When I compile for MKL, I have the following in my Makefile
LIB_DIRS += -L/opt/intel/mkl/$(MKL_VER)/lib/$(MKL_ARCH)
INC_DIRS += -I/opt/intel/mkl/$(MKL_VER)/include
INC_DIRS += -I/opt/intel/mkl/$(MKL_VER)/include/fftw
LIB_FILES += -lpthread -lfftw3xc_intel -lmkl -lm
My include remains as #include <fftw3.h> but due to the new directory paths, it gets pointed to the Intel wrapper header.
Thank you man,
I have nearly the same makefile. The only difference is that I have
LIB_FILES +=
-lfftw3 -lmkl -lm
but even when I've change into -lfftw3xc_intel, still didn't work. I have something like this:
-------------------------------------------------------------------------------------------------

Thank you for your help.
Still, any ideas would be greatly appreciated.
