我有这个带有登录身份验证的 SMTP 代码，我正在尝试在 Ubuntu 13.04 下编译它
但是在尝试使用 g++ -o 命令行编译程序时出现编译器错误
mailogin.cpp: In function ‘bool smtp_send(std::string, int, std::string, std::string, std::vector<std::basic_string<char> >, std::string, std::string, std::string)’:
mailogin.cpp:148:17: error: ‘login_name’ was not declared in this scope

有人能帮我吗？
