In this article, we will discuss how to configure g++-13 and g++-14 in Visual Studio Code (VS Code) tasks.json on macOS. We will cover the key concepts and provide detailed instructions on how to set up the tasks.json file to build C++ programs using g++-13 and g++-14.

Introduction

If you are a C++ developer working on macOS, you might have encountered issues while building your programs using the default g++ compiler. The default g++ compiler on macOS is usually outdated, and it may not support the latest C++ standards or features. In such cases, you can install and use newer versions of g++, such as g++-13 and g++-14, to build your C++ programs.

In this article, we will discuss how to configure g++-13 and g++-14 in VS Code tasks.json on macOS. We will cover the following topics:

• Installing g++-13 and g++-14 on macOS
• Creating a tasks.json file in VS Code
• Configuring tasks.json to build C++ programs using g++-13 and g++-14

Installing g++-13 and g++-14 on macOS

Before we start configuring tasks.json, we need to install g++-13 and g++-14 on our macOS system. We can use Homebrew, a package manager for macOS, to install the latest versions of g++.

To install Homebrew, open a terminal window and run the following command:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Once Homebrew is installed, we can install g++-13 and g++-14 using the following commands:

brew install gcc@13brew install gcc@14

This will install g++-13 and g++-14 in the /usr/local/Cellar directory.

Creating a tasks.json file in VS Code

Now that we have installed g++-13 and g++-14 on our system, we can start configuring tasks.json in VS Code.

To create a tasks.json file, open VS Code and create a new file with the .vscode extension in the root directory of your project. Name the file tasks.json.

Configuring tasks.json to build C++ programs using g++-13 and g++-14

Now that we have created the tasks.json file, we can configure it to build C++ programs using g++-13 and g++-14.

Here is an example tasks.json file that configures g++-13 and g++-14 to build C++ programs:

{ "version": "2.0.0", "tasks": [ { "label": "Build with g++-13", "type": "shell", "command": "/usr/local/Cellar/gcc@13/13.1.0/bin/g++-13", "args": [ "-std=c++17", "-o", "${fileDirname}/${fileBasenameNoExtension}", "${file}" ], "group": { "kind": "build", "isDefault": true } }, { "label": "Build with g++-14", "type": "shell", "command": "/usr/local/Cellar/gcc@14/14.2.0/bin/g++-14", "args": [ "-std=c++17", "-o", "${fileDirname}/${fileBasenameNoExtension}", "${file}" ], "group": { "kind": "build", "isDefault": false } } ]}

Let's go through the configuration options:

• version: This specifies the version of the tasks.json schema. In this example, we are using version 2.0.0.
• tasks: This is an array of tasks that can be executed in VS Code.
• label: This specifies the name of the task that will be displayed in the VS Code task bar.
• type: This specifies the type of task. In this example, we are using a shell task, which runs a command in the terminal.
• command: This specifies the path to the g++-13 or g++-14 compiler. We can find the path to the compiler using the which command in the terminal.
• args: This is an array of arguments that will be passed to the compiler. In this example, we are passing the -std=c++17 flag to enable C++17 support, the -o flag to specify the output file name, and the `
