Help with PIL on 64 bit Windows 7 and Maya

[Andrew_Seymour]

Hi,

I've integrated PIL into some of our tools for Maya. In particular I use it to create 16bit TIFFs.

In Maya 2010 64 bit which I believe uses Python 2.6.1 everything worked fine. I got compiled versions of PIL from: http://www.lfd.uci.edu/~gohlke/pythonlibs/
which worked great.

I'm now preparing to move to the latest version of 64bit Maya which I believe uses Python 2.6.4.

I'm having problems with importing the _imaging module.

With the path added to the system path I first got this error:

# Error: ImportError: file <maya console> line 7: DLL load failed: The specified module could not be found. #

I then used dependency walker to try and find out what was missing. I then tried to include a 64 bit version of msvcr90.dll in the PIL directory.
This resulted in the following error:

# Error: ImportError: file <maya console> line 1: DLL load failed: A dynamic link library (DLL) initialization routine failed. #

Windows Error:

Microsoft Visual C++ Runtime Errror!
R6034
An application has made an attempt to load the C runtime library incorrectly.
Please contact the application's support team for more information.



Looking a little deeper PIL worked fine in 64 bit with Python 2.6.4 that I installed for windows from the python site:
Installed:        Python 2.6.4 (r264:75708, Oct 26 2009, 07:36:50) [MSC v.1500 64 bit (AMD64)] on win32

But, with Maya the compiled python included looks slightly different:
Maya:                Python 2.6.4 (r264:75706, May 19 2011, 13:53:43) [MSC v.1600 64 bit (AMD64)] on win32

Would this be the reason behind the issues, and if so is there a process I can follow to fix it?


I personally don't have the know how or software to compile PIL locally as I am a Technical Artist and not a fully blown programmer, so any help would be greatly appreciated.

Can you help or advise?

Dear Andrew,

apparently the new version of Maya includes a custom version of Python,
which is built with the Visual Studio 2010 compiler (version 16) and the
MSVCR10 C runtime library. The standard CPython 2.6 distribution, and
almost all existing extension package binaries, use the Visual Studio
2008 compiler and the MSVCR90 C runtime library.

The correct solution would be to build PIL with the Visual Studio 2010
compiler and link against the custom python26.lib from Maya.

As a workaround you could try to provide an external msvcr90 manifest
file for the existing PIL pyd extensions. This might not work correctly
because the use of different C runtime libraries in one process can
cause crashes or memory corruptions.
