I was wondering if any one has experience compiling FFTW-2.1.5 with icc 11.1.046. When I run the ./configure script with the following flags I get the message: 'configure: error: don't know how to enable OpenMP'.
./configure --enable-mpi --enable-threads --with-openmp --prefix=
Now I *think* I just need to add the -openmp flag to icc to enable this. Does anyone know how I can tell the configure script that openmp can be enabled with this compiler flag? The script just dies when when it can't figure out openmp.
Also, it complains about not being able to use the following compiler flags:
-fno-schedule-insns -fschedule-insns2 -fstrict-aliasing
From looking through the icc documentation it looks as though -fstrict-aliasing can be replaced with the -ansi-alias flag. I am not sure what to do to replace the other flags.
