f2py − Fortran to Python interface generator
(1) To construct extension module sources:
f2py [<options>] <fortran files> [[[only:]||[skip:]] <fortran functions> ] [: <fortran files> ...]
(2) To compile fortran files and build extension modules:
f2py -c [<options>, <config_fc options>, <extra options>] <fortran files>
(3) To generate signature files:
f2py -h <filename.pyf> ...< same options as in (1) >
This program generates a Python C/API file (<modulename>module.c) that contains wrappers for given Fortran or C functions so that they can be called from Python. With the −c option the corresponding extension modules are built.
−h <filename>
Write signatures of the fortran routines to file <filename> and exit. You can then edit <filename> and use it instead of <fortran files>. If <filename>==stdout then the signatures are printed to stdout.
<fortran functions>
Names of fortran routines for which Python C/API functions will be generated. Default is all that are found in <fortran files>.
|
skip: |
Ignore fortran functions that follow until ’:’. |
|||
|
only: |
Use only fortran functions that follow until ’:’. |
|||
|
: |
Get back to <fortran files> mode. |
−m <modulename>
Name of the module; f2py generates a Python/C API file <modulename>module.c or extension module <modulename>. Default is ´untitled´.
−−[no−]lower
Do [not] lower the cases in <fortran files>. By default, −−lower is assumed with −h key, and −−no−lower without −h key.
−−build−dir <dirname>
All f2py generated files are created in <dirname>. Default is tempfile.mktemp().
−−overwrite−signature
Overwrite existing signature file.
−−[no−]latex−doc
Create (or not) <modulename>module.tex. Default is −−no−latex−doc.
−−short−latex
Create ’incomplete’ LaTeX document (without commands \documentclass, \tableofcontents, and \begin{document}, \end{document}).
−−[no−]rest−doc
Create (or not) <modulename>module.rst. Default is −−no−rest−doc.
−−debug−capi
Create C/API code that reports the state of the wrappers during runtime. Useful for debugging.
−include´<includefile>´
Add CPP #include statement to the C/API code. <includefile> should be in the format of either ’"filename.ext"’ or ’<filename.ext>’. As a result <includefile> will be included just before wrapper functions part in the C/API code. The option is depreciated, use ’usercode’ statement in signature files instead.
−−[no−]wrap−functions
Create Fortran subroutine wrappers to Fortran 77 functions. −−wrap−functions is default because it ensures maximum portability/compiler independence.
−−help−link [..]
List system resources found by system_info.py. [..] may contain a list of resources names. See also −−link−<resource> switch below.
−−quiet
Run quietly.
−−verbose
Run with extra verbosity.
|
−v |
Print f2py version ID and exit. |
−−include_paths path1:path2:...
Search include files (that f2py will scan) from the given directories.
The following
options are effective only when −c switch is used.
−−help-compiler
List available Fortran compilers [DEPRECIATED].
−−fcompiler=<name>
Specify Fortran compiler type by vendor.
−−compiler=<name>
Specify C compiler type (as defined by distutils)
−−fcompiler-exec=<path>
Specify the path to F77 compiler [DEPRECIATED].
−−f90compiler−exec=<path>
Specify the path to F90 compiler [DEPRECIATED].
−−help−fcompiler
List available Fortran compilers and exit.
−−f77exec=<path>
Specify the path to F77 compiler.
−−f90exec=<path>
Specify the path to F90 compiler.
−−f77flags="..."
Specify F77 compiler flags.
−−f90flags="..."
Specify F90 compiler flags.
−−opt="..."
Specify optimization flags.
−−arch="..."
Specify architecture specific optimization flags.
−−noopt
Compile without optimization.
−−noarch
Compile without arch-dependent optimization.
−−debug
Compile with debugging information.
The following
options are effective only when −c switch is used.
−−link-<resource>
Link extension module with <resource> as defined by numpy_distutils/system_info.py. E.g. to link with optimized LAPACK libraries (vecLib on MacOSX, ATLAS elsewhere), use −−link−lapack_opt. See also −−help−link switch.

-DPREPEND_FORTRAN -DNO_APPEND_FORTRAN -DUPPERCASE_FORTRAN
-DUNDERSCORE_G77
Macros that might be required with non-gcc Fortran compilers.
-DF2PY_REPORT_ATEXIT
To print out a performance report of F2PY interface when python exits. Available for Linux.
-DF2PY_REPORT_ON_ARRAY_COPY=<int>
To send a message to stderr whenever F2PY interface makes a copy of an array. Integer <int> sets the threshold for array sizes when a message should be shown.
Python 1.5.2 or higher (2.x is supported).
Numerical Python 13 or higher (20.x,21.x,22.x,23.x are supported).
Optional Numarray 0.9 or higher partially supported.
