• To compile Qt with VS 2012 (VS 11) for 64bit (not quite tested yet..):

• • Install perl (I used [1])

• • Build/install in say C:\Qt.

• • Augment windows environment PATH with C:\Qt\bin.

• • git clone git://gitorious.org/qt/qt (this gives a version, not sure which,in this case as per 6/19/2013, mkspecs/qconfig.pri provides version info: QT_VERSION = 4.8.5, a prelease?). Alternatively, better?, find zipped file of official release [2].

• • This is bug Qt 4.8.5 doesn't compile with VC 11, marked P2:important: you must replace HashSet.h in src\3rdparty\webkit\Source\JavaScriptCore\wtf with HashSet.h.

• • Use VS command prompt (use "Developer Command Prompt" (??) or better "x64 Cross Tools" (??))

• • Then paste the following (-mp for multiprocessor use during build).

set QTDIR=C:\Qt
set QMAKESPEC=win32-msvc2012
cd %QTDIR%
configure -release -mp -opensource -platform win32-msvc2012

Then

nmake
