@andyyuan78 Sorry for my late reply! It looks like a tricky linking error, but I am not sure about the problem. I guess you could build by hand with command like g++ -I./kernel/ -O3 -march=native -mtune=native -funroll-loops -fPIC -Wall -std=c++11 -o ./bin/quora_online driver/quora_online.cpp -lgflags.
