Py2App Problem
by Mike May 20, 2010

May 20, 2010

Hi, I was finally able to get my app to run by using multiprocessing, so thanks guys for that suggestion. However, I'm trying to build it with py2app, and am getting this error. I generated a setup.py script using py2applate --make-setup zgp.py.

Still Unable to get my Python program working on the mac
by Mike May 19, 2010

May 19, 2010

Hi, I'm sure you've seen my thread that started off with a module import problem. Now, I've really hit a dead end since the program won't even stay open and there's no traceback to give me a starting point. Could someone who's experienced in python mac development and has some extra time be willing to look at my app and try to help me figure this out? I'd be willing to give the SVN info, just email me off list. The project I'm working on will bring accessible games to blind mac users, so I'd greatly appreciate it if someone would help out, and it would help a lot of people as well. Thanks in advance. Mike

Trying to find a .def file
by Monte Milanuk May 16, 2010

May 16, 2010

Hello all, I'm trying to setup an extension to idle (vidle) and the instructions talk about a file 'config-extensions.def'. The author works primarily on a PC and I'm obviously working on a Mac (Python 2.6.5, if it matters). I've tried searching the entire hard drive for this file, but only turned up two results: one file as part of the Sage installation, and another as part of a vpython installation (both installed out of curiosity rather than any need/use). So at this point I'm kind of unsure as to how to proceed? Any suggestions? TIA, Monte

Python 2.7b2
by Ronald Oussoren May 13, 2010

May 13, 2010

Hi, As you might know the second beta of python 2.7 was released last weekend. This is the first beta with macosx installers, they can be downloaded from <http://www.python.org/download/releases/2.7/> There are two installers: one for OSX 10.3 or later and one for OSX 10.5 later. The "10.3" installer includes support for 32-bit CPUs, while the "10.5" one supports 64-bit intel code as well. Ronald P.S. The "10.3" installer is simular to the installers for previous releases and works on 10.5/10.6 as well.

py2app and zlib
by Guillaume VIRY May 12, 2010

May 12, 2010

Hello everyone I'm trying to package an application with py2app on Snow Leopard, but I can't even build a Hello Word application. I installed Python26 via MacPorts, as well as py2app and pyselect with all their dependencies. I switch my default Python to the MacPorts one. So far everything seems fine and the application works perfectly in the console. Then, problem. When I try to run the built application: 5/8/10 9:05:55 AM [0x0-0x2e62e6].org.pythonmac.unspecified.toto[73116] zipimport.ZipImportError: can't decompress data; zlib not available 5/8/10 9:05:55 AM toto[73116] toto Error 5/8/10 9:05:55 AM toto[73116] toto Error An unexpected error has occurred during execution of the main script ZipImportError: can't decompress data; zlib not available 5/8/10 9:05:58 AM com.apple.launchd.peruser.501[111] ([0x0-0x2e62e6].org.pythonmac.unspecified.toto[73116]) Exited with exit code: 255 After further verification, zlib.so is in the built package. And an "import zlib" works in my python console. Could anyone help me with this ? I'm out of ideas :(

Module Import Problem
by Mike May 11, 2010

May 11, 2010

Hi, My friend is testing my program for me on his Mac, he's running Snow leopard. I'm using a package called Pyttsc that allows for text to speech on the Mac. He's getting the following error: file: build/bdist.macosx-10.6universal/egpyttsx/drivers/nsss.py, line 18: no module named foundation I looked into this, and it seems to be something related to PyObjC. However, he tried import pyobjc and got no errors. Any idea what the problem might be and how to fix it? Also, will this application build with py2app since it uses this package? Thanks. Mike

Problems with Tk (I think)
by Jan Erik Moström May 7, 2010

May 7, 2010

I'm new to Tk so it might be something that I might be doing wrong but I have a crash that I can't find the cause to. The error message I get on the crash is: python(19468,0x7fff70f5cbe0) malloc: *** error for object 0x1002c5a10: double free *** set a breakpoint in malloc_error_break to debug Abort trap This is using the standard 2.6.1 version on OS X 10.6.3, but version 2.5 give the same result. When I try this using a linux box (v2.5.2) the program runs as it should. I tried to using the debugger to single step through the critical lines and it seem to crash when it should return from a menu item handler. The code for that handler looks like this def saveToFile(self): filename = dlg.asksaveasfilename() self._storage.store(filename,self._win.getText()) Single stepping seem to indicate that the call to self._win.getText() works just fine, the store command saves some text to a file and the file is created with the correct text, but then something seem to happen: (Pdb) s --Return-- > /Users/jem/Desktop/testing.py(96)saveToFile()->None -> self._storage.store(filename,self._win.getText()) (Pdb) s 2010-05-06 15:40:54.806 Python[19589:d07] *** __NSAutoreleaseFreedObject(): release of previously deallocated object (0x1011466f0) ignored Does anyone have an idea what could be causing this? The complete code is available at <http://tmp.myownsnapshots.com/pyproblem> (and yes, I know that the code looks a bit strange but I have my reasons :) - jem

extensions not loading
by Amos Anderson May 6, 2010

May 6, 2010

hello -- i'm trying to embed python in my software so that i don't have to worry about which version clients have installed. this is causing lots of random errors on OSX 10.6.3, but appears to work just fine on linux... here's as far as I've gotten... 1) I added this to my Jamroot: using python : 2.6 : python/bin/python2.6 : python/include/python2.6 : python/lib/python2.6/config : ; 2) I downloaded python 2.6.5 .tar.bz2 and put it in my source tree. I've added these steps to my Makefile: tar -xjf $(PYTHON_DIR)/Python-2.6.5.tar.bz2 -C $(PYTHON_DIR) ./configure --prefix=$(CURDIR)/$(PYTHON_DIR) make && make install cp $(PYTHON_DIR)/lib/python2.6/config/libpython2.6.a $(PYTHON_DIR)/lib/python2.6/config/libpython2.6.dylib where the last step seemed necessary because OSX requires a dynamic library, and if it doesn't find one, it will link to the system's framework version instead, which is a different version of python. 3) Patched my python according to this bug (because _environ wasn't being included if i'm not building a framework, thanks Ronald for finding this for me) http://bugs.python.org/issue1602133 4) Compiles & links with no errors or warnings. Paths all appear to be ok when I do bjam -d2 5) Inspecting my build (to make sure everything is 64 bit): > lipo -detailed_info libboost_python.dylib input file libboost_python.dylib is not a fat file Non-fat file: libboost_python.dylib is architecture: x86_64 > lipo -detailed_info libpython2.6.dylib input file libpython2.6.dylib is not a fat file Non-fat file: libpython2.6.dylib is architecture: x86_64 > lipo -detailed_info python input file python is not a fat file Non-fat file: python is architecture: x86_64 > otool -L libboost_python.dylib libboost_python.dylib: libboost_python.dylib (compatibility version 0.0.0, current version 0.0.0) /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.1) (should I see libpython2.6.dylib listed here????) 6) Running my code: $trunk/src/python/bin/python -v myscript.py .... Fatal Python error: Interpreter not initialized (version mismatch?) ../triad.sh: line 19: 56200 Abort trap $trunk/src/python/bin/python -v $@ 7) Trying to force load my library: setenv DYLD_INSERT_LIBRARIES /Users/amos/triad/trunk/src/python/lib/python2.6/config/libpython2.6.dylib $trunk/src/python/bin/python -v myscript.py dyld: could not load inserted library: /Users/amos/triad/trunk/src/python/lib/python2.6/config/libpython2.6.dylib Trace/BPT trap 8) I tried this: ./configure --enable-universalsdk --with-universal-archs=intel --prefix=$(CURDIR)/$(PYTHON_DIR) and it didn't work either. next up, i'll figure out the framework issue here: http://bugs.python.org/issue3646 so i can try that option too. amos.

python library missing _environ symbol
by Amos Anderson May 5, 2010

May 5, 2010

i'm having trouble with my non-standard way of building python. what I want to do is bundle Python-2.6.5.tar.bz2 with my software, so that the version i want can be built along with my code, which might happen on osx or linux etc. part of my software includes C++ extensions w/ boost, so my build system needs to link to the correct local version of python. here's (one of) the problem i've run into. ./configure --enable-universalsdk --with-universal-archs=intel then building my project I get: Undefined symbols: "_environ", referenced from: _initposix in libpython2.6.dylib(posixmodule.o) (maybe you meant: cstring=ignore_environment) ld: symbol(s) not found collect2: ld returned 1 exit status ...failed darwin.link.dll boost/boost_1_42_0/bin.v2/libs/python/build/darwin-4.2.1/release-triad/libboost_python.dylib... and sure enough: > nm libpython2.6.a | grep environ nm: no name list U _environ now, i can get _environ if I do it this way: ./configure --enable-framework --enable-universalsdk --with-universal-archs=intel > nm libpython2.6.a | grep environ nm: no name list 0000000000025768 b _environ so it appears to be the case that the _environ symbol is included if --enable-framework is added to the configure options, but is undefined if --enable-framework is not added. now, if I were actually planning on installing this in /Library/Frameworks/ then this behavior would be ok. however, because i want to treat my python install in an OS agnostic way, I don't want to use the --enable-framework option. is there another way to do this? i'm not enthusiastic about monkeying around in Python-2.6.5.tar.bz2 and then zipping it back up again, but if that's the only way then so be it... it seems to be the case that configure has some setting that's triggered with frameworks, so if someone could help me figure out how to trigger that setting in a more general context, then that might be the easiest thing to do. thanks! amos.
