CPU matching problem

[Shibby_Sadot]

I have built ippopencv with the T7 tag. It runs fine on a Pentium D machine, but when I run it on a Core2Duo I get the following message:

Set ipp library error
No ipp matching to cpu was found during the waterfall

Note that I am using ippopencv built with IPP 6.0. Any ideas?

Thanks!

T7 code is optimized for Intel Pentium 4 processors with Streaming SIMD Extensions 3 (SSE3)

For Intel Core2Duo, you may use p8 code.

To understand the cpu code used in Intel IPP optimized libriares, please check this Intel IPP Knowledge Base at

http://software.intel.com/en-us/articles/intel-integrated-performance-primitives-intel-ipp-understanding-cpu-optimized-code-used-in-intel-ipp/

By the way, we just released Intel IPP v6.1, you may also try this lateste version too. For more release info, visit Intel IPP product site at http://software.intel.com/en-us/intel-ipp

Hope it helps.
