MacOS assigns the name g++ as an alias to clang++ after installing the Xcode command-line tools, which you can see by using: g++ -version In most of our lectures and labs, we'll be referring to a different compiler, g++, since g++ is by far the most popular C++ compiler. InstalledDir: /Library/Developer/CommandLineTools/usr/binĪfter installation, I recommend running the clang -version command again to see if you get the above output. Otherwise, if you saw a message alike: Apple clang version 11.0.3 (clang-1103.0.32.59) Then use the following command to install the Xcode command-line tools (approve any requests it may make, the full installation can take a while): xcode-select -install

If the return came back as something akin to: zsh: command not found: clang To test that you have Clang installed, open Terminal and use the following command: clang -version

You may already have this installed, if you had been working with terminal features before this class. The easiest way to get a C++ compiler is to use Apple's provided Xcode tools, which comes packaged with a compiler called Clang. I recommend taking the time to update your system now if you are below version 10.13. You can check your MacOS version by clicking the Apple logo at the top-left, and selecting About This Mac. The following tutorial assumes you are running on MacOS version 10.13 (High Sierra) or later, but it's possible that this tutorial may still work on older versions - we simply have no way of testing. You guys have everything we need packed into a single terminal command, provided by the Apple developers.

Much of the Windows tutorial is spent just getting the Windows operating system setup with a psuedo Linux environment, called Windows Subsystem for Linux. Why do you guys have it so easy? Well, MacOS is based on the Unix OS family, and so you already have full access to Linux command-line tools - Windows users do not have this luxury. Congratulations on having a Mac! You guys most definitely have the easiest setup of the three (really, two) operating systems we provide tutorials for.
