General Information

Today == Saturday, October 25, 2008

With special thanks for many of The Keys to frank and his blog. Also, an IBM article on setuptools had the info that helped me (at least) "install" setuptools without easy_install. (Necessary Today for Py v2.6; see below.)

I tried with Python v2.6, but could not get it to work; I'm still not familiar with the magic of eggs, distutils, setuptools, etc. If anyone has the fix(es), let me know and I'll retest, revise, and update this info! (FYI: The problem is it's acting as if it can't find magic1.dll; if v2.6 is uninstalled, v2.5[.2] is [re-]installed, all works A-OK.)

This is my NON-PRISTINE copy of SWIG-able python-magic, unless/until Mr. Hupp re-posts it to his site (see below): LARZ-python-magic-v0.1-c112ac064b7f.zip

NOTE: Mr. Hupp is working on a newer version; thus, all of this may become depreciated...

This is what I did. It works on (32-bit) Windows XP Pro, SP3, on an old Athlon system with <=512MB.

As they say: Your Mileage May Vary... :)

Software Used/Needed

CygWin

version 2.573.2.3

http://www.cygwin.com/

May setup with all default settings, except MUST ADD

GnuWin32 - (Magic) "File" Utility

version 4.26 (more recent than what was available via CygWin Today)

http://gnuwin32.sourceforge.net/packages/file.htm

http://downloads.sourceforge.net/gnuwin32/file-4.26-setup.exe

May setup with defaults, except (I recommend) change install directory from

to simply

NOTE: It's already set to install below "Program Files"

Python

version 2.5.2

http://python.org/ftp/python/2.5.2/python-2.5.2.msi

Installed with all default settings EXCEPT install-to path

(Python) setuptools

version 0.6c9

http://pypi.python.org/pypi/setuptools

As of Today there wasn't a pre-built .EXE installer for Python 2.6 (which I'd TRIED to test with first, to no avail), SO had to "hack" a bit - see IBM article link, above, for some info... simply grab

and run

Otherwise, if an installer is avail for your ver of Py, use it! :)

python-magic

version '0.1' (c112ac064b7f) with/for SWIG

http://hupp.org/adam/hg/python-magic

NOTE: Adam (Hupp) doesn't have the SWIG version posted any longer; my copy isn't "pristine"; anybody have one lying around to send me? :)

Configuration & Changes

C:\Program Files\Python25\Lib\distutils

distutils.cfg

must have thiw file, with at least

{{{[build] compiler = mingw32}}}

version.py

Due to newer CygWin, change line 100 from

}}} to

}}}

Do The Installation Shuffle

Go to where you've put the python-magic source files, then:

{{{path=%PATH%;C:\Program Files\Python25;C:\cygwin\bin;C:\Program Files\File\bin

python setup.py install}}}

Examples of Output You Might See

No setuptools

{{{Traceback (most recent call last):

ImportError: No module named setuptools}}}

UNSUCCESSFUL build, due to no distutils.cfg compiler=mingw32 "fix"

Successful Import/Use

{{{>>> import magic >>> test = magic.Magic() >>> test.from_file( '\\cygwin\\bin\\which.exe' ) 'PE32 executable for MS Windows (console) Intel 80386 32-bit'}}}

Magic (Compiled) Files Not in Path/Elsewhere

{{{>>> import magic >>> test = magic.Magic( magic_file = 'C:\\magic' ) # NOTE: This is the full path+filename of the magic db file >>> test.from_file( '\\startrek.exe' ) 'MS-DOS executable, MZ for MS-DOS'}}}

File Location Information

DEFAULT/ASSUMED LOCATION FOR MAGIC DATABASE FILES IS C:\Program Files\File\share\file
