Tring to compile your server in ubuntu :

/usr/bin/g++ -fdiagnostics-color=always -Wall -std=c++17 -O0 -g $(find /home/vagrant/ws28 -type f -iregex '.*\.cpp') -I//home/vagrant/libuv/include/ -I/home/vagrant/ws28/src -L/home/vagrant/libuv/build -luv -lssl -lcrypto -o /home/vagrant/ws28/ws.exe

getting :

I think the example server is outdated right now, should be using std::string_view
