Symptom(s): For example, Build Simple_player Sample:
Run build32.sh of ../ipp-samples/audio-video-codecs, two of the sample projects fails: The log files for both projects list similar errors. For simple_player, the errors is:
/usr/bin/ld: warning can't open dynamic library: libippcore-5.3.dylib referenced from: /Library/Frameworks/Intel_IPP.framework/Versions/5.3/em64t/Libraries/libippac.dylib (checking for undefined symbols may be affected) (No such file or directory, errno = 2) /usr/bin/ld: warning can't open dynamic library: libguide.dylib referenced from: /Library/Frameworks/Intel_IPP.framework/Versions/5.3/em64t/Libraries/libippac.dylib (checking for undefined symbols may be affected) (No such file or directory, errno = 2) /usr/bin/ld: Undefined symbols: _ippGetCpuType referenced from libippac-5 expected to be defined in libippcore-5.3.dylib collect2: ld returned 1 exit status
The environment was set correctly and the libraries are in the correct place.
Cause:
The ippAC libraries were bound to frameworks on Mac OS*X incorrectly. Two shell scripts to unbind and then rebind the IPP to the framework fix the problem.
Solution:
The solution is for IPP 5.3 Update 1:
- Please make sure IPP 5.3 Update 1 installed. (the installed package is m_ipp_p_5.3.1.056)
- Please download the fixed scripts from ippbind.zip, copy the "ippbind.sh" and "ippunbind.sh" into the directory where IPP installed (e.g /Library/Frameworks/Intel_IPP.framework) and change them in executatable file
$chmod +x ippbind.sh $chmod +x ippunbind.sh
- With "root" account,cd into directory where IPP installed (e.g /Library/Frameworks/Intel_IPP.framework),
run ippunbind.sh script first to unbind IPP library to Framework. Then run ippbind.sh script to bind IPP library to Framework. $ cd /Library/Frameworks/Intel_IPP.framework $ ./ippunbind.sh SUCCESSFULLY $ ./ippbind.sh SUCCESSFULLY
- Enter the directory where your application are in, e.g,
[optional Step ]run IPP 5.3 update1 environment first, $ cd ../ipp-samples/audio-video-codecs $ . /Library/Frameworks/Intel_IPP.framework/Versions/5.3.1.056/ia32/tools/env/ippvars.sh then build the sample, $ ./build32.sh
The fix is available in IPP 5.3 update 2.
