make.inc.macosx_gcc-8

# Makefile variable overrides for Mac OSX compilation with GCC v.8.*
#
# Use this if you'll need to link against gfortran.
#
# Copy this file to make.inc, and if needed edit for your setup.

# By default we use clang/LLVM (which is aliased to /usr/lib/gcc, etc).
# This make.inc is if you want to override this.
# Get gcc from brew then use, eg:
CXX=g++-8
CC=gcc-8
FC=gfortran

# (compile flags for use with GCC are as in linux makefile)
CFLAGS +=

# If you're getting warning messages of the form:
#    ld: warning: object file (lib-static/libfinufft.a(finufft1d.o)) was built for
#    newer OSX version (10.13) than being linked (10.9)
# Then you can uncomment the following two lines with the older version number
# (in this example -mmacosx-version-min=10.9)
#
#CFLAGS += "-mmacosx-version-min=<OLDER OSX VERSION NUMBER>"

# as in makefile, but with the brew /usr/local/ stuff...

# OpenMP with GCC on OSX needs following...
OMPFLAGS = -fopenmp
OMPLIBS = -L/usr/local/lib -lgomp

# MATLAB interface:
# some of these will depend on your FFTW library location...

MEX = $(shell ls -d /Applications/MATLAB_R20**.app)/bin/mex
# Also see docs/install.rst for possible edits to MATLAB's MEX XML file.

# If you have segfault of MATLAB then please try the following:
#MOMPFLAGS = -D_OPENMP
#OMPFLAGS = -Xpreprocessor -fopenmp
#OMPLIBS = $(shell ls -d /Applications/MATLAB_R20**.app)/sys/os/maci64/libiomp5.dylib
# This links to MATLAB's omp not gomp.
