Wie man C++ undefined reference to symbol 'BIO_ctrl_pending@@OPENSSL_3.0.0' behebt

Problem:

Beim Versuch, Ihr C++-Programm, das OpenSSL verwendet, mit einem Befehl wie

build_cmd.sh

g++ -o myprogram myprogram.cpp -lssl

g++ -o myprogram myprogram.cpp -lssl

zu kompilieren, sehen Sie die folgende Fehlermeldung:

linker_error.txt

/usr/bin/ld: /tmp/ccEB0Pid.o: undefined reference to symbol 'BIO_ctrl_pending@@OPENSSL_3.0.0'
/usr/bin/ld: /lib/x86_64-linux-gnu/libcrypto.so.3: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

/usr/bin/ld: /lib/x86_64-linux-gnu/libcrypto.so.3: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

Lösung

Sie müssen crypto sowie ssl linken:

fix_build.sh

g++ -o myprogram myprogram.cpp -lcrypto -lssl

g++ -o myprogram myprogram.cpp -lcrypto -lssl
