Hi Justin!
I had the same problem and I used your advise but I am not sure if this
entirely worked for me...
I used:
cmake -DGMX_MPI=ON DCMAKE_INSTALL_PREFIX=$HOME/gromacs
-DFFTWF_INCLUDE_DIR=$HOME/fftw/include
-DFFTWF_LIBRARY=$HOME/fftw/lib/libfftw3f.so -DCMAKE_PREFIX_PATH=$HOME/fftw/
..
The use of -DCMAKE_PREFIX_PATH eliminates the need for -DFFTWF_INCLUDE_DIR and
-DFFTWF_LIBRARY. Not that this is the source of your problem, but you can
certainly trim down your command.
and I got:
-- checking for module 'fftw3f'
-- found fftw3f, version 3.2.2
-- Looking for fftwf_plan_r2r_1d in
/home/users/didymos/fftw/lib/libfftw3f.so
-- Looking for fftwf_plan_r2r_1d in
/home/users/didymos/fftw/lib/libfftw3f.so - found
-- Looking for fftwf_have_simd_avx in
/home/users/didymos/fftw/lib/libfftw3f.so
-- Looking for fftwf_have_simd_avx in
/home/users/didymos/fftw/lib/libfftw3f.so - not found
-- Looking for fftwf_have_simd_sse2 in
/home/users/didymos/fftw/lib/libfftw3f.so
-- Looking for fftwf_have_simd_sse2 in
/home/users/didymos/fftw/lib/libfftw3f.so - found
So it seems ok but I am not sure about first two lines:
-- checking for module 'fftw3f'
-- found fftw3f, version 3.2.2
it should be 3.3.3
Is there a different FFTW installed anywhere else on your system? I believe the
first "found fftw3f" statement comes from pkgconfig detection, but this is
superseded by what you specify manually. Perhaps someone who is more familiar
with this element of the build system can comment.
