![]() ![]() On the Visual Studio downloads page, move down into the All Downloads section. Don’t worry, we aren’t installing Visual Studio, just the build tools. We need the build tools provided by Visual Studio. Click on the Install button to install it. This extension provides Intellisense, debugging, and browsing capabilities. A number of C and C++ extensions are displayed. Start VS Code and display the extensions panel (select View → Extensions from the main menu). When it is completed, run the downloaded file. Select the appropriate version click on the Windows button for the 圆4 version, or one of the ARM links for ARM if that is applicable to you. On Windows, the latest version of Visual Studio Code is available on its download page. Installing Visual Studio Code and Extensions In a later article, I will discuss using the gnu tools on Linux (Ubuntu). I will start the project on Windows using VS Code and the Visual Studio Build Tools, but if you wish, you can start with a different IDE, or even a different operating system. Just about any tool that can be downloaded from the internet, and which provides CMake files for building, can be used. I will show one example of this when I use Google Test in this project. With CMake, you can download, build, and use a large number of tools. You will see this when I port my project from Windows using the Visual Studio build tools to Linux using the gnu build tools. Aside from specifying the tools to use, no other changes are required to the CMake specification files. You can specify the build tools that you want to use for example, you can use MSVC or LLVM on Windows, and gnu or LLVM on Unix-like systems, including Linux, OSX, and MSYS or MinGW. Because it can be called from the command line, it integrates well with continuous integration/continuous build systems. It can even create make files if you want to do everything from the command line. Similar capabilities are available for every other popular IDE. For example, CMake can generate solution (.sln) and project files (.vcxproj) that Visual Studio and Visual Studio Code use on Windows. CMake then takes that information and generates the files needed to build the system. You specify what you want done, not how to do it. Why Use CMake?ĬMake is a powerful and robust build system. Most of the information is applicable to using almost any IDE, or indeed, no IDE at all. I will also use git and Google Test, and port the project from Windows to Linux. Queue.In this article and several more, I will be discussing developing a very simple C++ library and application using CMake and Visual Studio Code. The add_executable directive tells CMake which source files to use to build the simple application.Īn example simple.cpp that works with the above CMakeLists.txt is: #include The IntelDPCPP module sets the compiler and linker flags required to build a project with DPC++. IntelDPCPP is in CMake's search path after running setvars.sh on Linux or setvars.bat on Windows. The find_package directive, tells CMake to use the IntelDPCPP module distributed with the oneAPI distribution. Projects that also use C, Fortran, or other languages can list the languages used them in the LANGUAGES parameter.Īpplications not using pre-compiled header files might work with CMake 3.21.0 on Windows. The project CMake directive tells CMake the name of this project and that it uses C++. For Windows the minimum required version is 3.23.0. The minimum required CMake version for Linux is 3.20.5. # CMake 3.20.5 is the minimum recommended for IntelLLVM on Linux # need at least CMake 3.23 for IntelLLVM support of IntelDPCPP package on Windows The following CMakeLists.txt builds the DPC++ application in simple.cpp for either Windows or Linux with the minimum supported CMake version for each platform. Refer to the package for more information.ĬMake is supported on the Windows and Linux command line. ![]() ![]() The heterogeneous compilation configuration package exposes other variables that may be required.Run CMake and build your applications as normal.See the Linux and Windows sections above for specific settings. Select the appropriate compilers for C or C++.The package directory is found in the parent directory of the icx bin directory. The heterogeneous compilation configuration package ( IntelDPCPPConfig.cmake) is shipped with the compiler. Add the following snippets to your project’s CMakeLists.txt:.Use the following steps to enable the compiler for your project: ![]()
