I play a bit with Cython on Windows7 and a get this problem:
When a compile with minwg32 ( installed like this: http://wiki.cython.org/InstallingOnWindows ) this is work with Blender 32bits but not with 64bit. I normal I think.
For that a check to compile cython extension like that: http://wiki.cython.org/64BitCythonExtensionsOnWindows . With Windows SDK C/C++ compiler I be able to compile 32bit and 64bit cython extension and it’s work really fine with externally installed pyhton ! But it’s not work at all with embedded python in blender ( error message about not found library if I remember ).
-6Gig of ram
-Windows7 home edition OEM
-Python 3.2.2 32bit and 64bit ( from python.org )
-Official 2.62 Blender release 32bit and 64bit ( from blender.org )
-Windows SDK for Windows 7 (GRMSDKX_EN_DVD.iso from Microsoft website)
-MinWG32 (from winwg.org)
If I do a short story: Minwg32 work great but just in 32bit version of Blender. Windows SDK C/C++ Compiler don’t work at all ( 32bit and 64bit) with Blender but works with externally installed python (from python website). Cython website said to not use Winwg64 , for this reason I don’t try it.
Somebody have a idea and already successfuly compiled cython extension for Blender 64bit ?
