How to Set Up C++ Programming Environment

To do the assignment, it is necessary to set up the C++ programming environment. Namely, you need Git , C++ Compiler (of course!) and cmake installed in your computer. This document targets MacOS, Ubuntu and Windows. Depending on the versions of the OS, you may encounter some problems, but I encourage you to sove it by yourself first. These toos are very poupular and there are tons of information on the internet. If you solve the problem, let the instructer know on the slack the problem and solution together with the version of your OS.

Git

Git is ncessary to download and upload the assignments. Let's see if the git is already installed in your computer. Type the following command and see if the version of the git is shown.

$ git --version

If git is not installed on your computer, read the following document to install

C++ Compilar

For linux, type

$ sudo apt-get install build-essential

For mac, install Xcode first. The Xcode is currently available at

https://developer.apple.com/xcode/

Then, install command line tool with the following command:

$ xcode-select --install

If the install is successful, following command backs the version of the C++ compilar

$ clang --version

For windows, downlod Visual Studio from there (it's free for students)

CMake

CMake is used to configure the project i.e., making a project file to build the code based on the setting written in CMakeLists.txt.

Type following commands to check if you have cmake or not in your compuer.

$ cmake --version

If not, download the cmake from the link below and instal in your computer.

Alternatively, you can install cmake using a package manager such as apt-get for Ubuntu and brew for MacOS.
