Multiple python 2.5 framworks
by Brian Granger Feb. 7, 2007

Feb. 7, 2007

Hi, We need to deploy a qt4 based python app and I am working on some of the build issues. Because we are using Qt, we need a framework build of Python (we are using 2.5). One of our requirements is that users can build and use the app without doing a system wide install. I am worried that our private python2.5 framework will conflict with the system wide python2.5 framework if it is installed. Can two python2.5 frameworks coexist on the same system. What are the potential issues and pitfalls? I can set the users paths to point to our python. I am mostly worried about building other python packages (using distutils) that we include in our app. How can I be sure that the various build processes won't pick up the system wide python2.5 framework? Thanks Brian

py2app ImportError
by Erwin Marsi Feb. 7, 2007

Feb. 7, 2007

My py2app-build application crashes with an ImportError. I'm using the standard python 2.5 framework from http://www.python.org/ download/ and py2app 0.3.5 build from sources. I followed the py2app tutorial and tried in alias mode first. Here's my setup.py: -- """ This is a setup.py script generated by py2applet Usage: python setup.py py2app """ from setuptools import setup APP = ['hitaext.py'] DATA_FILES = [] OPTIONS = {'argv_emulation': True} setup( app=APP, data_files=DATA_FILES, options={'py2app': OPTIONS}, setup_requires=['py2app'], ) -- My app runs fine. However, after building for deployment, running my app results in the following error: -- $ rm -rf build dist && python setup.py py2app ... $ dist/hitaext.app/Contents/MacOS/hitaext Traceback (most recent call last): File "/Users/erwin/Projects/Daeso/trunk/software/intern/hitaext/ dist/hitaext.app/Contents/Resources/__boot__.py", line 137, in <module> _run('hitaext.py') File "/Users/erwin/Projects/Daeso/trunk/software/intern/hitaext/ dist/hitaext.app/Contents/Resources/__boot__.py", line 134, in _run execfile(path, globals(), globals()) File "/Users/erwin/Projects/Daeso/trunk/software/intern/hitaext/ dist/hitaext.app/Contents/Resources/hitaext.py", line 17, in <module> from ielemtree import IndexElemTree File "/Users/erwin/Projects/Daeso/trunk/software/intern/hitaext/ dist/hitaext.app/Contents/Resources/lib/python2.5/ielemtree.pyc", line 11, in <module> ImportError: cannot import name ElementTree 2007-02-05 21:32:48.840 hitaext[4505] hitaext Error 2007-02-05 21:32:48.843 hitaext[4505] hitaext Error An unexpected error has occurred during execution of the main script ImportError: cannot import name ElementTree -- Any ideas on what went wrong and how to fix it? thanks, Erwin

Tkinter Question...
by Jerry LeVan Feb. 6, 2007

Feb. 6, 2007

Hi, I have recently upgraded my Mac to ActiveTCL from Tk Aqua. It appears that tcl/tk 8.4.14 works much more smoothly than apple's 8.4.0. I am trying to port some of my tcl stuff to python ( MacPython 2.4.3). I am using tkinter for the gui. It appears that tkinter.so is linked to the tk in /System/Library... (ie the old apple version) instead of the tk in /Library/Frameworks/ Tk.... This means that the interface is sorta clunky ie the window zoom buttons don't work, scroll controls in the lower right corner get covered up, scrolling and selection are a bit flakey... Is it possible to build tkinter against a more modern tk? If so, how? (Reading the forums at ActiveState on Python seems to indicate that ActiveStates tkinter for the Mac ( I have a G4) also links against the old Apple Tk.) Thanks, Jerry

problems with boost.python on OS X
by stephan nies Feb. 6, 2007

Feb. 6, 2007

Hello, has anyone used boost.python on OSX and can help me or point me to "hello world"-style example of a c++ - extension in boost.python that works on OSX. I have used boost.python on linux and am porting the app from linux to osx. Since the app uses a boost.python - extension module its essential for me to get the extension working. At the Moment everything compiles but i cant import the extension in python. I already posted on C++-sig but didn't get response so far. http://mail.python.org/pipermail/c++-sig/2007-February/011918.html My Situation: OS: PPC Mac OS X 10.4.8 Python: python-2.4.4-macosx2006-10-18.dmg from http://pythonmac.org/packages/py24-fat/dmg/ (this is a framework build) Boost: 1.33.1 build from source (./configure && make) i am building my extension by invoking: g++ -dynamic myextension.cpp -I/Library/Frameworks/Python.framework/Headers -I/System/Library/Frameworks/GLUT.framework/Headers -I/usr/include -I/Users/nies/src/boost_1_33_1 -c -o myextension.o and g++ -v -dynamiclib -framework Python -framework OpenGL -framework GLUT -L/Users/nies/src/boost_1_33_1/bin/boost/libs/python/build/libboost_python.dylib/darwin/release/shared-linkable-true/ -lboost_python-1_33_1 myextension.o -o myextension.dylib this compiles and when i try to import the extension in pythonw: Python 2.4.4 (#1, Oct 18 2006, 10:34:39) [GCC 4.0.1 (Apple Computer, Inc. build 5341)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import myextension Traceback (most recent call last): File "<stdin>", line 1, in ? ImportError: No module named myextension as far as i understand this is because python searches for .so files. when i symbolic-link myextension.so -> myextension.dylib and than try to import: Python 2.4.4 (#1, Oct 18 2006, 10:34:39) [GCC 4.0.1 (Apple Computer, Inc. build 5341)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import myextension Traceback (most recent call last): File "<stdin>", line 1, in ? ImportError: Inappropriate file type for dynamic loading so what am i doing wrong here? I would really appreciate some hints at this point. Thanks, Stephan

How to build Python 2.5 to support 64-bits on Mac OS X 10.4
by Dr. Harold Walter Schranz Feb. 1, 2007

Feb. 1, 2007

Hi Distinguished Pythoneers, Sorry if this Email is too verbose or unstructured ... (blame: blood sugar is dropping and I'm in need of some dinner!) I've been set the task of creating a 64 bit Intel build of Python 2.5 that supports the EM64T functionality in our research groups new machines which are both running OS X 10.4.8. Intel Core 2 Duo laptop: Machine Name: Mac Machine Model: MacBookPro2,2 Processor Name: Intel Core 2 Duo Processor Speed: 2.33 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per processor): 4 MB Memory: 2 GB Bus Speed: 667 MHz Xserve Quad Xeon: Machine Name: Xserve Machine Model: Xserve1,1 Processor Name: Dual-Core Intel Xeon Processor Speed: 3 GHz Number Of Processors: 2 Total Number Of Cores: 4 L2 Cache (per processor): 4 MB Memory: 16 GB Bus Speed: 1.33 GHz The usual Python 2.5 build (http://www.python.org/ftp/python/2.5/ python-2.5-macosx.dmg) I believe is just 32 bit Universal ... we don't need a Universal build but 32 bits just doesn't cut it (the proverbial mustard) so to speak. I believe just a command line Python would be fine that supports 64 bit (as we need to interface to a MySQL database with multi-gigabytes of data). So far we've tried a source base build (http://www.python.org/ftp/ python/2.5/Python-2.5.tgz) 1) with the default configure (default options) which just leads to a 32 bit Intel python executable: $ file python.exe python.exe: Mach-O executable i386 2) and then a few different flags on configure (I've no idea where my "partner in crime" got these from! I though -march was the new flag!): /configure OPT="-fast -Wall \ > -Wstrict-prototypes -fno-common -fPIC \ > -isysroot /Developer/SDKs/MacOSX10.4u.sdk \ > -arch x86_64" \ > LDFLAGS="-Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk,\ > -headerpad_max_install_names -arch x86_64" While the configure runs ... the make eventually fails with: /Developer/SDKs/MacOSX10.4u.sdk/System/Library/Frameworks/ CoreServices.framework/Frameworks/CarbonCore.framework/Headers/fp.h: 1338: error: 'SIGDIGLEN' undeclared here (not in a function) make: *** [Python/mactoolboxglue.o] Error 1 I've seen this SIGDIGLEN error about before ... probably relates to the conditional in fp.h not handling an unknown CPU_TARGET : #if TARGET_CPU_PPC || TARGET_CPU_X86 #define SIGDIGLEN 36 #elif TARGET_CPU_68K #define SIGDIGLEN 20 #endif Anyway, I expect the fundamental problem relates to Carbon not being 64-bit ready (until Leopard). I guess I just want to do a basic ("Unix-"-y) command line build of Python 2.5 that handles the EM64T functionality in the chips we have in our machines. Do I have to wait until Leopard??? Thanks for any pointers (or any other structures 8-) ). Harry. Extinguished Pythoneer (temporarily) ------------------------------------------------------------------------ ---- Dr. Harold W.
