makefile

# Linux/OSX makefile for spharm-interp MEX compilation.
# cut down from 2015 version, Aug 2022, Alex Barnett.

# ===== system-dependent settings : please adjust =====
FC = gfortran
FFLAGS = -O3 -march=native -std=legacy

# No openmp (single-core):
#OMPFLAGS =
#OMBLIBS =
# Or use following for openmp: (OSX may instead need link to libiomp5.so)
OMPFLAGS = --openmp
OMPLIBS = -lgomp

# Linux users, set this to your mex executable (eg in MATLAB source tree):
MEX = mex
# Mac users should use something like this:
#MEX = /Applications/MATLAB_R2014a.app/bin/mex
# Or for Octave use
#MEX = mkoctfile --mex

# Linux users:
MEXFLAGS = -largeArrayDims -lgfortran -lm $(OMPLIBS)
# Mac users use this:
#MEXFLAGS = -largeArrayDims -L/usr/local/gfortran/lib -lgfortran -lm
