Problem with OpenCV and IPP 5.1

tsdmilan — Mon, 17 Jul 2006 11:45:51 GMT

Hi,

I used to call the IPP functions via OpenCV in my programs. Recently I upgraded the IPP from 5.0 to 5.1, and found that OpenCV fails to find the 5.1 add-on modules (confirmed by calling GetModuleInfo()). Is there compatibility problems between them? Or any configuration settings I have missed? Thanks.

Regards,

Milan.

Hi,

Starting from Intel IPP5.1, we add version for DLL file. For example, ippac.dll is changed to ippac-5.1.dll. Could that be problem for question?

Hi,

Yes, I think the new file naming method is the problem. If I revert the filename back to what it looks in version 5.0, OpenCV can locate the files correctly. My only concern is whether this would have any side effect, such as broken function pointers?

Thanks.

Milan.

Milan,

Some DLLs have dependence on other DLLs. For example, ippcv-5.1.dll depends on ippcore-5.1.dll. Manully changing the name may bring some issues.
