FFTW formula has no options

(Argel Ramírez Reyes) #1

Using OS X 10.14.4 Mojave.

From the formula page (https://formulae.brew.sh/formula/fftw)

Appears that this formula should have the option:

--with-mpi

However the option is not recognized, and

brew options fftw doesn’t show anything.

does this mean that now it uses mpi by default?

Thanks!

If you look at that page, you’ll see that fftw depends on open-mpi, so MPI is used by default.

It also doesn’t specify that it should have the option, just that people tried to install it using that option recently.

Ok.

Right, I saw the dependency, I didn’t see that implication.

It seems weird that people try to install it with an option that does not exist. I was following the tutorial for the dedalus project here
https://dedalus-project.readthedocs.io/en/latest/machines/mac_os/mac_os.html
I understand now that the output of the formulas page doesn’t reflect the options of the formula.

Thanks

Given that it points to macOS 10.9, which is from almost 6 years ago. I wouldn’t trust that to be up to date. Options were removed from homebrew-core last year so it’s at least out of date on that respect.
