Problem packaging vtk application on Snow Leopard with py2app
by jens.thomas＠stfc.ac.uk May 26, 2010

May 26, 2010

Hi, I'm trying to package up an app under OSX 10.6 (MacBook with Intel Duo) with py2app. The application uses the external modules: vtk, numpy, Pmw. When I try to package it up, I get the following error: ...lots of output... Copying /Library/Python/2.6/site-packages/numpy-1.4.1-py2.6-macosx-10.6-universal.egg/numpy/version.pyc -> /Users/jmht/Documents/ccp1gui/dist/ccp1gui.app/Contents/Resources/lib/python2.6/numpy creating /Users/jmht/Documents/ccp1gui/dist/ccp1gui.app/Contents/Resources/lib/python2.6/lib-dynload/vtk Traceback (most recent call last): File "/Library/Python/2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/build_app.py", line 589, in _run self.run_normal() File "/Library/Python/2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/build_app.py", line 660, in run_normal self.create_binaries(py_files, pkgdirs, extensions, loader_files) File "/Library/Python/2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/build_app.py", line 777, in create_binaries platfiles = mm.run() File "build/bdist.macosx-10.6-universal/egg/macholib/MachOStandalone.py", line 101, in run for fn in platfiles: File "build/bdist.macosx-10.6-universal/egg/macholib/util.py", line 227, in iter_platform_files if is_platform_file(fn): File "build/bdist.macosx-10.6-universal/egg/macholib/util.py", line 206, in is_platform_file header = mach_o.fat_header.from_fileobj(fileobj, _endian_='>') File "build/bdist.macosx-10.6-universal/egg/macholib/ptypes.py", line 44, in from_fileobj return cls.from_str(f.read(cls._size_), **kw) File "build/bdist.macosx-10.6-universal/egg/macholib/ptypes.py", line 48, in from_str return cls.from_tuple(struct.unpack(endian + cls._format_, s), **kw) error: unpack requires a string argument of length 8 As py2app kindly fires up the debugger, I was able to look through the stack and see that: endian + cls._format_ is '>LL' (i.e. big-endian with two unsigned longs) the string s that was read in from the file is: '\xca\xfe\xba\xbe\x00\x00\x00\x02\x00\x00\x00\x07\x00\x00\x00\x03' which is of length 16, and cls._size_ is 16. Everything points to 16 being the correct length, but the call to struct.unpack is expecting something of length 8. I looked in the struct module and there is a 'calcsize' function which indicates what size is required for a specific format. struct.calcsize('>LL') is 8 whereas struct.calcsize('LL') is 16 so it looks to me like the problem is with the format string. Does anyone know if this is a bug in py2app, python or just something I'm doing wrong? Any help/suggestions would be appreciated. Thanks, Jens -- Scanned by iCritical.

PIL binaries -- please test
by Christopher Barker May 25, 2010

May 25, 2010

Hi folks, Much to my surprise, I had a little time to build some PIL binaries: http://dl.dropbox.com/u/855965/PIL-OSX-Binaries/PIL-1.1.7-py2.5-macosx10.5.… http://dl.dropbox.com/u/855965/PIL-OSX-Binaries/PIL-1.1.7-py2.6-macosx10.5.… I'd really like folks to test them on as many different systems as possible. You can see these are for python 2.5 or 2.6, build with and for the python.org python binaries. They should have all dependencies statically linked. I built them on OS-X 10.5 (leopard), so they may not work on 10.4 I'd love if someone could test and see if they do, however, I no longer have a 10.4 system to test on. I do expect them to work on 10.5 and 10.6, PPC and Intel. Please let me know if you test, whether it worked or not, and on what system/python. If these work well, I think Fredrik will put them on the PIL site.

DESTDIR problem
by Chris Kees May 25, 2010

May 25, 2010

Hi, I'm having trouble with 'make install' trying to put or touch a few things in /Applications even though I've set the prefix and framework directories to be $MY_PREFIX as in ./configure --prefix=${MY_PREFIX} --enable-framework=${MY_PREFIX} --disable-universalsdk MACOSX_DEPLOYMENT_TARGET=10.6 When running 'make install' I get: OSError: [Errno 13] Permission denied: '/Applications/Python 2.6/Build Applet.app/Contents/Info.plist' Is there some additional option I need to set to MY_PREFIX to get everything where I want it? Thanks, Chris

Hi, I'm compiling python and readline from source and getting a segmentation fault in readline after two lines of input. Anybody seen this before or know the fix?

Possible bug in setuptools/py2app
by jens.thomas＠stfc.ac.uk May 25, 2010

May 25, 2010

Hi, I've hit a problem trying to package up an application using py2app (this is on OSX 10.6). This is using the latest version of py2app as installed with easy_install. My setup.py file lives in the top-level directory of the project directory (i.e. it's in the same directory as the python code for the project, which I think is a valid place for it to live). When I try and package it up with py2app, the packaging fails because the paths to the data files that py2app looks for have the first character of their path lopped off and py2app crashes out as shown below: running py2app running build_py creating build/bdist.macosx-10.6-universal/lib/ccp1gui/oc error: can't copy 'oc/ccp1gui.zme.txt': doesn't exist or not a regular file The correct path should be: "doc/ccp1gui.zme.txt" I've managed to trace the problem to the file: /System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/setuptools/command/build_py.py specifically the function _get_data_files, where there is the code: # Length of path to strip from found files plen = len(src_dir)+1 In my case, src_dir is blank for the first package directory (I think because it's the same one as the one in which setup.py is running from), which is why it chops off the first character. Is this a bug? Many thanks, Jens -- Scanned by iCritical.

python 2.7 Tkinter using Tk 8.6
by Stephen M. Gava May 24, 2010

May 24, 2010

Hi there, I've installed the python.org package of python 2.7b2 for osx snow leopard. It's Tkinter appears to be built against Tk 8.4, but I want to use Tkinter with my installed framework build of Tk 8.6 (for native Tk .png support among other things). So, I assume I need to build my own osx packages of 2.7 linking against Tk 8.6 to achieve this? Thanks, Stephen

Could py2app bundle all the requirements of my package?
by cool-RR May 23, 2010

May 23, 2010

Hello! I'm developing a desktop application called GarlicSim: http://garlicsim.org I want to distribute it natively to all OSes. On Windows I have already succeeded packaging it with py2exe and InnoSetup. I have not touched py2app yet. Do you think that py2app could bundle all the packages I want? I want to bundle the entire Python standard library. (My program is a sort of a science lab, and a very important part of it is a Python shell that I provide, and I want my users to be able to use all of Python.) I want to bundle wxPython and cairo. (I'm especially worried about cairo.) My app is wxPython-based and I want to use cairo for drawing widgets. I want to bundle a big selection of scientific modules. Scipy, numpy, Traits, Mayavi (With VTK, which is especially hard to install.) Pretty much most of the things that Enthought provides. Note that with py2exe I've been able to do all of the above, (except I haven't finished bundling all the scientific libraries, just most of them.) (And no, I don't mind my app weighing 1GB.) Will py2app be able to bundle all these things and how much hair will I have left on my head after I get it working? (Please `cc` any replies to me.) Thanks for your help, Ram Rachum.

Py2APP App Won't Run After Build
by Mike May 22, 2010

May 22, 2010

Hi, I built my program with py2app thew standard way. py2applet --make-setup zgp.py then python setup.py py2app. As far as external packages I'm using WXPython, PyGame, and Pyttsx. I think the error is something related to Pyttsx. Here's the output I get when running the app from the console: Xelabos-Mac-Pro:src MacAdmin$ ./dist/zgp.app/Contents/MacOS/zgp Traceback (most recent call last): File "/Users/MacAdmin/Desktop/RSG/zgp/src/dist/zgp.app/Contents/Resources/__boot__.py", line 137, in <module> _run('zgp.py') File "/Users/MacAdmin/Desktop/RSG/zgp/src/dist/zgp.app/Contents/Resources/__boot__.py", line 134, in _run execfile(path, globals(), globals()) File "/Users/MacAdmin/Desktop/RSG/zgp/src/dist/zgp.app/Contents/Resources/zgp.py", line 18, in <module> main() File "/Users/MacAdmin/Desktop/RSG/zgp/src/dist/zgp.app/Contents/Resources/zgp.py", line 13, in main output.setup() File "output.pyc", line 36, in setup File "build/bdist.macosx-10.6-universal/egg/pyttsx/__init__.py", line 39, in init File "build/bdist.macosx-10.6-universal/egg/pyttsx/engine.py", line 45, in __init__ File "build/bdist.macosx-10.6-universal/egg/pyttsx/driver.py", line 64, in __init__ ImportError: No module named drivers.nsss 2010-05-21 07:08:28.986 zgp[41405:10b] zgp Error 2010-05-21 07:08:29.443 zgp[41405:10b] zgp Error An unexpected error has occurred during execution of the main script ImportError: No module named drivers.nsss

May 21, 2010

hi, i have to work with mac OS 9.2 for legacy reasons...is there a compiled version of python for this os ? i need to get input about variable values from the user and then print out some text files that make use of this input. a gui would be nice, but keyboard based input would be ok too... thanks much, suresh ps. if there isn't a version of python that will work, perhaps you could suggest some other scripting language for 0S 9.2 ?

My previous Message

May 19, 2010

Sorry about my previous message. It seems the guy who's testing this for me forgot to install Py2app. It built successfully...I think I'm now getting an import error: no module named Drivers.NSSS. I'll post more console output if there is any. Mike
