I also have Matlab 7 install, and that came with MKL 7.1 and IPP 2.0 runtime. This generated conflicts, so I changed the directory of Matlabs IPP to hide it from my C++ compiler, and I re-installed IPP. Now, it gives me the access violation exception when I call cvCalcOpticalFlowPyrLK. I tried hiding MKL from my application by renaming the corresponding .dll file, and it did not help. It works fine when I disable IPP, so I know this is an integration issue.<BR /><BR /> I am running Windows XP, and Visual Studio 2003. My project links to all the IPP stublibs, and currently all the IPP DLLs that it loads are from the IPP directory, at least according to VC++.<BR /><BR />Can someone suggest some things I can try to fix this? Thanks! <BR /><BR />Anatoliy Thu, 16 Feb 2006 06:30:08 GMT https://community.intel.com/t5/Intel-Integrated-Performance/OpenCV-and-IPP-Conflict/m-p/945211#M18066 akats 2006-02-16T06:30:08Z https://community.intel.com/t5/Intel-Integrated-Performance/OpenCV-and-IPP-Conflict/m-p/945212#M18067 <DIV>Hi,</DIV> <DIV></DIV> <DIV>The possible way is to rename the environment variable IPPROOT for your IPP 5.0 installation and use this name while building and running your application using OpenCV and IPP 5.0.
