I know, that "How to call Intel AVX based code with Intel IPP version 6.1"  recommends to create ipp_g9/e9.h headers manually, but it looks like an omission the tools/staticlib/ headers for Sandy Bridge are still not present in latest IPP 7.0 update 2...?
Could you also please clarify the status of px and mx cores in IPP 7.0?
In 7.0.2, the header file is similar with p8/w7 library, it need define it as g9 (32 bit), or e9 ( 64 bit) function:
#define ippgDFTFwd_CToC_10_32fc g9_ippgDFTFwd_CToC_10_32fc
#define ippgDFTFwd_CToC_10_64fc g9_ippgDFTFwd_CToC_10_64fc
