下载SMTP客户端从链接SSL/TLS库：https://www.codeproject.com/Articles/98355/SMTP-Client-with-SSL-TLS][1]。致命错误：OpenSSL的/ e_os2.h：没有这样的文件或目录
包括在我的NetBeans项目“头文件”文件夹，将获取的main.cpp文件摆脱错误的CSmtp.h文件。
我得到的编译错误“致命错误：OpenSSL的\ ssl.h：没有这样的文件或目录”添加“OpenSSL的”文件夹到NetBeans项目目录的根目录之前。
现在加入“OpenSSL的”文件夹后，我收到错误：
fatal error: openssl/e_os2.h: No such file or directory
错误Netbeans的控制台：

我的解释是，编译器能够找到“ CSmtp.h”包括，为 “OpenSSL/ssl.h” 包括，但解决不了 “的OpenSSL/e_os2.h”。不知道为什么，编译器无法解析“e_os2.h”因为ssl.h在OpenSSL的文件夹“e_os2.h”一起发现的。您对这个编译器错误的专家建议将不胜感激。
