Ensure your gcc version is >= 8 with `gcc --version`. Otherwise, install it (on Ubuntu) with:
```bash
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get install gcc-8 g++-8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-8 800 --slave /usr/bin/g++ g++ /usr/bin/g++-8
sudo apt-get install gcc-9 g++-9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 900 --slave /usr/bin/g++ g++ /usr/bin/g++-9
```
