copied!<p>Windows and Unix based OS are completely two different things. Windows 7 is an NT Os with an NT subsystem (or two if x86_64) which consist of WIN32 (+ WIN64 if you can run 64-bit PEs).<br> The windows subsystem give a a well defined set of API which is called <a href="http://msdn.microsoft.com/en-us/library/cc433218%28VS.85%29.aspx" rel="nofollow">WINAPI</a> (which don't contains things like .NET or DirectX). For example The API for dealing with Networking API is called Winsock.<br> The main API for cryptgraphic Api is called <a href="http://msdn.microsoft.com/en-uk/library/aa380255%28v=vs.85%29.aspx" rel="nofollow">CyptoAPI</a> (See Also <a href="http://msdn.microsoft.com/en-uk/library/aa388162(v=vs.85).aspx" rel="nofollow">http://msdn.microsoft.com/en-uk/library/aa388162(v=vs.85).aspx</a>). Most Of it's functions are located in %SystemRoot%\System32\<a href="http://msdn.microsoft.com/en-us/library/aa379884%28v=vs.85%29.aspx" rel="nofollow" title="Crypt32.dll Versions">Crypt32.dll</a> (unless you're using 32-bits binaries on 64-bits windows version).<br> I tried to look for SSL functions/c++ classes, but I didn't found them yet (Maybe there are part of .Net or something else)</p> <p>Actually, you don't want to use the windows subsystem Native functions. Your're trying to get ruby running under windows. I don't know which compiler you're using, but it doesn't seems to be cl (which is used in Microsoft Visual Studio). OpenSSL are an API which provide cryptography C Functions. Windows is using different ones So, It won't work since it is OpenSSL functions the linker is looking for in SSL shared objects files.</p> <p>What you're currently wanting to use programs which are written for using API's present in Unix OS like POSIX.</p> <p><br>Microsoft designed several things for this: <a href="http://technet.microsoft.com/en-uk/library/cc771470.aspx" rel="nofollow" title="Subsystem for UNIX-based Applications">SUA</a> will give a base system with X11 gcc and make. Many libraries required to compile ruby will be missing. So, you'll probably want to search some pre-compiled <a href="http://web.archive.org/web/20130406032142/http://www.suacommunity.com/SUA.aspx" rel="nofollow">packages</a> on this <a href="http://web.archive.org/web/20130406032130/http://www.suacommunity.com/" rel="nofollow">site</a>.</p> <p>Another approach is to make the system recognize the ELF format and wrap linux systems calls which allow to run <a href="http://lbw.sourceforge.net/" rel="nofollow" title="LBW: Linux Binaries on Windows">linux binaries</a> without emulation. But since you're using windows 7, the sentence is "too bad for you" <a href="http://atratus.org/" rel="nofollow">:)</a></p>
