Node-gyp: Build errors relating to winsock on Windows

[swaj]

This same output is generated by two different build machines:

• One running Windows 7 with Visual Studio 2015 Professional, Windows SDK 8.1, Python 2.7.12.
• One running Windows 7 with only npm install -g windows-build-tools

It's worth noting this code builds perfectly on Linux and OSX, so I'm at a bit of a loss. I'm sure I've done something wrong, but after hours of scouring my code, I just can't find it. Can anyone give me any idea why this might be happening?

I've resolved this. It was caused by me including node.h _after_ I had included <openssl/err.h>. My guess is that libuv uses Winsock2, and OpenSSL uses Winsock1, and if you include version 1 before version 2, bad things happen. Cheers :)

Hi similar problem occured to me while building my qt project. Am using openssl as well as libssh in my project. I never included node.h in my project file. So what should i do.
My project worked well when i installed libssh and openssl through vcpkg - libssh version 0.7.6-1 and openssl v1.0.2q.
Wen I moved to never libssh and openssl version the above problem occured.
With openssl alone my app works, when including libssl my app throws lots of error.

[Bharathinandhan]

I found the solution. Though I didnt use any of the winsock2.h or windows.h header files in my application. I found the header files shuffled in libssh library and I had to make changes(first winsock2.h then windows.h) in source code and build it once again freshly. It worked for me.
