I tried to link the shell32.dll as follows in my .pro file :

*HEADERS = hello.h*
*SOURCES = hello.cpp \*
*          main.cpp*
*win32:LIBS += C:\Windows\System32\shell32.dll*

However I got the following error :

I tried to link the shell32.dll as follows in my .pro file :

win32:LIBS += shell32.lib


I still get the same error. I am not sure how to link a dll file with QT.I
was trying to follow an old thread :
http://forum.qt.io/topic/6804/using-an-existing-dll-lib-with-qt/9

Moreover, I was expecting the examples to work right away without the user
needing to add any extra library.As a beginner, i wanted a good example for
reference and go ahead with that.

Thanks
