We are getting below linking errors in my application which uses audio-video-codecs libraries of IPP Samples of version 7.1.1.013 and Core IPP Libraries of version 7.1.1.119_intel64 on Windows Server 2008 64 bit machine.

Amol,

Can you list out your linker settings? Are you building this using the Perl command line script?

Hi Chuck,

Thanks for your quick reply.

We successfully build the complete solution of audio-video-codecs using perl command script.

We are able to build again successfully all the IPP sample libraries with macro _IPP_PARALLEL_STATIC and Runtime Library : Multi-threaded DLL using Microsoft Visual Studio 2008. But we are getting above mentioned linking errors when we link these rebuild libraries with our application.

The linker settings we use are attached.

Please inform if you want more information.

Regards

Amol

Have you downloaded the threaded libraries from the website? They are separate download in IPP v7.1.

Hi Manca1,

Yes I have already downloaded these libraies and currently using them. But these linking errors still came during building my project.

You're definitely not linking all the necessary libs. Try adding this in your "Additional library folders" in linker: C:\Program Files (x86)\Intel\Composer XE 2013\ipp\lib\intel64, as well as: C:\Program Files (x86)\Intel\Composer XE 2013\compiler\lib\intel64. It should have all the necessary libs with these two folders there.

Hi Amol,

Try to add ippvm_l.lib library to the list of libraries in the project. The unresolved references are there.

Hi Manca1,

We are alreadylinking with all the IPP core libraries and compiler libraries but the errors are still present.

Hi Sergey,

We are already using ippvm_l.lib.

One thing more i want to mention for this error is that this error occured due to mp3_enc.lib which uses ipps_l.lib or ipps_t.lib. When we remove the dependecy of mp3_enc from our application we are able to build our application successfully.

Please suggest the possible reasons for this error.

Amol

Hi Amol,

It's hard to believe, because IPPS (ipps_l/ipps_t) is one of the most used libs (second after ippcore), in UMC all local libraries/applications depend on IPPS. So, the problem must be "out there". Could you show linker command line (the one shown in project properties/link/command_line) ?

Sergey

Hi Sergey,

Thanks for your support and sorry for the late reply.

Please find below the Linker command line Settings :

Amol,

Have you tried adding the ipp libraries explicitly in the Additional Dependencies linker option, instead of just adding the path?

- Chuck

Hi Chuck,

Looks like IPP libraries are linked via "#pragma comment" directives in IPP .h files.

Hi Amol, how do you know that you link ippVM library? Just in case try to add ippvm_t.lib to the "input" list of linker properties in your project. Or, ippvm.lib if you use dynamic IPP linking. This is only experiment :)

Sergey

Hi Sergey,

Thanks for your reply.

We are just trying to link with other libraries to resolve this linking errors thats why we use ippvm_t.lib.

We added ippvm_t.lib as we use static linking but the problem is still exist.

Amol

Hi Amol,

Look below. This is output from dumpbin. The first is search for ippsLn in ipps_l.lib. Second is search for the same in ippvm_t.lib. You can see that in ipps_l.lib there are external links to undefined ippsLn symbols. In ippvm_t.lib you can see the same links from some module(s) and in the bottom there are external definitions of that symbols. That means, that required symbols are defined in ippvm_t.lib.
