Hello friends, I was able to successfully build PJSIP 1.8.10 on MacOS and make my first VoIP app for iphone. However, now I'm trying to add some additional audio codecs such as AMR and G729 through out Intel IPP last release, and despite of using http://trac.pjsip.org/repos/wiki/Intel_IPP_Codecs instructions I always get myself into an dead end. I downloaded the IPP examples and compile speech_codecs/ folder using: ./build_ia32.sh gcc4 and all PASSED then using the ./configure --enable-ipp --with-ipp=$IPPROOT --with- ipp-examples=$IPPSAMPLES with: export IPPROOT=/opt/intel/composerxe-2011.2.142/ipp and export IPPSAMPLES=~/Desktop/ipp-samples it breaks checking IPP Usability, and looking into the config.log details, I find a line saying that -lippsr can't be found. I really don't know what to do next, I have tried some others arguments, but not luck. Intel IPP version is 7.0.* if anyone can give me a hand I'll appreciated. Thanks in advance Ernesto
