IPP Dynamic Link Problem Under Ubuntu

jiapei1001 — Sat, 01 Nov 2008 13:44:18 GMT

I'm wondering whether IPP could be dynamically linked? Those libipp**merged.a files are really annoying... I mean, I just don't wanna link those .a files, instead, I'm wondering whether I can linke those .so files?

My code is as simple as

#include
#include
#include // only for direct call to ippiMedianFilter_8u_C3R!
#include

int main(int,char**)
{

cvUseOptimized(1); // load IPP
const char* opencv_libraries = 0;
const char* addon_modules = 0;
cvGetModuleInfo( 0, &opencv_libraries, &addon_modules );
printf( "OpenCV: %s\nAdd-on Modules: %s\n", opencv_libraries, addon_modules );

}

And,if I link the static library "libippcore.a" , I could get the program running:

OpenCV: cxcore: 1.1.0, cv: 1.1.0
Add-on Modules: libippcv.so, libippi.so, libipps.so, libippvm.so, libippcc.so

But, if I link the dynami library "libippcore.so", I failed to link the program as:

/usr/bin/ld: cannot find -lippcore

Can anybody give me a clue?

Best Regards

JIA

You have to use dynamic IPP libraries in OpenCV. This is OpenCV requirement. Please make sure you specfied linker where it should look for libraries
