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

General Information

Today == Saturday, October 25, 2008

With special thanks for many of The Keys to frank and [http://boodebr.org/main/python/build-windows-extensions his blog]. Also, an [http://www.ibm.com/developerworks/linux/library/l-cppeak3.html?ca=dgr-lnxw03PythonEggWithSetuptools 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): attachment: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

  • Devel (group)

    • gcc (3.4.4-3)
    • gcc-core (3.4.4-3) (should auto-select)
    • gcc-g++ (3.4.4-3) (should auto-select)
    • gcc-mingw (20040810-1)
    • gcc-mingw-core (20050522-1) (should auto-select)
    • gcc-mingw-g++ (20080522-1) (should auto-select)
    • make (3.81-2)
    • SWIG (1.3.36-1)

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

  • File

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

  • C:\Program Files\Python25

(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

  • python ez_setup.py

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

  • {{{version_re = re.compile(r'^(\d+) \. (\d+) (\. (\d+))? ([ab](\d+))?$',

}}} to

  • {{{version_re = re.compile(r'^(\d+) \. (\d+) (\. (\d+))? (\. (\d+))?$',

}}}

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):

  • File "setup.py", line 1, in <module>

    • from setuptools import setup, Extension

ImportError: No module named setuptools}}}

Usage Notes

{{{Python 2.5.2 (r252:60911, Feb 21 2008, 13:11:45) [MSC v.1310 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import magic}}}

magic1.dll Not in Path

FIRST: Windows msgbox with red-X icon and [OK] button: 

  TITLE: python.exe - Unable To Locate Component

  TEXT: This application has failed to start because magic1.dll was not found. Re-installing the application may fix this problem.

THEN (back in interpreter): {{{Traceback (most recent call last):

  • File "<stdin>", line 1, in <module> File "build\bdist.win32\egg\magic.py", line 2, in <module> File "build\bdist.win32\egg\cmagic.py", line 5, in <module> File "build\bdist.win32\egg\_cmagic.py", line 7, in <module> File "build\bdist.win32\egg\_cmagic.py", line 6, in bootstrap

ImportError: DLL load failed: The specified module could not be found.}}}

  • NOTE: This is the same exact message (inside interpreter, NOT a Windows msgbox) that shows when I tried to use Py v2.6.

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

NOTE: magic1.dll file MUST BE FINDABLE IN THE PATH!!!
