The Makefile.lammps file in this directory is used when building
LAMMPS with its PYTHON package installed. The file has several
settings needed to compile and link LAMMPS with the Python library.
You should choose a Makefile.lammps.* file compatible with your system
and your version of Python, and copy it to Makefile.lammps before
building LAMMPS itself. You may need to edit one of the provided
files to match your system.
If you create a new Makefile.lammps file suitable for some version of
Python on some system, that is not a match to one of the provided
Makefile.lammps.* files, you can send it to the developers, and we can
include it in the distribution for others to use.
The default Makefile.lammps will automatically choose the default
python interpreter of your system and will infer the flags from
the python-config utility, that is usually bundled with the python
installation. If needed, you can copy one of the other provided
Makefile.lammps.* files to to Makefile.lammps before building
LAMMPS itself.
To illustrate, these are example settings from the
Makefile.lammps.python2.7 file:
The files Makefile.lammps.python2 and Makefile.lammps.python3 are
similar to the default file, but meant for the case that both,
python 2 and python 3, are installed simultaneously and you want
to prefer one over the other. If neither of these files work, you
may have to create a custom Makefile.lammps file suitable for
the version of Python on your system. To illustrate, these are
example settings from the Makefile.lammps.python2.7 file:
python_SYSINC = -I/usr/local/include/python2.7
python_SYSLIB = -lpython2.7 -lnsl -ldl -lreadline -ltermcap -lpthread -lutil -lm
python_SYSPATH =
python_SYSPATH =
PYTHON=python2.7
python_SYSINC refers to the directory where Python's Python.h file is
found. LAMMPS includes this file.

PYTHON is the name of the python interpreter. It is used for
installing the LAMMPS python module with "make install-python"
