link problem using IPP

backyardigan — Mon, 06 Oct 2008 22:46:33 GMT

Hi, All:

I'm a beginner of IPP. After configuration followed the "Getting Started with Intel IPP", I tried some sample code which successfully went through. Then I wanna try some simple function code, like below. The problem is that this code could compile (Ctrl+F7) but failed when I tried to link using F7. It said: "unresolved external symbol _ippiMalloc_8u_C3@12 referenced in function _main"

Can anybody please help out.

Thanks,

==================================

#include "stdafx.h"
#include

int main()
{
IppiSize size={320,240};
int stride;
Ipp8u* pSrc = ippiMalloc_8u_C3(size.width,size.height,&stride);
return 0;
}

You should link your application with ippi.lib. In visual studio use properties ( of your project ) linkerinputadditional dependencies.

I am running into the same issue. I checked and found that under the projects options that I was not refrencingia32stublib which is where the lib you mentioned resides. This did not work for me, im still getting the same error.

I just trid this sample in MSVC 2008, link with ippi.lib and there is no building errors. Kind of strange.

That's grate. Are you using pre-compled headers? Where there any settings you had to change in VS?

Great! this works. I tried this method and also adding ippi.lib to project/properties/linker/command line/additional options.

Thanks a lot!

The error i keep getting is :
Error 15 error LNK2001: unresolved external symbol _ippMalloc@4 jpegbase.obj
for each of the object files that VS 2005 generates when it trys to build

In options > VC++ dirs > Lib Files i have added :
C:Program FilesIntelIPP5.3.1.064ia32lib andC:Program FilesIntelIPP5.3.1.064ia32stublib

In the project properties > linker > input > Additional Dependencies :
"C:Program FilesIntelIPP5.3.1.064ia32stublibippi.lib"

The includes and bin folders have been added to the C++ directories as well.

I have pre compiled headers disabled from the default of "use precompiled headers" to resolve an issue with stdafx.h not being included in the origal H files.

What other settings could i change to get this error to stop occuring? I have looked into trying to use the same paramters the build32.bat file uses to build the application but I dont understand batch that well. If you could provide these parameters I could bypass any issues that could be because of the IDE and run the compiler and linker directly.

Thanks,

Hello, ippMalloc function is defined in ippCore library, so you need to add ippcore.lib into your linked libraries list.

Well, as I can see you have jpegbase.obj file which is part of JPEG sample. For IPP JPEG sample you will also need to add ipps.lib, ippcc.lib, ippcv.lib and ippj.lib
