# ----------------------------------------------------------------------
# Makefile for OpenMM Preview Release 4 workshop "hello world" examples.
# August 18, 2009
# See https://simtk.org/home/openmm.
# ----------------------------------------------------------------------
# This assumes you have gcc compilers for whatever language you are
# using: g++ for C++ and C, gfortran for Fortran 95.
#
# For the C and Fortran examples, we're depending on your version of
# OpenMM to have been built with the automatically-generated API
# wrappers.
#
# This has had only minimal testing, although it has been known to
# work. It is likely to work fine for C and C++. For Fortran, you
# may need to add some of the C/C++ libraries:
# -lc -lm -lstdc++ (or -lstdc++.6) -lgcc -lgcc_s
# but this wasn't required for these examples on Centos 5.2 using
# gcc 4.1.2.
# Check whether this is the right capitalization for your install directory.
OpenMM_INSTALL_DIR=/usr/local/openmm
CFLAGS = -g
FFLAGS = -g -ffree-line-length-none
# Extra libraries required when gfortran links with a C++ module.
# If this doesn't work, look in /usr/lib to
# see what versions of libstdc++.so you have and try different
# versions.
