Windows Build Issue under MINGW / MSYS (gcc 4.8.1) about sgminer HOT 8 CLOSED

btw - compiling with a fresh dump of the repo taken from 10:40am PST 1/16/2014 - the compile errors are now as follows:

Hey folks,

I was able to compile a build successfully so I'll go over a tidbit that helped me.

First, do NOT use the latest version of MingW. The way i got it to work was to go through the Windows_Build txt file on CgMiner 3.7.2 and install the EXACT version of MingW listed (google search mingw-get-inst-20120426 and install only that).

I'd say 95% of the errors can be resolved by removing the latest version, installing the older one listed, and starting from scratch.

Also, when downloading the "PKG-CONFIG" files, make sure you chooser Version 2 because you'll notice Version 3(latest) does not have a DEV package download.

I have created a fork of the directions here 👍

Merged.

This issue is caused by the use of -D WIN32_LEAN_AND_MEAN

from sgminer.

The fix for the winsock issue can also be resolved by including winsock2.h before windows.h
credit goes to Bufius the vertminer author for figuring it out.

Here is the error:
mingw\include\ws2tcpip.h:38:2: error: #error "ws2tcpip.h is not compatible with winsock.h. Include winsock2.h instead."

@tonobitc this has been merged with your pull request some time ago.

@ninjitsu is it still present?

from sgminer.

No further input, seems fixed. Reopen if necessary.
