Linux 8.1 error on IppInit() Error:ippStsWaterfall: Cannot load required library

[AndrewC]

I am using Linux Intel64 version of IPP8.1 ( part of Composer XE 2013 SP1) and when I call IppInit I get the following (non-fatal) error.

IppInit() Error:ippStsWaterfall: Cannot load required library, waterfall is used.

I am linking with the single threaded dynamically linked version
 

ldd shows

And what you say about ippGEN would explain why the Centos 6.5 machine does not show the error  as it is an old SSSE3 machine with the following capabilities.

To remove ippGEN and other unnecessary domains from your application you should modify your Makefile or project settings to link only necessary IPP domains.

I have the question: why do you link your application with dynamic libraries? You use only several IPP functions and from my point of view to link the application with IPP static libraries gives much smaller footprint and small size of application package in the result.

ippGEN has special optimization for SSSE3 - it is why no problem on this configuration.

Pavel,

I DO NOT link against ippgen or any unnecessary IPP domains. That is why it is odd ippgen is being loaded.

I link against the IPP dynamic libraries as the applications is not monolithic. It is a number of .so that link against IPP. I would end up with all sorts of initialization issues if each .so linked against it's own copy of a static IPP. It is much cleaner to link against the shared IPP libs.

OK , problem solved.

icpc -ipp <options> -o myapp

on the link line causes a dependency on all the IPP libs. Removing -ipp and listing only the libs needed fixes the ippgen dependency

[AndrewC]

Just as a suggestion maybe the default behavior of -ipp on the link line should be to NOT auto-link deprecated libraries.

Andrew,

thank you for the info.
