You'll only be asked to choose a compiler the first time you run helloworld.cpp. Press the play button in the top right corner of the editor.Ĭhoose C/C++: cl.exe build and debug active file from the list of detected compilers on your system. Open helloworld.cpp so that it is the active file. Make sure you have a C++ compiler installed before attempting to run and debug helloworld.cpp in VS Code. Remember, the C++ extension uses the C++ compiler you have installed on your machine to build your program. You can press the Tab key to insert the selected member then, when you add the opening parenthesis, you will see information about any arguments that the function requires. You should immediately see a completion list that shows all the member functions, and a window that shows the type information for the msg object: as you would when calling a member function. After the declaration of the msg variable, start typing msg. In your new helloworld.cpp file, hover over vector or string to see type information. You can ignore this notification by selecting the X ( Clear Notification). Note: When you save or open a C++ file, you may see a notification from the C/C++ extension about the availability of an Insiders version, which lets you test new features and fixes. You can find out more about the other views in the VS Code User Interface documentation. You'll look at the Run view later in this tutorial. The Activity Bar on the far left lets you open different views such as Search, Source Control, and Run. You can also enable Auto Save to automatically save your file changes, by checking Auto Save in the main File menu. Notice how the file you just added appears in the File Explorer view ( ⇧⌘E (Windows, Linux Ctrl+Shift+E)) in the side bar of VS Code: Now press ⌘S (Windows, Linux Ctrl+S) to save the file. If the Developer Command Prompt is using the BuildTools location as the starting directory (you wouldn't want to put projects there), navigate to your user folder ( C:\users\ You can test that you have the C++ compiler, cl.exe, installed correctly by typing 'cl' and you should see a copyright message with the version and basic usage description. The exact name depends on which version of Visual Studio or the Visual Studio Build Tools you have installed. To open the Developer Command Prompt for VS, start typing 'developer' in the Windows Start menu, and you should see it appear in the list of suggestions. An ordinary shell such as PowerShell, Bash, or the Windows command prompt does not have the necessary path environment variables set. To use MSVC from a command line or VS Code, you must run from a Developer Command Prompt for Visual Studio. Check your Microsoft Visual C++ installation Note: You can use the C++ toolset from Visual Studio Build Tools along with Visual Studio Code to compile, build, and verify any C++ codebase as long as you also have a valid Visual Studio license (either Community, Pro, or Enterprise) that you are actively using to develop that C++ codebase. Check the Desktop development with C++ workload and select Install. This will launch the Visual Studio Installer, which will bring up a dialog showing the available Visual Studio Build Tools workloads. From the Visual Studio Downloads page, scroll down until you see Tools for Visual Studio under the All Downloads section and select the download for Build Tools for Visual Studio 2022. You can also install the Desktop development with C++ workload without a full Visual Studio IDE installation. If it's not installed, then check the box and select the Modify button in the installer. If you have a recent version of Visual Studio, open the Visual Studio Installer from the Windows Start menu and verify that the C++ workload is checked. Install the Microsoft Visual C++ (MSVC) compiler toolset. You can install the C/C++ extension by searching for 'c++' in the Extensions view ( ⇧⌘X (Windows, Linux Ctrl+Shift+X)). To successfully complete this tutorial, you must do the following: If you have any problems, feel free to file an issue for this tutorial in the VS Code documentation repository. For those subjects, there are many good resources available on the Web. This tutorial does not teach you details about the Microsoft C++ toolset or the C++ language. In this tutorial, you configure Visual Studio Code to use the Microsoft Visual C++ compiler and debugger on Windows.Īfter configuring VS Code, you will compile and debug a simple Hello World program in VS Code. Configure IntelliSense for cross-compiling.
