F2py + g95 + mingw + windows configuration and use

F2py is used to create interfaces so that python can call the FORTRAN program. It supports many Fortran compilers, such:

Absoft, Lahey, IBM, gfortran, and g95.

F2py is now part of numpy.

1. Install python25

Create distutils. cfg in C:/python25/lib/distutils

[Build]

Compiler = mingw32

2. Install mingw

3. Install g95

When compiling a FORTRAN program, g95 sometimes prompts that files such as crt2.o cannot be found, so you need to configure g95:

Copy g95/lib/*. O *. A to g95/lib/GCC-lib/i686-pc-mingw32/4.0.4

4. f2py application example

A) create a FORTRAN file HW. F with the following content:

Program hwtest

Real * 8 R1, R2, S

R1 = 1.0

R2 = 0.0

S = hw1 (R1, R2)

Write (*, *) 'hw1, result: ', S

End

Function hw1 (R1, R2)

Real * 8 R1, R2

Hw1 = sin (R1 + R2)

Return

End

B) cmd

C) f2py-m hw-c hw. f

HW. PYD is generated in the directory.

D) Python

>>> Import HW

>>> HW. hw1 (1, 0)
