Compiling Qt 4.8.x for Visual Studio 2012

Solution 1:

Qt 4.8.3 with Visual Studio 2012 x64 (should also work with 4.8.2)

1. Install Strawberry Perl

2. Download Qt 4.8.3 source code from http://qt-project.org/downloads

3. Go to mkspecs\win32-msvc2010. Open qmake.conf and change:

   QMAKE_COMPILER_DEFINES  += _MSC_VER=1600 WIN32
   

   to:

   QMAKE_COMPILER_DEFINES  += _MSC_VER=1700 WIN32
   

4. Replace qt-everywhere-opensource-src-4.8.3-x64\src\3rdparty\webkit\Source\JavaScriptCore\wtf\HashSet.h by this HashSet.h.

5. Start "VS2012 x64 Native Tools Command Prompt"

6. Switch to Qt 4.8.3 source directory (the directory that contains configure.exe)

7. Run:

   configure -mp -opensource -nomake demos -nomake examples -platform win32-msvc2010
   

8. Followed by:

   nmake
   

I programmed a tool called BlueGo which automatically downloads Qt 4.8.3 and builds it with VS2012 x64: http://bluego.vertexwahn.de (also works with VS2010 x64) (it just does what I described above automatically)

Solution 2:

Qt 4.8.4 needs less tweaking than described by Vertexwahn above.

• The HashSet still has to be fixed (see fix of Vertexwahn) after Qt has been extracted from archive.
• Platform win32-msvc2012 is supported out-of-the-box though (also works for 64bit in the 64bit environment, don't ask why they name it Win32).

So simply replace the HashSet.h and compile.

Solution 3:

Just creating a win32-msvc2012 directory with the changes below didn't work for me, there is more editing necessary. What exactly is necessary is described in the thread you already linked.

What I did, I went to win32-msvc2010.

There, open qmake.conf and change

QMAKE_COMPILER_DEFINES += _MSC_VER=1600 WIN32

to

QMAKE_COMPILER_DEFINES += _MSC_VER=1700 WIN32

Then I could configure using win32-msvc2010.
