Usage:
|
|
|
|
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>, <build_flib options>, <extra options>] <fortran files>
|
|
|
|
3) To generate signature files:
|
|
|
|
f2py -h <filename.pyf> ...< same options as in (1) >
|
|
|
|
Description: This program generates a Python C/API file (<modulename>module.c)
|
|
that contains wrappers for given fortran functions so that they
|
|
can be called from Python. With the -c option the corresponding
|
|
extension modules are built.
|
|
|
|
Options:
|
|
|
|
--2d-numpy Use numpy.f2py tool with NumPy support. [DEFAULT]
|
|
--2d-numeric Use f2py2e tool with Numeric support.
|
|
--2d-numarray Use f2py2e tool with Numarray support.
|
|
--g3-numpy Use 3rd generation f2py from the separate f2py package.
|
|
[NOT AVAILABLE YET]
|
|
|
|
-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>.
|
|
<fortran files> Paths to fortran/signature files that will be scanned for
|
|
<fortran functions> in order to determine their signatures.
|
|
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.
|
|
|
|
--[no-]wrap-functions Create Fortran subroutine wrappers to Fortran 77
|
|
functions. --wrap-functions is default because it ensures
|
|
maximum portability/compiler independence.
|
|
|
|
--include-paths <path1>:<path2>:... Search include files from the given
|
|
directories.
|
|
|
|
--help-link [..] List system resources found by system_info.py. See also
|
|
--link-<resource> switch below. [..] is optional list
|
|
of resources names. E.g. try 'f2py --help-link lapack_opt'.
|
|
|
|
--quiet Run quietly.
|
|
--verbose Run with extra verbosity.
|
|
-v Print f2py version ID and exit.
|
|
|
|
|
|
numpy.distutils options (only effective with -c):
|
|
|
|
--fcompiler= Specify Fortran compiler type by vendor
|
|
--compiler= Specify C compiler type (as defined by distutils)
|
|
|
|
--help-fcompiler List available Fortran compilers and exit
|
|
--f77exec= Specify the path to F77 compiler
|
|
--f90exec= 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
|
|
|
|
Extra options (only effective with -c):
|
|
|
|
--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.
|
|
|
|
-L/path/to/lib/ -l<libname>
|
|
-D<define> -U<name>
|
|
-I/path/to/include/
|
|
<filename>.o <filename>.so <filename>.a
|
|
|
|
Using the following macros may be required with non-gcc Fortran
|
|
compilers:
|
|
-DPREPEND_FORTRAN -DNO_APPEND_FORTRAN -DUPPERCASE_FORTRAN
|
|
-DUNDERSCORE_G77
|
|
|
|
When using -DF2PY_REPORT_ATEXIT, a performance report of F2PY
|
|
interface is printed out at exit (platforms: Linux).
|
|
|
|
When using -DF2PY_REPORT_ON_ARRAY_COPY=<int>, a message is
|
|
sent 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.
