mfpymake 1.2.10

pymake is a Python package to compile MODFLOW-based models.

pymake

Python package for building MODFLOW-based programs from source files.

Version 1.2.10

This is a python package for compiling MODFLOW-based and other Fortran, C, and C++ programs. The package determines the build order using a directed acyclic graph and then compiles the source files using GNU compilers (gcc, g++, gfortran), Clang compilers (clang, clang++), or the Intel compilers (ifort, icl, icc, mpiifort).

pymake can be run from the command line or it can be called from within python. By default, pymake sets the optimization level, Fortran flags, C/C++ flags, and linker flags that are consistent with those used to compile MODFLOW-based programs released by the USGS.

Note that if gfortran is used to compile MODFLOW-based codes, the openspec.f and FILESPEC.inc (MT3DMS) files will automatically be changed to the following so that binary files are created properly using standard Fortran:

c -- created by pymake.py
CHARACTER*20 ACCESS,FORM,ACTION(2)
DATA ACCESS/'STREAM'/
DATA FORM/'UNFORMATTED'/
DATA (ACTION(I),I=1,2)/'READ','READWRITE'/
c -- end of include file

Command Line Usage

When pymake is installed, a mfpymake (or mfpymake.exe for Windows) program is installed.mfpymake can be used to compile MODFLOW 6 from source files located on your computer directly from the command line using the Intel Fortran compiler ifort from the root directory containing the src subdirectory by specifying:

mfpymake src/ mf6 -mc --subdirs -fc ifort

To see help for running from command line, use the following statement.

mfpymake -h

The help message identifies required positional arguments and optional arguments that can be provided to override default values.

usage: mfpymake [-h] [-fc {ifort,mpiifort,gfortran,none}] [-cc {gcc,clang,clang++,icc,icl,mpiicc,g++,cl,none}] [-ar {ia32,ia32_intel64,intel64}] [-mc] [-dbl] [-dbg] [-e] [-dr] [-sd] [-ff FFLAGS]
                [-cf CFLAGS] [-sl {-lc,-lm}] [-mf] [-md] [-cs COMMONSRC] [-ef EXTRAFILES] [-exf EXCLUDEFILES] [-so] [-ad APPDIR] [-v] [--keep] [--zip ZIP] [--inplace] [--networkx] [--meson] [--mesondir]
                srcdir target

This is the pymake program for compiling fortran, c, and c++ source
files, such as the source files that come with MODFLOW. The program
works by building a directed acyclic graph of the module dependencies
and then compiling the source files in the proper order.

positional arguments:
  srcdir                Path source directory.
  target                Name of target to create. (can include path)

options:
  -h, --help            show this help message and exit

  -sd, --subdirs        Include source files in srcdir subdirectories. (default is None)
  -ff FFLAGS, --fflags FFLAGS
                        Additional Fortran compiler flags. Fortran compiler flags should be enclosed in quotes and start with a blank space or separated from the name (-ff or --fflags) with a equal sign

  -cf CFLAGS, --cflags CFLAGS
                        Additional C/C++ compiler flags. C/C++ compiler flags should be enclosed in quotes and start with a blank space or separated from the name (-cf or --cflags) with a equal sign

  -sl {-lc,-lm}, --syslibs {-lc,-lm}
                        Linker system libraries. Linker libraries should be enclosed in quotes and start with a blank space or separated from the name (-sl or --syslibs) with a equal sign (-sl='-libgcc').

  -ef EXTRAFILES, --extrafiles EXTRAFILES
                        List of extra source files to include in the compilation. extrafiles can be either a list of files or the name of a text file that contains a list of files. (default is None)

  --meson               Use meson to build executable. (default is False)
  --mesondir            meson directory. (default is '.')

Note that the source directory should not contain any bad 
or duplicate source files as all source files in the source 
directory, the common source file directory (srcdir2), and 
the extra files (extrafiles) will be built and linked. 
Files can be excluded by using the excludefiles command 
line switch.

Examples:

Compile MODFLOW 6 from the root directory containing the 
source files in subdirectories in the src/ subdirectory:

$ mfpymake src/ mf6 --subdirs

Compile MODFLOW 6 in the bin subdirectory using the Intel 
Fortran compiler from the root directory containing the source 
files in subdirectories in the the src/ subdirectory:

$ mfpymake src/ mf6 --subdirs -fc ifort --appdir bin

Note that command line arguments for Fortran flags, C/C++ flags, and syslib libraries should be enclosed in quotes and start with a space prior to the first value (-ff ' -O3') or use an equal sign separating the command line argument and the values (-ff='-O3'). The command line argument to use an -O3 optimization level when compiling MODFLOW 6 with the ifort compiler would be:

mfpymake src/ mf6 -mc --subdirs -fc ifort -ff='-O3'

From Python

Script to compile MODFLOW 6

When using the pymake object (Pymake()) only the positional arguments (srcdir, target) need to be specified in the script.

import pymake

pm = pymake.Pymake()
pm.srcdir = '../src'
pm.target = 'mf6'
pm.include_subdirs = True
pm.build()

It is suggested that optional variables required for successful compiling and linking be manually specified in the script to mininimize the potential for unsuccessful builds. For MODFLOW 6, subdirectories in the src subdirectory need to be included and 'pm.include_subdirs = True' has been specified in the script. Custom optimization levels and compiler flags could be specified to get consistent builds.

Non-default values for the optional arguments can specified as command line arguments. For example, MODFLOW 6 could be compiled using Intel compilers instead of the default GNU compilers with the script listed above by specifying:

python mymf6script.py -fc ifort -cc icc

Automatic Download and Build

When pymake is installed, a make-program (or make-program.exe for Windows) program is installed. make-program can be used to build MODFLOW 6, MODFLOW-2005, MODFLOW-NWT, MODFLOW-USG, MODFLOW-LGR, MODFLOW-2000, MODPATH 6, MODPATH 7, GSFLOW, VS2DT, MT3DMS, MT3D-USGS, SEAWAT, and SUTRA. Utility programs CRT, Triangle, and GRIDGEN can also be built. make-program downloads the distribution file (requires an internet connection), unzips the file, sets the pymake settings required to build the program, and compiles the program from the source files. Optional pymake command line arguments can be used to customize the build (-fc, -cc, --fflags, etc.). For example, MODFLOW 6 could be built using intel compilers and an O3 optimization level by specifying:

make-program mf6 -fc=ifort --fflags='-O3'
