ippi function is undefined

shachar-arieli — Tue, 03 Mar 2015 11:07:16 GMT

I am trying to use the function ippiFilterBoxBorder and i keep getting a compiler error of
Error 4 error : identifier "y8_ippiFilterBoxBorder_16u_C1R" is undefined
Error 3 error : identifier "y8_ippiFilterBoxBorderGetBufferSize" is undefined

If i change the FilterBoxBorder function to FilterBox (which is deprecated) everything compiles and runs with no issue.
I am using the latest c++ Intel compiler 15.0.2.179 on windows

Any idea what am i doing wrong?

Hi !

Hi !

It mustn't be so.

"y8_ippiFilterBoxBorder*" along with other CPU-clones "<cpu_letter>_ippiFilterBoxBorder*" functions are in "ippimt.lib" in $(IPPROOT)/lib/<ia32 | intel64> folder.

By the way, what is the diagnostic "Error 4", "Error 3" ? I haven't seen this before. Usually, there are linker errors of this kind.

Could you tell how do you include IPP header files ? Or, you use CPU-specific include files from $(IPPROOT)/tools/<cpu_arch>/staticlib directory ?

Thanks for the quick reply.

Thanks for the quick reply.
I think the number next to the compiler error is just the index of the error

As for the include i have the following 2 lines in this order for the include directories.
$(ICInstallDir)ipp\include\
$(ICInstallDir)ipp\tools\intel64\staticlib

I am including ipp.h

If you don't specify

If you don't specify explicitly
#include "ipp_y8.h"
the inclusion of only "ipp.h" must not bring this problem, independent of include directories order.

Only in ipp_y8.h there is a redefinition, for example,
#define ippiFilterBorderGetSize y8_ippiFilterBorderGetSize
That is, instead of pure "ippiFilterBorderGetSize" the compiler, after preprocessing, looks for declaration of "y8_ippiFilterBorderGetSize".

I could suppose the following lines to reproduce this diagnostics:

#include "ipp_y8.h"

void foo()
{
    ippiFilterBoxBorderGetBufferSize();
}

This means, the redefinition exists, but declaration, which is in regular "ipp.h". I have "error C3861: 'y8_ippiFilterBoxBorderGetBufferSize': identifier not found" with this.

I tried both including the

I tried both including the ipp_y8.h and only ipp.h

The previous errors were with ipp_y8.h and i get a similar error with only ipp.h
error : identifier "ippiFilterBoxBorderGetBufferSize" is undefined

There is something else which is wrong there.

The investigation is simple:

Sergey_K_Intel — Tue, 03 Mar 2015 14:32:38 GMT

The investigation is simple:
- ipp.h should include ippi.h,
- ippi.h should have the declaration:
IPPAPI (IppStatus, ippiFilterBoxBorderGetBufferSize,(IppiSize roiSize, IppiSize maskSize, IppDataType dataType, int numChannels, int* pBufferSize))

If something wrong in nested file includes, or, you have previous IPP version (I don't remember when BoxBorder functions appeared in IPP), the requested function will be non-declared, so "undefined".

Thanks. You were correct.

Thanks. You were correct.
The issue was with a previous version of IPP i had installed.
In the options it said to use latest for compiler 15 which is what i am using but i guess somewhere it got messed up and was using a previous version

Anyway its now resolved. Thanks
