************************************************************************ * Build and Install HDF5 Applications with CMake * ************************************************************************ Notes: This short instruction is written for users who want to quickly build HDF5 applications using the CMake tools. Users can adapt these instructions for their own applications. For more information, see the "Minimum C Project Files for CMake" section. 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. 3. See the appendix at the bottom of this file for an example of using a ctest script for building and testing. See INSTALL_CMake.txt for more information. ======================================================================== 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 3.10.1. 2. You have installed the HDF5 library built with CMake, by executing the HDF Install Utility (the *.msi 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) 5. Created a CMakeLists.txt file(s) for your source. See Section III below. ======================================================================== II. Building HDF5 Applications with CMake ======================================================================== Go through these steps to build HDF5 applications with CMake. (The application must support building with CMake.) 1. Run CMake 2. Configure the cache settings 3. Build HDF5 Applications 4. Test HDF5 Applications 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 * MinGW Makefiles * NMake Makefiles * Unix Makefiles * Visual Studio 12 2013 * Visual Studio 12 2013 Win64 * Visual Studio 14 2015 * Visual Studio 14 2015 Win64 * Visual Studio 15 2017 * Visual Studio 15 2017 Win64 is: * BUILD_TESTING:BOOL=ON * BUILD_SHARED_LIBS: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 12 2013). 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 12 2013" -DBUILD_TESTING:BOOL=ON .. 3. Build HDF5 Applications 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 Applications 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. Minimum C Project Files for CMake ======================================================================== Given the preconditions in section I, create a CMakeLists.txt file at the source root. Include the following text in the file: ########################################################## cmake_minimum_required (VERSION 3.10) project (HDF5MyApp C CXX) set (LIB_TYPE STATIC) # or SHARED string(TOLOWER ${LIB_TYPE} SEARCH_TYPE) find_package (HDF5 NAMES hdf5 COMPONENTS C ${SEARCH_TYPE}) # find_package (HDF5) # Find non-cmake built HDF5 INCLUDE_DIRECTORIES (${HDF5_INCLUDE_DIR}) set (LINK_LIBS ${LINK_LIBS} ${HDF5_C_${LIB_TYPE}_LIBRARY}) set (example hdf_example) add_executable (${example} ${PROJECT_SOURCE_DIR}/${example}.c) TARGET_C_PROPERTIES (${example} ${LIB_TYPE} " " " ") target_link_libraries (${example} ${LINK_LIBS}) enable_testing () include (CTest) add_test (NAME test_example COMMAND ${example}) ########################################################## ======================================================================== IV. APPENDIX ======================================================================== Below is an example of a ctest script that can be used to build the examples. Adjust the values as necessary. Note that the defaults can be entered on the command line and the build folder is created as a sub-folder. Windows should adjust the forward slash to double backslashes, except for the HDF_DIR environment variable. NOTE: this file is available at the HDF web site: https://portal.hdfgroup.org/display/support/Building+HDF5+with+CMake HDF518_Examples.cmake HDF5_Examples_options.cmake Also available at the HDF web site is a CMake application framework template. You can quickly add files to the framework and execute the script to compile your application with an installed HDF5 binary. ======================================================================== ctest use of HDF518_Examples.cmake and HDF5_Examples_options.cmake ======================================================================== cmake_minimum_required (VERSION 3.10) ############################################################################################################### # This script will build and run the examples from a folder # Execute from a command line: # ctest -S HDF518_Examples.cmake,OPTION=VALUE -C Release -V -O test.log ############################################################################################################### set(CTEST_CMAKE_GENERATOR "@CMAKE_GENERATOR@") if("@CMAKE_GENERATOR_TOOLSET@") set(CMAKE_GENERATOR_TOOLSET "@CMAKE_GENERATOR_TOOLSET@") endif() set(CTEST_DASHBOARD_ROOT ${CTEST_SCRIPT_DIRECTORY}) # handle input parameters to script. #INSTALLDIR - HDF5 root folder #CTEST_CONFIGURATION_TYPE - Release, Debug, RelWithDebInfo #CTEST_SOURCE_NAME - name of source folder; HDF5Examples if(DEFINED CTEST_SCRIPT_ARG) # transform ctest script arguments of the form # script.ctest,var1=value1,var2=value2 # to variables with the respective names set to the respective values string(REPLACE "," ";" script_args "${CTEST_SCRIPT_ARG}") foreach(current_var ${script_args}) if("${current_var}" MATCHES "^([^=]+)=(.+)$") set("${CMAKE_MATCH_1}" "${CMAKE_MATCH_2}") endif() endforeach() endif() ################################################################### ### Following Line is one of [Release, RelWithDebInfo, Debug] ##### set(CTEST_CONFIGURATION_TYPE "$ENV{CMAKE_CONFIG_TYPE}") if(NOT DEFINED CTEST_CONFIGURATION_TYPE) set(CTEST_CONFIGURATION_TYPE "Release") endif() set(ADD_BUILD_OPTIONS "${ADD_BUILD_OPTIONS} -DCTEST_CONFIGURATION_TYPE:STRING=${CTEST_CONFIGURATION_TYPE}") ################################################################## if(NOT DEFINED INSTALLDIR) set(INSTALLDIR "@CMAKE_INSTALL_PREFIX@") endif() if(NOT DEFINED CTEST_SOURCE_NAME) set(CTEST_SOURCE_NAME "HDF5Examples") endif() if(NOT DEFINED HDF_LOCAL) set(CDASH_LOCAL "NO") else() set(CDASH_LOCAL "YES") endif() if(NOT DEFINED CTEST_SITE) set(CTEST_SITE "local") endif() if(NOT DEFINED CTEST_BUILD_NAME) set(CTEST_BUILD_NAME "examples") endif() set(ADD_BUILD_OPTIONS "${ADD_BUILD_OPTIONS} -DSITE:STRING=${CTEST_SITE} -DBUILDNAME:STRING=${CTEST_BUILD_NAME}") #TAR_SOURCE - name of tarfile #if (NOT DEFINED TAR_SOURCE) # set (CTEST_USE_TAR_SOURCE "HDF5Examples-1.10.1-Source") #endif () ############################################################################################################### if(WIN32) set(SITE_OS_NAME "Windows") set(ENV{HDF5_DIR} "${INSTALLDIR}/cmake") set(CTEST_BINARY_NAME ${CTEST_SOURCE_NAME}\\build) set(CTEST_SOURCE_DIRECTORY "${CTEST_DASHBOARD_ROOT}\\${CTEST_SOURCE_NAME}") set(CTEST_BINARY_DIRECTORY "${CTEST_DASHBOARD_ROOT}\\${CTEST_BINARY_NAME}") else() set(ENV{HDF5_DIR} "${INSTALLDIR}/share/cmake") set(ENV{LD_LIBRARY_PATH} "${INSTALLDIR}/lib") set(CTEST_BINARY_NAME ${CTEST_SOURCE_NAME}/build) set(CTEST_SOURCE_DIRECTORY "${CTEST_DASHBOARD_ROOT}/${CTEST_SOURCE_NAME}") set(CTEST_BINARY_DIRECTORY "${CTEST_DASHBOARD_ROOT}/${CTEST_BINARY_NAME}") endif() if(${CDASH_LOCAL}) set(ADD_BUILD_OPTIONS "${ADD_BUILD_OPTIONS} -DCDASH_LOCAL:BOOL=ON") endif() set(ADD_BUILD_OPTIONS "${ADD_BUILD_OPTIONS} -DHDF5_PACKAGE_NAME:STRING=@HDF5_PACKAGE@@HDF_PACKAGE_EXT@") ############################################################################################################### # For any comments please contact help@hdfgroup.org # ############################################################################################################### ############################################################################################# #### Change default configuration of options in config/cmake/cacheinit.cmake file ### #### format for file: set(ADD_BUILD_OPTIONS "${ADD_BUILD_OPTIONS} -DXXX:YY=ZZZZ") ### ############################################################################################# if(WIN32) include(${CTEST_SCRIPT_DIRECTORY}\\HDF5_Examples_options.cmake) else() include(${CTEST_SCRIPT_DIRECTORY}/HDF5_Examples_options.cmake) endif() #----------------------------------------------------------------------------- set (CTEST_CMAKE_COMMAND "\"${CMAKE_COMMAND}\"") ## -------------------------- if (CTEST_USE_TAR_SOURCE) ## Uncompress source if tar or zip file provided ## -------------------------- if (WIN32) message (STATUS "extracting...
