Entry Point Not Found in ippi20.dll

[minbo-shim]

Hi there,

I am gettingthe followingrun-time error:

The procedure entry point "ippiRotate_8u_C4R" could not be located in the dynamic link library ippi20.dll.

The header file "ippi.h"has the declaration of the function.

Any help on this would be appreciated.

This sounds relate to system environment setting. Make sure the ippi20.dll you loaded is the same version of ippi20.h file.

You can run the env.bat file from IPP directory oolsenv to make sure the correct system environment setting for IPP, another place you may check is the directory under windowssystem32 to see if there are older version of ipp*dll .

Thanks,

Hi Song,

That was it!

The Matlab (7.01)installed on my computer had createdthe preceded PATH to old IPP dll in$(MATLABROOT)inwin32over the latest Intel's IPP dll directory.

Thank you for your help.
