Link error of _MSC_VER mismatch after build Qt 4.8.4 specifically for VS2012

[justDance]

I followed http://stackoverflow.com/questions/12113400/compiling-qt-4-8-x-for-visual-studio-2012/14928303#14928303 to build Qt 4.8.4 specifically for VS2012, but got link error: qtmaind.lib(qtmain_win.obj) : error LNK2038: mismatch detected for '_MSC_VER': value '1600' doesn't match value '1700' in main.obj

I checked configure.cache under my qt folder, it is showing: -platform win32-msvc2012

Does anybody know what is wrong here? Thanks

You probably linked it to the wrong library(.dll/.lib) or objects(.obj) compiled with older versions of Visual Studio (VS2010, VS2008, etc).

I tried two options:

1. use command
   configure -mp -opensource -nomake demos -nomake examples -platform win32-msvc2012

and 2) 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
then use command configure -mp -opensource -nomake demos -nomake examples -platform win32-msvc2010

both gave me the same error. I can not see any wrong configuration in my build...
