Hi,
What I encountered is that the automatic search function of QLibrary didn't do what I expected. It needed the .dll postfix.
Also make really sure your library is in the same folder as your executable. So if in de debug mode, place it in the shadow build debug folder. It will not look into your project folder when you build shadow builds.

Hi,

What compiler did you use to create the DLL and which one are you using for your application ?

[LeaA]

how can i know it?
the dll compilied in VS 2008 and the app in qt 5.3.1

[SGaist]

So, is the your Qt 5.3.1 also compiled with VS2008 ?

[LeaA]

No.
should i?
why?

[SGaist]

Yes it should.

Visual Studio rule number one: Everything must be compiled with the same version of Visual Studio.

The different versions of Visual Studio are not compatible one with the other.
