Hi, I'm trying to get started with f2py on a Windows 7 environment using the Python(x,y) v 2.6.5.6 distribution. I'm following the introductory example of the f2py userguide and try to wrap the file FIB1.F using the command: f2py.py -c fib1.f -m fib1 from the windows command line. I get the following output: running build running config_cc unifing config_cc, config, build_clib, build_ext, build commands --compiler opti ons running config_fc unifing config_fc, config, build_clib, build_ext, build commands --fcompiler opt ions running build_src build_src building extension "fib" sources f2py options: [] f2py:> c:\users\thomas\appdata\local\temp\tmpamyxnx\src.win32-2.6\fibmodule.c creating c:\users\thomas\appdata\local\temp\tmpamyxnx creating c:\users\thomas\appdata\local\temp\tmpamyxnx\src.win32-2.6 Reading fortran codes...

Running f2py without arguments result in the following version information: Version: 1 numpy Version: 1.5.1 Requires: Python 2.3 or higher. License: NumPy license (see LICENSE.txt in the NumPy source code) Copyright 1999 - 2005 Pearu Peterson all rights reserved. http://cens.ioc.ee/projects/f2py2e/ I'm puzzled by this, I expect I have the compiler correctly installed, since f2py recognizes it (and I am able to compile Fortran code using GCC from Eclipse). How about the f2py version number = 1? I was under the impression that development had reached version >2. Reinstalling Numpy from SourceForge numpy-1.5.1-win32-superpack-python2.6.exe result in exactly the same output as above. Trying to install f2py using easy_install and then running f2py without arguments result in the following error: Traceback (most recent call last): File "C:\Python26\Scripts\f2py.py", line 5, in <module> pkg_resources.run_script('f2py==2.45.241-1926', 'f2py.py') File "C:\Python26\lib\site-packages\pkg_resources.py", line 489, in run_script self.require(requires)[0].run_script(script_name, ns) File "C:\Python26\lib\site-packages\pkg_resources.py", line 1207, in run_scrip t execfile(script_filename, namespace, namespace) File "c:\python26\lib\site-packages\f2py-2.45.241_1926-py2.6-win32.egg\EGG-INF O\scripts\f2py.py", line 3, in <module> import f2py2e File "C:\Python26\lib\site-packages\f2py-2.45.241_1926-py2.6-win32.egg\f2py2e\ __init__.py", line 10, in <module> import f2py2e File "C:\Python26\lib\site-packages\f2py-2.45.241_1926-py2.6-win32.egg\f2py2e\ f2py2e.py", line 26, in <module> import crackfortran File "C:\Python26\lib\site-packages\f2py-2.45.241_1926-py2.6-win32.egg\f2py2e\ crackfortran.py", line 1586 as=b['args'] ^ SyntaxError: invalid syntax Any comments on how to adapt my setup to allow f2py to function correctly would be much appreciated!
