准备工作

To run the labs, you’ll need the following software:

g++ version 8.x
clang-tidy version 6 or 7
clang-format version 6 or 7
cmake version 3 or later
libpcap development headers (libpcap-dev on Debian-like distributions)
git
iptables
mininet 2.2.0 or later
tcpdump
telnet
wireshark
socat
netcat-openbsd
GNU coreutils
bash
doxygen
graphviz
Note: there are at least three versions of netcat. You won’t be using it much, but when you do, we will assume you’ve got the OpenBSD variant. Others might also work, though it is possible that they will require different commandline flags.

We’ve tested the labs with recent Debian-derived systems (Ubuntu 18.04 and similar) and Arch Linux. In all likelihood, other modern Linux distributions will also work.

问题1：

g++ -v or gcc -v的版本是小于8，就会导致cmake的时候失败


解决：

sudo apt-get update
sudo apt-get install gcc-8
sudo apt-get install g++-8
cd /usr/bin
sudo rm gcc g++
sudo ln -s gcc-8 gcc
sudo ln -s g++-8 g++
