Hi I am building qtdrv in windows but error occurs, I've installed Qt creator 4.0.2(Qt 5.7.0) and mingw-w64.

PS D:\go\src\github.com\visualfc\goqt\qtdrv> qmake "CONFIG+=release"
PS D:\go\src\github.com\visualfc\goqt\qtdrv> mingw32-make

set this ENV before qmake

set QMAKESPEC=C:\Qt\<version>\<path>\mkspecs\win32-g++
