Recently, I'm investigating the DCT4 module in IPP. The manual says all of the DCT4 functions are deprecated. I believe they should be available by linking IPP library until they are dropped in the future release.
But it seems that the linker cannot find the DCT4 functions in IPP. It says following on my mac, by clang:
Undefined symbols for architecture x86_64:
"_ippgDCT4_32f", referenced from:
_DLB_fft_open in ffttest.dlb_dsplib_fft_test_osx_amd64_clang_ipp_float_interleaved_release.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
My IPP version is:
#define IPP_VERSION_MAJOR 7
#define IPP_VERSION_MINOR 0
#define IPP_VERSION_BUILD 205
#define IPP_VERSION_STR "7.0"
I've also searched in ipps.h. I cannot find any prototype declaration of DCT4 function.
My question is, have they been removed already?
