I'm trying to compile a c-program with openssl-references. I'm using Linux Mint 17.1 and the development package "libssl-dev" is installed.
void send_smtp_request(BIO *bio, const char *req)
gcc -o client bio-ssl-smtpcli2.c
/tmp/ccCHrti2.o: In function 'send_smtp_request':
bio-ssl-smtpcli2.c:(.text+0x1f): undefined reference to 'BIO_puts'
bio-ssl-smtpcli2.c:(.text+0x3a): undefined reference to 'BIO_ctrl'
I managed to compile your function by using :
gcc main.c -o main -I /usr/local/ssl/include -L /usr/local/ssl/lib -lssl -lcrypto -Wall
More explainations :
-I /usr/local/ssl/include adds
/usr/local/ssl/include to the include search path.
-L /usr/local/ssl/lib adds
/usr/local/ssl/lib to the library search path.
-lssl -lcrypto links libraries libcrypto and libssl
-lcrypto must follow
-lssl becuase ld is a single pass linker
Wall enables all warnings.
My guess is that you are missing
