ext is the type of the compression file like:
.bz2, .tar, .tar.gz, .tgz, .zip
4. Test HDF5.
To test the build, navigate to your build directory and execute;
ctest . -C {Debug | Release}
NOTE: "-C {Debug | Release}" may be optional on your platform. We
recommend choosing either Debug or Release to match the build
step on Windows.
5. Packaging HDF5
To package the build into a simple installer using the NullSoft installer NSIS
on Windows, or into compressed files (.tar.gz, .sh, .zip), use the CPack tool.
To package the build, navigate to your build directory and execute;
cpack -C {Debug | Release} CPackConfig.cmake
NOTE: We have just introduced the packaging capability and it has not been
extensively tested. Please send us comments on how it can be improved.
6. The files that support building HDF5 with CMake are all the files in the
config/cmake folder, the CMakeLists.txt files in each source folder, and
CTestConfig.cmake. CTestConfig.cmake is specific to the internal testing
performed by The HDF Group. It should be altered for the users
installation and needs.
7. More information about using CMake can be found at the KitWare site,
www.cmake.org.
