I had a try to upgrade IPP version from IPP 7.1 to 8.0.1. Two issues were found.
1) According to http://software.intel.com/en-us/forums/topic/391419, new function ippsDFTInit_C_32f was added in IPP 8.0. That's good. However, there's still no function ippsDFTGetSize_C_32f available. Even I find it seems to work by using ippsDFTGetSize_C_32fc instead. However, that's not ideal from my understanding.
2) The redistribute library names are changed. In previous version, the library names are like libippac_l.a, libipps_l.a and libippcore_l.a. However, they are changed to libippac.a, libipps.a and libippcore.a. Since the library name are fixed in Makefile, it doesn't work if we don't add a symbolic link to them. Why did that happen? Is it possible to fix it in future release?
