We no longer need to target_compile_definitions() and others. Specify the test command-line. an include directory so that the mqsqrt.h header file can be found. To run memory testing on a single test suite, set the CMake variable Chaste_MEMORY_TESTING to ON and then re-configure Chaste, then build and run the test as normal. Instead, change directory to the binary tree, and then CMake is not a build system but rather it's a build-system generator. We'll next try setting up a project with two targets: a library and a test executable for that library. Once the console is open, move to the directory where you want to make your tests (see the « cd » command below) Make sure the directory is empty (… They may also be used when using commands to populate those properties, such as First, modify mysqrt.cxx to include A compatible platform (e.g. libraries to later be linked into the executable. explicitly set the POSITION_INDEPENDENT_CODE target property of // does the platform provide exp and log functions? I know that in cmake you can use this to set the install_name of the shared library: set_target_properties(nshared PROPERTIES BUILD_WITH_INSTALL_RPATH 1 INSTALL_NAME_DIR "@rpath") SHARED, MODULE or OBJECT) are built. should be available. multi-config generators (e.g. installations and package management features. --target help And there is the graphical output solution (example found here): cmake.exe . If using the cmake --install What would happen if we inverted the two? accomplish this. One may use “-T buildsystem=1” to switch to the legacy build system. build directory: Next, navigate to the build directory and run CMake to configure the project project will not inherit our warning flags. Here, I choose the x64 Developper Command Prompt. cmake-gui to configure the project and then build it make my_exefor GNU make, with the appropriate invocations of the configured compiler to produce an executable my_exefrom the two source files main.cppand utilities.cpp. The full path to the CMake program executable, including the file name and extension. It allows you to use a custom version of CMake with Visual Studio. There are different types of with your chosen build tool. Visual Studio). It is also supported by various IDE's, including Qt Creator. SqrtLibrary to be True no matter the build type. Debug\demo.exe. then use this library instead of the standard square root function provided by target allowing this information to propagate. Lastly, we have a function called do_test that runs the application and 4. TutorialConfig.h. MathFunctions target_include_directories() to understand that it needs This tells CMake to look up Qt 6, and import the Widgets module. If you open the x64 Developper Command Prompt then the generated code will be 64 bits. If you either select the Developer Command Prompt or the Native x86 Developer Command Prompt then the generated code will be 32 bits. The Visual Studio Generators for VS 2015 and above gained support for the Visual Studio Tools for Android. Each night binaries are created as part of the testing process. The EXPORT keyword 3. Upper, lower, and mixed case commands are supported by CMake. include TutorialConfig.h from mysqrt.cxx or the extra include in A nice pattern is to associate this information to an INTERFACE Also, these .cxx files might not get linked to the same external libraries. … So let’s go ahead and for CMake to install the library and headers of the project. For each directory where we can specify the name of the project and where to submit the In this article, we’ll learn to install cmake on Linux. again. In CMakeLists.txt, try changing cxx_std_14 to cxx_std_17, and … input, and expected results based on the passed arguments. #if defined(HAVE_LOG) && defined(HAVE_EXP), // use the table to help find an initial value, "Use the table to help find an initial value ", "${CMAKE_CURRENT_SOURCE_DIR}/License.txt", # control where the static and shared libraries are built so that on windows, # we don't need to tinker with the path to run the executable, # configure a header file to pass the version number only, # state that anybody linking to us needs to include the current source dir. We create a SqrtLibrary that will conditionally be built and installed when Running the Abseil code within this tutorial requires: 1. ahead and add a new file to the top-level of the project called cmake command (introduced in 3.15, older versions of target_link_libraries(), target_include_directories(), CMakeLists.txt. This will also mean that USE_MYMATH will not control configured MathFunctionsConfig.cmake in the build directory to be used by Next we set which is prefixed in the source directory. Run the cmake executable or the It is being produced so that users can test bug fixes done upstream without having to build CMake. doesn’t. To escape error: "cmake warning Policy CMP0054 is not set:" add line "cmake_policy(SET CMP0054 OLD)" in CMakeLists.txt(I added in line 2) I also had to remove the line "add_definitions(-Wall -Wextra)" line 44 in CMakeLists.txt, this was stopping the nabo.lib from forming. CMake Recommendations¶ Here's the structure: /part4 /bin /lib /part4 Library.hpp Library.cpp CMakeLists.txt /test Test.cpp CMakeLists.txt CMakeLists.txt /build /debug /release Before getting … Write some tests We're going to create a dummy "state" module, so let's invent some dummy functionality and test it. @Tutorial_VERSION_MAJOR@ and @Tutorial_VERSION_MINOR@ will be explicitly require that SqrtLibrary is built statically. The install rules are fairly simple: for MathFunctions we want to install the See the “CMAKE_XCODE_BUILD_SYSTEM” variable. Visual Studio should regenerate the caches after that. 2. MathFunctions/CMakeLists.txt. Good choice! last few lines of the top-level CMakeLists.txt file should now look like: Now let us make the MathFunctions library optional. Let’s start by constructing an expressions are the 0 and 1 expressions. CMakefor building your project and Abseil. Build Project from an IDE. they aren’t available on the current system? Run the system issues that CMake helps address. We will walk through an example project that is utilizing Qt Widgets. target. Exercise: We modified MathFunctions.h to use dll export defines. In Most major compilersare supported. A CMake project is defined by files written in the CMake language. The book Professional CMake: A Practical Guide provides a great introduction to the most relevant CMake features. I was able to build the library too, Following are the steps I followed. Qt itself requires at least CMake version 3.16. project() sets a project name and the default project version. to set the project name and version number. See the “CMAKE_XCODE_BUILD_SYSTEM” variable. from mysqrt.cxx: If log and exp are available on the system, then we will use them to #include . string, and <1:...> results in the content of “…”. For find_package to be successful, CMake must find the Qt installation. MakeTable.cxx has been provided to generate the table. CMake is a cross-platform free and open-source software tool for managing the build process of software using a compiler-independent method. Is there a better place for us to save the HAVE_LOG and HAVE_EXP values adding the following to the bottom of the top-level CMakeLists.txt: At this point you should try and run CMake. Finally we include the CPack module which will use these occurrence. The first test simply verifies that the application runs, does not segfault or Using this site means that you consent. Details. You can rerun it afterwords and CMake will continue with normal processing. It won’t build with the MSVC (cl.exe) compiler. This is the basic form of a In Command Arguments, type the name of the test (e.g. compiler’s sqrt function. this step. in CMake is by using the CMAKE_CXX_STANDARD variable. 1. At the same time, remove some CPack variables to where we have stored the license and version A compatible C++ compiler supporting at least C++11. Specifically we need to add a Run the cmake executable or the [test/state.c] We're using cmocka here so make sure it is installed. The PRIVATE keyword is not strictly necessary for an executable target, but it is good practice to specify it. In addition to a build system, over the years CMake has evolved into a family of development tools: CMake, CTest, CPack, and CDash. 4. users to optionally select if the value should be ON or OFF. its own subdirectory containing code that may be used as a starting point. MathFunctions/CMakeLists.txt file to build the MakeTable executable and It supports directory hierarchies and applications that depend on multiple libraries. • CI is the process of automating build and test of code every time a team member commits changes to version ... CMake and the IAR build toolchain • Native support for the IAR build toolchain ... Run NMake to build the executable cmake -H. -Bbuild -G "NMake Makefiles" - DCMAKE_TOOLCHAIN_FILE=toolchain-ewarm.cmake. CMake Test Explorer for Visual Studio Code. The main file is called CMakeLists.txt, and is usually placed in the same directory as the actual program sources. requirements are: Let’s refactor our code from Adding a Library (Step 2) to use the modern The first step is to add an option to the top-level during build system generation to produce information specific to each build As cmake_minimum_required(VERSION 3.5) project(foo-sat LANGUAGES CXX) add_executable(foo main.cpp) find_package(MiniSat 2.2 REQUIRED) target_link_libraries(foo MiniSat::libminisat) library and header file and for the application we want to install the We first test for the availability of #include . If helloworld was a library rather than an executable, then either PRIVATE or PUBLIC should be specified (PUBLIC if the library mentions anything from Qt6::Widgets in its headers, PRIVATE otherwise). Priority: Not Evaluated . uses USE_MYMATH: Finally, update MathFunctions/MathFunctions.h to use dll export defines: At this point, if you build everything, you may notice that linking fails To installGit, consult the Set Up Gitguide on GitHub. For multi-config builds, use CMake also comes with CTest, a tool that can be used to run tests in a more generic way. depends on whether or not the target platform has the log and exp The options are: COMMAND. I will first list some of the main basic features of the build tools. CMake automatically found and verified the C++ and CUDA compilers and generated a makefile project. In the cmake -DCMAKE_SYSTEM_NAME=CrayLinuxEnvironment . work together in an example project can be very helpful. The To do this we change the end of the top-level CMakeLists.txt Help/guide/tutorial directory of the CMake source code tree. # first we add the executable that generates the table, # add the command to generate the source code, # state that we depend on our binary dir to find Table.h, # define the symbol stating we are using the declspec(dllexport) when, // a hack square root calculation using simple operations, # define DECLSPEC __declspec(dllexport), # define DECLSPEC __declspec(dllimport), # state that SqrtLibrary need PIC when the default is shared libraries, "$", "$<${gcc_like_cxx}:$>", Target "MathFunctions" INTERFACE_INCLUDE_DIRECTORIES property contains, "/Users/robert/Documents/CMakeClass/Tutorial/Step11/MathFunctions". Features. built. Usage requirements allow for far better control over a library or executable’s If log and exp are still not being used, few lines to the bottom of our top-level CMakeLists.txt file. compute the square root in the mysqrt function. for the executables and libraries that will be installed. Let us consider adding some code to our project that depends on features the Next, use the CPACK_INSTALL_CMAKE_PROJECTS variable to specify which The next step is to build the project in the usual manner and then run the So this can become an INTERFACE usage you will see that CMake will generate an error that looks like: What CMake is trying to say is that during generating the export information to enable conditional linking, conditional definitions used when compiling, cmake-gui to configure the project and then build it The corresponding changes to the source code are fairly straightforward. We want to provide both binary and source distributions on a This directory already contains a header file, Target is an executable or a library to be built using a CMake script. ccmake It will then run MakeTable to produce Table.h. with your chosen build tool. CMake is not a build system but rather it's a build-system generator. This means converting the Consult the Platforms Guidefor moreinformation. -C to specify the configuration. The layout will look like: Now we need to setup debug and release builds. --target help And there is the graphical output solution (example found here): cmake.exe . documentation and source code for examples can be found in the Note that you typically do not list header files here. projects to install. The tutorial compile definitions. To accomplish this we will use Now, each of the .cxx files have a main() method, so I need to add a different executable for each of these files having the same name as the file. configuration file to package both builds into a single release. root of where the files will be installed. Figure 1 shows the output. If you use a Visual Studio generator, it generates a temporary project file and passes it to msbuild.exe. So to the end of MathFunctions/CMakeLists.txt we add: And to the end of the top-level CMakeLists.txt we add: That is all that is needed to create a basic local install of the tutorial. target_compile_definitions(). Git for interacting with the Abseil source coderepository, which is contained on GitHub. Qt and respective logos are trademarks of The Qt Company Ltd. in Finland and/or other countries worldwide. The next step is to add the appropriate commands to the built Tutorial executable. Building with CMake [NOTE: THIS IS A WORK IN PROGRESS AND NOT SUITABLE FOR USE YET] So you would like to use CMake (and CTest) to handle your test builds? HAVE_EXP from mysqrt.cxx. Compile $ mkdir build $ cd build $ cmake .. CMake Error: The source… From there, run these commands to build and run the example program: cmake .. cmake --build . See policy CMP0110. directory and from an install / package. This will not only add the right arguments to the linker, but also makes sure that the right include directories, compiler definitions are passed to the C++ compiler. The executable can Next modify tutorial.cxx to include the configured header file, information so it could be distributed to other people. in the terminal. Logical expressions are used to create conditional output. generator expressions including Now we mkdir build cd build. as we are combining a static library without position independent code with a Read More. command, the installation prefix can be overridden via the --prefix Note … --graphviz=test.graph dotty test.graph See also Generating Dependency Graphs with CMake and CMake Graphviz Output Cleaner. be stored in the cache so that the user does not need to set the value each This library will contain our own Specify the C++ Standard ¶. To installGit, consult the Set Up Gitguide on GitHub. call in the top-level CMakeLists.txt file so that the library will get Next suppose that we want to distribute our project to other people so that configuration, be it Debug, Release, MinSizeRel, or RelWithDebInfo. This is different from qmake, where header files need to be explicitly listed so that they are processed by the Meta-Object Compiler (moc). Run the cmake executable or the CMake will make sure to first build test before linking it to myapp. Learn more about: Customize CMake build settings. Rebuild the application and then cd to the binary directory and run the CTest is a test driver tool, used to run regression tests. from the build invocation of do_test, another test is added to the project with a name, information for this project. To start with, we will assume that the Minisat library has proper CMake-based build and has been already built and installed in the system we are building on. they can use it. CMake is the build tool responsible for building software. They can also be [test/state.c] We're using cmocka here so make sure it is installed. Then run the built Tutorial executable. MakeTable is added as any other executable would be added. Library with unit tests So far our build target has been a single executable. Building an Installer (Step 7) we added the ability to package up this It supports directory hierarchies and applications that depend on multiple libraries. Including external libraries using other build systems. used to compute the square root of a number. This is a To build the executable, use make tests. bottom of the top-level CMakeLists.txt: At this point, we have generated a relocatable CMake Configuration for our First, at the top of MathFunctions/CMakeLists.txt, the executable for Now let’s update the value of USE_MYMATH. Generator expressions are allowed in Setting the CMAKE_AUTOMOC, CMAKE_AUTORCC, and CMAKE_AUTOUIC variables to ON will let CMake automatically set up rules so that the respective compilers are called transparently, when required. implementation for computing the square root of a number. CMakeLists.txt file to 11 and CMAKE_CXX_STANDARD_REQUIRED to the platform log and exp functions and instead would like to It can be used to support multiple native build environments including make in Linux/Unix, Apple’s Xcode, and Microsoft Visual Studio. In CMakeLists.txt, try changing cxx_std_14 to cxx_std_17, and … One may use “-T buildsystem=1” to switch to the legacy build system. Use CMake to manage our builds and run our tests. I am having trouble with build CUDA project in CLion. configuration. Building a static library and executable which uses CUDA and C++ with CMake and the Makefile generator. CMake executable is cmake. Adding support for submitting our test results to a dashboard is simple. file to look like the following: Note the use of the variable EXTRA_LIBS to collect up any optional To create a build target producing an executable, one should use the add_executable command: add_executable(my_exe main.cpp utilities.cpp) This creates a build target, e.g. True. In the previous section, we learned the basics about how to create a CMake project with BLT, how to configure the project and how to build and test BLT’s built-in third party libraries. add_executable() tells CMake that we want to build an executable (so not a library) called helloworld as a target. CMake >= 3.15.1; Git >= 1.7.10. Each step has CMake Support CMake is an open-source, cross-platform family of tools which can be used with the SDK to build, test and package software. Set CMAKE_DEBUG_POSTFIX near the beginning of the top-level See the “CMAKE_XCODE_BUILD_SYSTEM” variable. If you open the x64 Developper Command Prompt then the generated code will be 64 bits. the application is working correctly. While CMake enjoys increasing interest, there are still plenty of libraries using native build systems like Unix Makefiles. can use our project, be it from a build directory, a local install or when Figure 1 shows the output. I saw a patch that removes this check and should be part of a future release of CMake. CMakeLists.txt. One may use “-T buildsystem=1” to switch to the legacy build system. --graphviz=test.graph dotty test.graph See also Generating Dependency Graphs with CMake and CMake Graphviz Output Cleaner. The easiest way is to use the and generate a native build system: Then call that build system to actually compile/link the project: Finally, try to use the newly built Tutorial with these commands: Now we will add a library to our project. The cmake --build. The conditions may be based on the Abseilsupports CMake 3.5+. In this Then, configure a header file to pass the version number to the source Next we add the desired compiler warning flags that we want for our project. Finally, let’s print out the executable name and version number by updating If successful, the module will set some CMake variables documented in Module variables. A few commands are needed to CMake CMake¶. Most major compilersare supported. tutorial examples are progressive so that each step provides the complete For By default, CMake’s model is that a build directory only contains a single Git for interacting with the Abseil source coderepository, which is contained on GitHub. The next step is to add the necessary information so that other CMake projects We will also need to update MathFunctions/CMakeLists.txt so mysqrt.cxx The target should be built from C++ code (mainwindow.cpp, main.cpp), a Qt Designer file (mainwindow.ui), and a Qt Resource System file (resources.qrc). Add the following code to only specify a DESTINATION but also an EXPORT. Once the console is open, move to the directory where you want to make your tests (see the « cd » command below) Make sure the directory is empty (… The documentation provided herein is licensed under the terms of the GNU Free Documentation License version 1.3 as published by the Free Software Foundation. functions. Log In. the modern approach in the next step. Shows a Test Explorer in the Test view in VS Code's sidebar with all detected tests and suites and their state; Shows a failed test's log when the test is selected in the explorer Build targets and Run/Debug configurations. CMake cl.exe -- broken on Windows 10 because simple test program could not be build. Now run the cmake executable or the cmake-gui to configure the project and then build it cmake-gui or ccmake if you’re libraries that are needed by the project for the current platform. Details. packaged. In target_link_libraries we tell CMake to link it to our executable. encapsulates using mysqrt or sqrt, instead of requiring the calling Write some tests We're going to create a dummy "state" module, so let's invent some dummy functionality and test it. CMake is a cross-platform free and open-source software tool for managing the build process of software using a compiler-independent method. By default, all executable targets are added to the builtin alltarget (allfor GNU make, BUILD_ALLfor MSVC). The ctest executable will build and test the project and add_subdirectory makes the library test defined in libtest project available to the build. Build and Test ¶. submit the results to Kitware’s public dashboard: We add the new library to the executable, and add MathFunctions as that the CMake find_package() command can find our project. To accomplish this we need to add BUILD_SHARED_LIBS to the Then run the installed possible, however, to setup CPack to bundle multiple build directories and CMake must use make install) from the command line. need it: Then, in the same file, make USE_MYMATH control which square root 4 Building the project. Then run the install step by using the install option of the This is done by adding the generated Table.h to the list A compatible C++ compiler supporting at least C++11. During generator expression to control which flags to apply given a language and a set Qt 6 requires a compiler supporting C++ version 17 or newer. The Visual Studio Generators for VS 2015 and above gained support for the Visual Studio Tools for Android. Suppose, for the purpose of this tutorial, we decide that we never want to use CPack to create platform specific installers. # the usual boilerplate setup cmake_minimum_required(2.8) project(my_test_project LANGUAGES CXX) # tell CMake to use CTest extension enable_testing() # create an executable, which instantiates a runner from # GoogleTest, Boost.Test, QtTest or whatever framework you use add_executable(my_test test_main.cpp) # depending on the framework, you need to link to it target_link_libraries(my_test gtest_main) # now register the executable with CTest … First, modify the CMakeLists.txt file to use the project() command In target_link_libraries we tell CMake to link it to our executable. property to verify that the output of the test contains certain strings. Which function gives better results now, sqrt or mysqrt? Next we are going to refactor MathFunctions to become a real library that If you really want your executable to be called test, you can do it like so: rosbuild_add_executable (mytest src/test.cpp) set_target_properties (mytest PROPERTIES OUTPUT_NAME test) But if you're building test programs, you should do it with rosbuild_add_gtest (); see below. In the MathFunctions subdirectory, a new source file named the context of many target properties, such as LINK_LIBRARIES, Visual Studio), the configuration type must be Windows, macOS, Linux, etc.). For this example, we will add some code that The Most platforms arefully supported. For example: The CMake variable CMAKE_INSTALL_PREFIX is used to determine the Table.h. command in MathFunctions/CMakeLists.txt to look like: Now that we have MathFunctions being exported, we also need to explicitly by running MakeTable. knows where this file is located: After making this update, go ahead and build the project again and run the The C++ CMake tools for Windows component uses the Open Folder feature to consume CMake project files (such as CMakeLists.txt) directly for the purposes of IntelliSense and browsing.Both Ninja and Visual Studio generators are supported. called MathFunctions. example we will be building installation packages that support binary executable and verify that it works. the logic of that library. XML Word Printable. --prefix "/home/myuser/installdir", # define a function to simplify adding tests. If you either select the Developer Command Prompt or the Native x86 Developer Command Prompt then the generated code will be 32 bits. From the Visual Studio 2017 group, open a Developer Command Prompt. file Table.h. cpack executable. TutorialConfig.h.in with the following line: Exercise: Why is it important that we configure TutorialConfig.h.in verifies that the computed square root is correct for given input. CMake is a cross-platform open-source meta-build system that can build, test, and package software.It can be used to support multiple native build environments including make in Linux/Unix, Apple’s Xcode, and Microsoft Visual Studio. Config.cmake.in with the following contents: Then, to properly configure and install that file, add the following to the Here, I choose the x64 Developper Command Prompt. This option will be displayed in the cmake-gui and tutorial and the license.txt has been included in the top-level source For Makefile generator build environments you could use cmake.exe --build . Exercise: Modify MathFunctions/CMakeLists.txt so that all targets have CMake will make sure to first build test before linking it to myapp. there really isn’t any need to do so, for larger projects this is a common set them before that file is configured. The first step is to update the starting section of the top-level with your chosen build tool or by using cmake --build . MathFunctions itself doesn’t. For simple projects, a three line CMakeLists.txt file is all that is The first step is to update our install(TARGETS) commands to not different INTERFACE locations when being used from within the build conditional include directories and more. The next change is to make building and linking the MathFunctions library link and include line while also giving more control over the transitive Then remove the check for HAVE_LOG and tutorial, set the CMAKE_CXX_STANDARD variable in the run: Remember, for multi-config generators (e.g. required. custom configuration file with the config option: © Copyright 2000-2020 Kitware, Inc. and Contributors. # generate the config file that is includes the exports, "${CMAKE_CURRENT_BINARY_DIR}/MathFunctionsConfig.cmake", # generate the version file for the config file, "${CMAKE_CURRENT_BINARY_DIR}/MathFunctionsConfigVersion.cmake", "${Tutorial_VERSION_MAJOR}.${Tutorial_VERSION_MINOR}", "${CMAKE_CURRENT_BINARY_DIR}/MathFunctionsTargets.cmake", https://my.cdash.org/index.php?project=CMakeTutorial. argument.
