ld: символ (ы) не найден с OpenSSL (libssl)

Question

Я пытаюсь построить TorTunnel на своем mac. Я успешно установил библиотеку Boost и ее файлы разработки. TorTunnel также требует OpenSSL и его файлы разработки.

Я установил их в /usr/lib/libssl.dylib и/usr/include/openssl /.

Когда я запускаю команду сделать это будет ошибка я получаю:

make: *** [torproxy] Error 1 

Любая идея, как я могу это исправить?

Answer 1

Вам также нужен libcrypto.

Изменить свою ссылку линия:

g++ -ggdb -g -O2 -lssl -lcrypt ... as before ... 

Answer 2

По крайней мере, на отсутствующих символов не является частью libssl но часть libcrypto:

diciu:~ diciu$ nm /usr/lib/libcrypto.dylib | grep PEM_read_bio_RSAPublicKey 
00031d20 T _PEM_read_bio_RSAPublicKey 

Добавить «-lcrypto» в строке компиляции ,

Answer 3

Если libcrypto уже установлен в/opt/local/lib, измените флаг -lcrypt на флаг -lcrypto.

g++ -ggdb -g -O2 -L/opt/local/lib -L/usr/lib -lssl -lcrypto -lboost_system-mt
