Error on Windows 7 64 bits about python-magic HOT 13 CLOSED

Reading this thread is a weird experience since I'm having a similar but off in important ways experience. I get the "not a valid Win32 application" error when I run it in 32-bit Python, not 64-bit as you seem to.

Unfortunately, when I run things in 64-bit Python I get this:

>>> magic.from_file(r'H:\tmp\1508161', True)
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    magic.from_file(r'H:\tmp\1508161', True)
  File "C:\code_python-magic\python-magic\magic.py", line 131, in from_file
    m = _get_magic_type(mime)
  File "C:\code_python-magic\python-magic\magic.py", line 119, in _get_magic_type
    i = instances.__dict__[mime] = Magic(mime=mime)
  File "C:\code_python-magic\python-magic\magic.py", line 55, in __init__
    self.cookie = magic_open(self.flags)
WindowsError: exception: access violation writing 0x0000000000000001

I should add that I've got those 64-bit cygwin dlls in the system32 folder, renamed, etc.

No idea. Maybe you're not allowed to use 32-bit dlls in a 64-bit build of python? Not very familiar with window development.

Works when i use a 32bit version of Python

from python-magic.

Same here. On 64-bit CPU. 64-bit python 2.7.3 is a no-go. 32-bit python works.

from python-magic.

so what's the solution for this? I'm using Win 8 and 64-bit python 2.7 and I don't want to just go back to 32-bit Python (my other libraries would fail)

from python-magic.

Windows does not allow loading 32-bit dlls into a 64-bit process and vice-versa. I've not been able to find any 64-bit builds of libmagic online, so I think you'll need to do your own build of libmagic etc.

I've added this to the "Troubleshooting" section of README.md

Hi,

please: ¿where I can fond file 64 bits?

me too need this DLL, thanks

from python-magic.

Resolved this by installing the 64-bit version of Cygwin (http://cygwin.com/install.html) and copying the following list of DLLs from <your-cygwin64-path>\bin to C:\Windows\System32:

• cygwin1.dll
• cygz.dll
• cygmagic-1.dll (Don't forget to rename it to magic1.dll)

from python-magic.

Awesome, thanks. Rudolfs, would you mind checking the update here to see if it makes sense for cygwin users?

Hi!

I currently don't have the means to test it, but it seems like the update is alright and should work.

On a side note;
If I understand correctly, you started this project back in 2001.
There now appear to be official python bindings for libmagic https://github.com/glensc/file/tree/master/python
(Haven't had the chance to compare, though)

from python-magic.

This project and those bindings have been in parallel development (neither knowing about the other) for a long time. It's problematic because they share the same module name. I'd like to ultimately merge this in with the file distribution and mark those as deprecated, but haven't gotten around to doing it.

Thanks @rvikmanis and @ahupp for help with this ... worked for me on Windows 7 x64. Though you don't need to rename the cygmagic-1.dll to magic1.dll anymore due to update fc73c30c2fd4d17babfd1a7b864c96ba517f6130[fc73c30]
