I am trying to build PIL for Win64 (x64, AMD64) (I am using Vista 64-bit). Appended are my notes on how I built and tested it (and the error messages). Any information on building a python Windows x64 extension (especially PIL) would help. Thanks
--------------- This is essential b/c I am using python ctypes to control a 64-bit dll (and ctypes must be 64-bit to do this, which means the python install must be 64-bit, which means the PIL install must be 64-bit). I am trying to build a binary compatible PIL with my (python for x64, on windows vista) install. http://docs.python.org/dist/module-distutils.msvccompiler.html Says that I should use the "Platform SDK" to compile Windows AMD64 extensions. So I installed "Microsoft Windows SDK", and compiled from the console x64 console. I tried both consoles (Release , default Debug): C:\Windows\System32\cmd.exe /E:ON /V:ON /T:0E /K "C:\Program Files\Microsoft SDKs\Windows\v6.0\Bin\SetEnv.Cmd" C:\Windows\System32\cmd.exe /E:ON /V:ON /T:0E /K "C:\Program Files\Microsoft SDKs\Windows\v6.0\Bin\SetEnv.Cmd" /x64 /Release I downloaded code for jpeg-6b, and compiled: * rename jconfig.vc to jconfig.h * nmake /f Makefile.vc I downloaded code for zlib123 (png/zip support), and compiled: * nmake /f win32/Makefile.msc These folders I put in "PIL\Imaging-1.1.6\libs_External\jpeg-6b" and "PIL\Imaging-1.1.6\libs_External\zlib123" I edited Imaging-1.1.6\setup.py: * os.environ['DISTUTILS_USE_SDK'] = "1" * os.environ['MSSdk'] = "1" * JPEG_ROOT = r"libs_External\jpeg-6b" * ZLIB_ROOT = r"libs_External\zlib123" I compiled with distutils: * setup.py clean * setup.py build_ext -i * setup.py build * setup.py install I ran "selftest.py" and I get the error: Traceback (most recent call last): File "C:\Downloads\Installs\python\PIL\Imaging-1.1.6\selftest.py", line 11, in <module> import ImageMath File "PIL\ImageMath.py", line 19, in <module> import _imagingmath ImportError: DLL load failed: A dynamic link library (DLL) initialization routine failed. I also tried to run python: >>> from PIL import Image >>> refImg = Image.open(r"sample.png") >>> refImg.getpixel((0,0)) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "PIL\Image.py", line 922, in getpixel self.load() File "PIL\ImageFile.py", line 155, in load self.load_prepare() File "PIL\PngImagePlugin.py", line 339, in load_prepare ImageFile.ImageFile.load_prepare(self) File "PIL\ImageFile.py", line 223, in load_prepare self.im = Image.core.new(self.mode, self.size) File "PIL\Image.py", line 36, in __getattr__ raise ImportError("The _imaging C module is not installed") ImportError: The _imaging C module is not installed Neither of my dll (_imaging.pyd and _imagingmath.pyd) files are getting loaded properly by python :-( _______________________________________________ Image-SIG maillist - Image-SIG@python.org http://mail.python.org/mailman/listinfo/image-sig
