This problem ate up quite a but of time, and apparently people have faced it before but the solution wasn't there anywhere. My problem was linked to script selection. Once you download the Intel IPP library and follow the steps the readme from C:/ipp-samples/speech-codecs/readme.htm you have to select between *ia32*and *intel64*. In my case the choice wasn't obvious because my Windows Vista is 32-bit while I have a 64-bit Intel core i5. The rule is that unless both the OS and the architecture is 64-bit, you have to use ia32. The confusion was mainly because the *build_intel64* script was successful, while the *ia32 *script was failing for most components. Only the speech-codecs component is of interest to us here. After that there should be the speech.lib under C:\ipp-samples\speech-codecs\_bin\ia32_cl10\lib and you're good to go. There might still be issues with respect to some libraries not being found. So just add the missing ones to *Properties -> Linker -> General -> Additional Library Directories* and *Properties -> Linker -> Input-> Additional Dependencies* and it ought to work fine. The rest of the steps are well documented. Feel free to mail me in case of issue, I will try my best to help. > Today's Topics: > > 1.
