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

• • Install perl (I used [1] and choose 64 bit version)

• • Build/install in say C:\QtHacked.

• • Cd into this directory and 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 "x64 Cross Tools".

• • Then paste the following (-mp for multiprocessor use during build). (Adjust perl path as necessary.)

set QTDIR=C:\QtHacked\Qt
set PATH=%QTDIR%\bin;%PATH%
set QMAKESPEC=win32-msvc2012
cd /D %QTDIR%\
set PATH=C:\Perl64\bin;%PATH%
configure -release -mp -opensource -platform win32-msvc2012

Then go brew a pot of coffee. If something fails at this point, you probably didn't install "Update 2" for VS 2012.

nmake
