c++ QString::toStdWString QT 4.6.4 version Linking error in visual studio 2008
===

I have updated my Qt library version to **QT 4.6.4** and build successfully.

Command used for configuring Qt: **configure -confirm-license -no-dsp -no-vcproj -stl -debug-and-release -opensource -platform win32-msvc2008**

In my application we are using QString functions **toStdWString**, **fromStdWString** for converting **std** string to **Qstring** and viceversa.

Even though the Qt is built with stl support (**-stl option**), still while linking my application with new version QtCored4.dll, am getting the bellow linking error.

Please let me any body else have experienced this issue.

Please help, how we can resolve this issue, is there something wrong in configure command ?

Thanks in advance.
