For future reference, I discovered: (a) that PETSc builds FFTW by default, and further (b) PETSc has all the parallel FFT stuff implemented as a MATFFTW matrix class with wrappers in petsc4py. So all that conversation was unnecessary, sorry! ________________________________ From: Lawrence Mitchell <wencel@gmail.com> Sent: 24 May 2020 18:32 To: Cotter, Colin J <colin.cotter@imperial.ac.uk> Cc: firedrake <firedrake@imperial.ac.uk> Subject: Re: [firedrake] Firedrake compatible C compiling

OK, new question!
How do I ask PETSc to build FFTW via the Firedrake install script?
Do PETSC_CONFIGURE_OPTIONS="--download-fftw=1" firedrake-install --normal-arguments Lawrence
