Use external DLL ?

[pl01]

Hi,

I have a project that I build with QTCreator 2.1 beta. I have a PureLight.DLL file for the first project where I declare my methods like this

__attribute__((dllexport)) int plGetError();

In another application, I would like to use this DLL, and so I use the following code:

__attribute__((dllimport)) int plGetError();

But when I build my application it gives me this error message :

undefined reference to '_imp_plGetError'

What does it mean, do you have an idea ?

Thanks
