This error occurs when the linker cannot find an Intel® IPP function in the libraries and object files it searches. The three most common reasons for this error are listed below:

The Required Intel IPP libraries have not been linked to or are not found in the linker search path. Please check the documents below to find out how to link to the Intel IPP dynamic libraries:
The Intel IPP function name is misspelled in the source code. To verify the correct spelling of an Intel IPP function you can:
- Search the Intel IPP header files. For example, the header files for the Pentium® processor package are located in the folder IPP6.0.x.x.xia32include.
Two versions of the Intel IPP installed on the development system are causing a conflict. You can resolve this by:
- Uninstalling the oldest Intel IPP version from the development system by using Control Panel » Add or Remove Programs » Change or Remove Programs.
- Uninstalling the oldest Intel IPP Runtime Installer version from the development system by using Control Panel » Add or Remove Programs » Change or Remove Programs.
- Verify that system and user environment variables point to the latest version of the Intel IPP.

Hello cakrudy,

The function ippiRGBToGray is declared in the ippcc.h file. Could you please check if color conversion library : ippcc.lib (and ippi.lib ipps.lib ippcore.lib libiomp5md.lib) was linked in your project?

Please refer to http://software.intel.com/en-us/articles/intel-integrated-pe.....compilers/.

What you need is to tell the compiler where to find the library.
You can set compiler option in project property to link any third-party library(including ipp and other library) via
1) Add the library
Add ippi.lib ippj.lib ippcv.lib ippvc.lib to the box of
project>>properties>>linker>>input>>addit ional dependencies
2) Add the library path
add the lib's path to project>>properties>>link>> General>> Additional Library Directories.
3) and add header file path
add the header file to project>>properties>>Fortran>>General>>Ad ditional include directory.

Regards,
Ying
