topic Hello Sergey, in Intel® Integrated Performance Primitives

Can't build audio-video-codecs folder

Clément_C_ — Tue, 12 Mar 2013 15:21:11 GMT

Hello,

I followed the different steps to setup the main sample (ipp-samples.7.1.1.013) and I'm trying to build the audio-video-codecs by typing the line "perl build.pl --cmake=audio-video-codecs,ia32,vc2008,s,st,debug"

Build fails with the following error:

"6>..\..\..\..\sources\audio-video-codecs\application\common\src\umc_app_utils.cpp(44) : error C2065: 'ippCpuAVX2' : undeclared identifier"

I am using all the software required (Intel® Composer XE 2011 SP1, CMake* 2.8.8, Perl 5.12.2), except IPP 7.0 instead of IPP 7.1. Could that explain the error?

I am looking forward to your feedback, thanks in advance.

Hi Clement,

Yes, the version difference could be the reason. AVX2 appeared in 7.1. You can manually update (simply comment everything around ippCpuAVX2) umc_app_utils.cpp file to exclude corresponding lines 43 and 44.

Regards,
Sergey
