f2py usage problem

[bkamrani]

Hi Python gurus,
I have installed numpy and interested in testing f2py module using the
first example in the documentation.

First I tried:

C:\test>python "C:\Program Files\Python25\Scripts\f2py.py" -c fib1.f

installed,
you can try compiling with MingW32, by passing "-c mingw32" to
setup.py.
Then I installed mingw32 and tried to pass "-c mingw32" to setup.py as
below, but got another error:

**config)
TypeError: setup() got multiple values for keyword argument 'version'

Version (as printed out to be "2_4422") doesn't look like to be
multiple value as the message says...
I have tried different machine with different python version
installation (2.5, 2.4) and also searched the forum without finding my
answer.

Is there anybody out there so kind as to help me with this?
Thanks...

Hi,

You will want to ask numpy questions on the numpy mailing list.

http://www.scipy.org/Mailing_Lists

First I tried:

C:\test>python "C:\Program Files\Python25\Scripts\f2py.py" -c fib1.f

....

running build_ext

That's not the setup.py it is talking about. f2py is used both as a program and
a library inside your own distutils setup.py scripts. Internally, the f2py
program uses distutils to build the extension module. The error message you see
comes from distutils, so it is (confusingly, in this case) assuming you are
calling distutils from a setup.py script.

The corresponding f2py program option would be --compiler=mingw32 . See "f2py
-h" for all of the command line options.
