libssh问题编译问题未定义的错误

Question

嗨，我是一个全新的c++新手，我正在尝试建立一个ssh连接，这里是我的代码，它被指出给我，我需要链接库…这是怎么做的？

#include <libssh/libssh.h>
#include <stdlib.h>

int main()
{
  ssh_session my_ssh_session;
  my_ssh_session = ssh_new(); 
  int verbosity = SSH_LOG_PROTOCOL;
  int port = 22;
  ssh_options_set(my_ssh_session, SSH_OPTIONS_HOST, "localhost");
  ssh_options_set(my_ssh_session, SSH_OPTIONS_LOG_VERBOSITY, &verbosity);
  ssh_options_set(my_ssh_session, SSH_OPTIONS_PORT, &port);
  ssh_free(my_ssh_session);
}

我一直收到这个错误

[brett@badbox sshcpp1]$ make
g++ -Wl,-O1 -Wl,-z,relro -o sshcpp1 main.o   -lQt5Core -lpthread 
main.o: In function `main':

/home/brett/sshcpp1/main.cpp:13: undefined reference to `ssh_free'
collect2: error: ld returned 1 exit status
make: *** [sshcpp1] Error 1

Outocomplete似乎正在使用ssh库。

我做错了什么？？

您需要通过将-lssh添加到链接器命令来链接libssh。
