One of the best video tutorials I've ever used. Thank you. I used it to help me find my way to build openSSL 1.0.2 and even though there were differences, I got there. Thank you so much!

Thank you, Kim! I am building a node application on windows and need to incorporate SSL soon and this is just what I was looking for :)

안녕하세요. 덕분에 빌드성공했습니다. 대단히 감사드립니다.
질문이 하나 있어서요.
OpenSSL이 기본적으로 UNICODE로 빌드되는것 같은데요, MBCS로 빌드할려면 어떻게 해야 할까요?
시간되실때 답변부탁드립니다. 감사합니다.

I get this error from cpan -i Text::Template, how do I fix it?

>(error): Could not expand [Text::Template]. Check the module name.

For cpan files, I get dmake is not recognized as an internal or external command, operable program or batch file.

Dmake -- NOT OK
