WCHAR to QString giving error in vs2005

[ucomesdag]

When using QString::fromWCharArray(const wchar_t* , int size = - 1);

vs2005 gives the following error:

error LNK2019: unresolved external symbol "__declspec(dllimport) 
public: static class QString __cdecl QString::fromWCharArray(wchar_t const *,int)" 
(__imp_?fromWCharArray@QString@@SA?AV1@PB_WH@Z) referenced in function "public: 
void __thiscall midiIO::queryMidiInDevices(void)" (?queryMidiInDevices@midiIO@@QAEXXZ)

error LNK2019: unresolved external symbol "__declspec(dllimport)

(__imp_?fromWCharArray@QString@@SA?AV1@PB_WH@Z) referenced in function "public: 
void __thiscall midiIO::queryMidiInDevices(void)" (?queryMidiInDevices@midiIO@@QAEXXZ)

To copy to clipboard, switch view to plain text mode 

To fix this, go to Project --> Properties --> Configuration Properties -->
C/C++ --> Language, and set 'Treat wchar_t as Built-in Type' to No.

Hope it helps someone, it fixed my day...
