			If you're installing FFTW v.2, you have the option of using MPI. I use [[OpenMPI]] for development on my laptop (alternatively, you can use [[LAM MPI]], but it's no longer being developed).

==Prerequisites==

==FFTW 3.2.2==

===Mac Snow Leopard (OS X 10.6)===

<source lang="bash">
#!/bin/sh

./configure \
--prefix=${HOME}/pkg/fftw/3.2.2 \
--enable-threads \
CC="gcc -arch i386 -arch x86_64" \

==FFTW 2.1.5==

./configure \
--prefix=${HOME}/pkg/fftw/2.1.5 \
--enable-threads \
--enable-mpi \
--with-mpi=${HOME}/pkg/openmpi/1.4.3 \

==Errors==

I saw the following error when I was attempting to use MPI compiler wrappers (mpicc, mpic++, etc.) that were part of my own [[OpenMPI]] build:

<pre>
checking for mpicc... mpicc
checking for MPI_Init... no
checking for MPI_Init in -lmpi... no
checking for MPI_Init in -lmpich... no
configure: error: couldn't find mpi library for --enable-mpi
</pre>

I fixed this by adding a library flag to my configure script:

<source lang="bash">
LDFLAGS="-L${HOME}/pkg/openmpi/1.4.3/lib/openmpi"
</source>
