How to use C++ with Jupyter-Notebook at Linux

1. Install conda

You can install the mini version: https://docs.conda.io/en/latest/miniconda.html#linux-installers
Or you can install the full version: https://www.anaconda.com/products/individual

‘conda is nothing but another python virtual environment manager’, you can think it like this.

2. Install jupyter-xeus

conda create -n cling
conda activate cling
conda install xeus-cling -c conda-forge

3. Add C++ kernel to jupyter-notebook

I suppose you already have a normal python version of jupyter-notebook installed:

jupyter kernelspec install ~/miniconda3/envs/cling/share/jupyter/kernels/xcpp17 --user

4. Open, Create and Test

Open jupyter-notebook, create a c++ script, run the following codes:

#include <iostream>
std::cout << "Hello World!";
