Finally!
Hi Gustavo,
Firstly, thanks so much for making this library!
Here is the steps I went through to make it working: (on Windows 7 64bit)
* set GOARCH=386
* set CPATH=C:\MinGW\include;C:\Qt\Qt5.1.1\5.1.1\mingw48_32\include;C:\Qt\Qt5.1.1\5.1.1\mingw48_32\include\QtCore\5.1.1\QtCore
* set LIBRARY_PATH=C:\MinGW\lib;C:\Qt\Qt5.1.1\5.1.1\mingw48_32\lib
* set PATH=C:\Qt\Qt5.1.1\5.1.1\mingw48_32\bin;C:\MinGW\bin;%path% (!important, put Qt's path in front of MinGW's path otherwise it'll complain libstdc++-6.dll missing as Qt's path contains a different libstd++-6.dll)
Then you should be able to go get/build the code.
Somewhere around those lines I think I did something else, but maybe they're not needed.
Hope this helps for whomever want to try it on Windows.
Thanks,
Jackie
