Build - VSCode c++ task.json include path and libraries

To configure include paths and libraries in the tasks.json file for C++ in Visual Studio Code, you can use the "args" property to specify additional compiler and linker options. Here's an example tasks.json file for a simple C++ project:

{ "version": "2.0.0", "tasks": [ { "label": "build my C++ project", "type": "shell", "command": "g++", "args": [ "-g", // Add debug information "src/*.cpp", // Your source files "-I", "${workspaceFolder}/include", // Include path "-o", "${workspaceFolder}/out/myCppApp", // Output executable "-std=c++11", // C++11 standard "-Wall" // Enable all warnings ], "group": { "kind": "build", "isDefault": true } } ] }

In this example:

  • "args": Contains the command-line arguments for the compiler (g++).
  • "${workspaceFolder}": Represents the root folder of your project.
  • "-I", "${workspaceFolder}/include": Specifies the include path. Adjust the path based on your project structure.
  • "src/*.cpp": Specifies the source files. Adjust the path or file patterns based on your project structure.
  • "-o", "${workspaceFolder}/out/myCppApp": Specifies the output executable. Adjust the path and executable name accordingly.

Make sure to modify the paths and settings according to your project structure and requirements. Additionally, replace "g++" with the appropriate compiler command if you're using a different compiler.

If your project requires linking with libraries, you can add additional entries to the "args" array, such as -lLibraryName to link with a specific library. Ensure that the library is in the library path or specify the library path using -L.

"-L", "${workspaceFolder}/lib", // Library path "-l", "myLibrary", // Link with myLibrary

Adjust these settings based on your specific project structure and requirements.
