SMTP編譯錯誤

Question

我有一個與登錄驗證SMTP驗證碼，我試圖編譯它的Ubuntu 13.04下

，但我越來越想編譯G ++ -o命令行程序時編譯器錯誤

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 
mailogin.cpp:148:37: error: ‘login_pass’ was not declared in this scope

mailogin.cpp:190:1: error: expected ‘}’ at end of input 
mailogin.cpp:190:1: error: expected ‘}’ at end of input 

有人可以幫助我嗎？

這是我的代碼

你沒有申報login_name和login_pass。不應該是login和password，您將其作爲參數傳遞給函數smtp_send？
