Intel 17 compilers should be fine.
What arguments did you give to configure? Does the configure script
indicate that it is using the MKL version of FFTW? Can you post the
config.h script that you got? If it's like mine, it should have no
references to ...amber18/lib/libfftw3.a, and should only point to MKL.
But it sounds like your config.h script is different than mine.

Dave's suggestion of using GNU compilers first is a good one: be sure to
start from a fresh directory. At the end of the configure step, you can
use "nm" to examine /home/SEBOMD/amber18/lib/libfftw3.a to see if has
symbols like fftw_alloc_real (etc) in it. Also check its date: it
should have just been freshly made.
