Let's get started with building AFLGo (on Ubuntu 20.04) and fuzz the target libxml2:
git clone https://github.com/ducdatdau/AFLGO.git
cd AFLGO
export AFLGO=$PWD
chmod 777 *
# Build AFLGo
sudo ./build.sh
sudo pip3 uninstall pydot networkx -y
pip3 install networkx==2.5 pydot==1.4.2
# Build AFLGo
sudo ./build.sh
# When you fuzz for the very first time...
sudo sh -c 'echo core > /proc/sys/kernel/core_pattern'
# Fuzz the target libxml2
cd examples
./libxml2-ef709ce2.sh
