All Done!

Check g++ installation#

Open cmd and enter the following command:

g++ --version

You should see:

Linux (Debian based systems)#

Open the terminal and enter:

sudo apt update
sudo apt upgrade
sudo apt install g++

macOS#

Method 1: Installing the Xcode command line tools#

The clang and clang++ compilers come with the Xcode command line tools.

Note that when you run gcc or g++, it’ll actually run clang or clang++.

To install the command line tools, use the following command.

xcode-select --install

This will prompt for confirmation. Click ‘Install’ to begin the download and installation process. You’ll see a confirmation message when installation is complete.

Method 2: Homebrew#

Alternatively, you can install and use the Homebrew package manager to install the gcc compiler.

To install the Homebrew package manager, use the following command.

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

You also want to add Homebrew to your PATH.

echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"

Homebrew is now installed!

To use Homebrew, restart your current shell to reload the PATH.

exit

You can now use Homebrew to install packages.

To install the gcc compiler, do:

brew install gcc

gcc will now be installed.
