At first, I run make and make quit error when run g++ -std=c++11 -c -g -Wall -rdynamic -I../include -o cryptography.o cryptography.cpp and then I solve it by upgrate openssl to 1.1.1m; but when I run make again, the similar problem show up like the picture.
Is it a error about makefile code or c++ file?
