неопределенная ссылка на `EVP_sha3_256 '

Question

Я завершаю свою программу на С ++ с помощью ввода:

g++ main.cpp crypto/Sign.cpp -o main -lssl -lcrypto && ./main

К сожалению, я получил эти выходные данные:

Итак, что случилось? Как я могу решить эту проблему?

OpenSSL, который я использую:

#:~$ which -a openssl
/usr/local/bin/openssl
/usr/bin/openssl
#:~$ openssl version
OpenSSL 1.1.1-pre5 (beta) 17 Apr 2018

В crypto / Sign.h он включает:

#include <openssl/conf.h>
#include <openssl/ec.h>    // for EC_GROUP_new_by_curve_name, EC_GROUP_free, EC_KEY_new, EC_KEY_set_group, EC_KEY_generate_key, EC_KEY_free
#include <openssl/ecdsa.h> // for ECDSA_do_sign, ECDSA_do_verify
#include <openssl/err.h>
#include <openssl/evp.h>
