************************************************************************ * Build and Install HDF5 Examples with CMake * ************************************************************************ Notes: This short instruction is written for users who want to quickly build HDF5 Examples 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 available for the configuration step. The steps are similar for all of 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 for HDF5 development 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. ======================================================================== I. Preconditions ======================================================================== 1. We suggest you obtain the latest CMake for windows from the Kitware web site. The HDF5 1.8.x product requires a minimum CMake version of 3.1.0. 2. You have installed the HDF5 library built with CMake, by executing the HDF Install Utility (the *.exe file in the binary package for Windows). If you are using a Windows platform, you can obtain a pre-built Windows binary from The HDF Group's website at www.hdfgroup.org. 3. Set the environment variable HDF5_DIR to the installed location of the config files for HDF5. On Windows: HDF5_DIR=C:/Program Files/HDF_Group/HDF5/1.8.x/cmake (Note there are no quote characters used on Windows and all platforms use forward slashes) 4. Created separate source and build directories. (CMake commands are executed in the build directory) ======================================================================== II. Building HDF5 Examples with CMake ======================================================================== Go through these steps to build HDF5 applications with CMake. 1. Run CMake 2. Configure the cache settings 3. Build HDF5 Examples 4. Test HDF5 Examples. These steps are described in more detail below. 1. Run CMake The visual 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. Make the build and source directories different. For example on Windows, if the source is at c:\MyHDFstuff\hdf5, then use c:\MyHDFstuff\hdf5\build or c:\MyHDFstuff\build\hdf5 for the build directory. PREFERRED: Users can perform the configuration step without using the visual cmake-gui program. The following is an example command line configuration step executed within the build directory: cmake -G "" [-D] Where is * Borland Makefiles * MSYS Makefiles * MinGW Makefiles * NMake Makefiles * Unix Makefiles * Visual Studio 11 * Visual Studio 11 Win64 * 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 is: * BUILD_TESTING:BOOL=ON * BUILD_SHARED_LIBS:BOOL=[ON | OFF] * HDF_BUILD_FORTRAN:BOOL=[ON | OFF] 2. Configure the cache settings 2.1 Visual CMake users, 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 10). 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 -G "Visual Studio 10" -DBUILD_TESTING:BOOL=ON -DBUILD_SHARED_LIBS:BOOL=ON .. 3. Build HDF5 examples On Windows, you can build HDF5 applications using either the Visual Studio Environment or the command line. The command line is normally 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. If you are using the pre-built binaries from HDF, use Release. 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. 4. Test HDF5 Examples. 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. The files that support building with CMake are all of 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 user's installation and needs. The cacheinit.cmake file settings are used by The HDF Group for daily testing. It should be altered/ignored for the user's installation and needs. ======================================================================== III. Using HDF5 Libraries with Visual Studio 2008 ======================================================================== 8. Set up path for external libraries and headers Invoke Microsoft Visual Studio and go to "Tools" and select "Options", find "Projects", and then "VC++ Directories". 8.1 If you are building on 64-bit Windows, find the "Platform" dropdown and select "x64". 8.2 Find the box "Show directories for", choose "Include files", add the header path (i.e. c:\Program Files\HDF Group\HDF5\hdf5-1.8.x\include) to the included directories. 8.3 Find the box "Show directories for", choose "Library files", add the library path (i.e. c:\Program Files\HDF Group\HDF5\hdf5-1.8.x\lib) to the library directories. 8.4 If using Fortran libraries, you will also need to setup the path for the Intel Fortran compiler. ************************************************************************ Need further assistance, send email to help@hdfgroup.org
