--- Comment #28 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
I am trying to install a clean whizard-2.6.4 on x86_64-apple-darwin17, Xcode
9.4.1, SIP disabled, gfortran 8.2, ocaml 4.03.0. I got the following errors
with make check:

The later seems due to

*** FATAL ERROR:  Option '--logfile' needs a value

Is this expected?

What is the recommended way to change the fortran compiler?
