See Get Started with C++ and Mingw-w64 in Visual Studio Code. How do I get the new IntelliSense to work with MinGW on Windows? The easiest way to fix this is to set compilerPath in c_cpp_properties.json to the path to your compiler. The most common reason for this is missing include paths and defines. Why do I see red squiggles under Standard Library types? If this is undesirable, you can open your c_cpp_properties.json file and change it. When you open a workspace for the first time, the extension adds $/** to the includePath and the browse.path is left undefined (so it defaults to the includePath). To disable recursive enumeration of a path, you can append a /* to the path string. This engine will recursively enumerate all files under the paths specified and track them as potential includes while tag parsing your project folder. This array of path strings is used by the "Tag Parser" ("browse engine"), which populates a database with global symbol information. These paths are not searched recursively unless they end with /**. When your source files are parsed, the IntelliSense engine will prepend these paths to the files specified by your #include directives while attempting to resolve them. The include paths are the same paths that you would send to your compiler via the -I switch. This array of path strings is used by the "Default" IntelliSense engine, which provides semantic-aware IntelliSense features. These two settings are available in c_cpp_properties.json and can be confusing. What is the difference between includePath and browse.path? If you want to show the linting information anyway, you can change the value of the C_Cpp.errorSquiggles setting. If you check the Problems window in VS Code, the extension will provide more information about which files it was unable to locate. Note: If the extension is unable to resolve any of the #include directives in your source code, it will not show linting information for the body of the source file. In the "Advanced" section of the Configuration UI, you can supply the path to your compile_commands.json and the extension will use the compilation information listed in that file to configure IntelliSense. command to enable any such extension to provide the configurations for IntelliSense.Ī third option for projects without build system extension support is to use a compile_commands.json file if your build system supports generating this file. Use the C/C++: Change Configuration Provider. For example, the CMake Tools extension can configure projects that use the CMake build system. Or, if you install a build system extension that interfaces with our extension, you can allow that extension to provide the configurations for you. In that view, you can change the compiler you want to emulate, the paths to include files you want to use, preprocessor definitions, and more. If this automatic configuration is insufficient, you can modify the defaults by running the C/C++: Edit Configurations (UI) command. (for example, cl.exe/MinGW for Windows, gcc/clang for macOS/Linux). Without any configuration, the extension will attempt to locate headers by searching your workspace folder and by emulating a compiler it finds on your computer.
