to build opencv2.1 dynamic library with IPP 6.1. I'm very sure that IPP was static linked to the dll, because that I saw the IPP libs are present in the external libraries when I build opencv with vc2008.
But when I run my applications with the new built opencv libraries,I found nothing was accelerated.
So I use the code bellow to check whether IPP is working:
cvGetModuleInfo provides information about external DLLs if OpenCV load ones. It work in previous OpenCV versions for IPP because that time IPP was linked dynamically. Now it is linked statically, so you can not get info through this function.
You can try to compare performance of OpenCV functions which get optimized with IPP
