At first i checked with that configuration but later on i have downloaded qt sdk 5.1.1 and qt creator 2.7.2 and microsoft visual studio 2012 for windows desktop and working on this configuration still iam not getting the map.It is showing as invalid null pointer
The qt version which iam using is qt-windows-opensource-5.1.1-msvc2012-x86-offline.exe
and compiler is Microsoft Visual Studio Express 2012 for Windows Desktop - ENU
