Hi Ian,
I deleted the Cactus directory and re- downloaded using Homebrew. After running ./simfactory/bin/sim setup --optionlist=osx-homebrew.cfg --runscript generic-mpi.run
I checked the simfactory/mdb/optionlists/osx-homebrew.cfg which had the following lines
CPP = cpp-6
FPP = cpp-6
CC = gcc-6
CXX = g++-6
F90 = gfortran-6
CPPFLAGS =
FPPFLAGS = -traditional
CFLAGS = -g -std=c11
CXXFLAGS = -g -std=c++14
F90FLAGS = -g -m128bit-long-double -fcray-pointer -ffixed-line-length-none
LDFLAGS = -lgfortran
(see attached)
I did not edit anything
I ran ./simfactory/bin/sim build --mdbkey make 'make -j2' --thornlist=manifest/einsteintoolkit.th
and got the following output
