Shell login for py2app bundle
by Dan Ross March 19, 2010

March 19, 2010

I'm trying to call Imagemagick's convert through a subprocess from within a bundled app. Console.app is telling me that it can't find it in /bin/sh which stands to reason. I can change the "convert" command to "/usr/local/bin/convert" in the app but then when convert calls Ghostscript (gs) it can't find IT in /bin/sh. Suggestions? Thanks, Dan

Installing PIL
by Henning Hraban Ramm March 18, 2010

March 18, 2010

Ahoi, since there was no appropriate binary package/egg for Python 2.6 on OSX 10.4/PPC, I tried to compile from source but did run into some dependency problems: PIL took some libs from my MacPorts installation (/opt/local/) that were incompatible to some it took from the OSX SDKs, and it couldn't find libraries that were installed with X11 (XQuartz 2.5.0 on x.org 1.7.6). I just changed the include paths in setup.py, and this order works best for me: elif sys.platform == "darwin": add_directory(library_dirs, "/usr/local/lib") add_directory(library_dirs, "/usr/X11R6/lib/") add_directory(include_dirs, "/usr/X11R6/include") add_directory(library_dirs, "/Developer/SDKs/MacOSX10.4u.sdk/usr/lib") add_directory(include_dirs, "/Developer/SDKs/MacOSX10.4u.sdk/usr/include") add_directory(library_dirs, "/Developer/SDKs/MacOSX10.3.9.sdk/usr/lib") add_directory(include_dirs, "/Developer/SDKs/MacOSX10.3.9.sdk/usr/include") add_directory(library_dirs, "/opt/local/lib") add_directory(include_dirs, "/opt/local/include") HTH someone else. Greetlings, Hraban

Fun with py2app and OpenGL
by R Fritz March 15, 2010

March 15, 2010

Explicitly including packages 'photom' (mine) and 'OpenGL' (published) produces strange results when py2app is run. For some reason, instead of ending up in the site-packages.zip file, or the site-packages directory, the packages are dropped into ../site-packages.zip, where they are not found. I ended up hacking this by creating site-packages and moving the packages into it, but am still wondering why it doesn't just work. Is there a simple fix I am missing? -- Randolph Fritz design machine group, architecture department, university of washington rfritz(a)u.washington.edu -or- rfritz333(a)gmail.com setup.py: """ This is a setup.py script generated by py2applet Usage: python setup.py py2app """ from setuptools import setup APP = ['PhotomView.py'] DATA_FILES = [] INCLUDES = ['ctypes.util'] PACKAGES = ['photom','OpenGL'] RESOURCES = ['PhotomView.xrc'] OPTIONS = { 'argv_emulation': True, 'includes': INCLUDES, 'packages': PACKAGES, 'resources' : RESOURCES } setup( app=APP, data_files=DATA_FILES, options={'py2app': OPTIONS}, setup_requires=['py2app'], )

Minor bug/typo in r89 (trunk) of py2app/build_app.py
by Brant Faircloth March 12, 2010

March 12, 2010

hello, i was working out of the trunk for py2app in hopes of building a pyqt4 app, and after updating to r32 of macholib (and fixing the 'unpack requires a string argument of length with…' error), i set about returning to py2app to get things working. anyway, on my renewed building efforts, the macholib error was fixed, but i got: NameError: global name 'PYTHONFRAMEWORK' is not defined /Library/Python/2.6/site-packages/py2app-0.4.4-py2.6.egg/py2app/build_app.py(893)copy_framework() -> if info['shortname'] == PYTHONFRAMEWORK: digging around, i noticed a typo in the global variable name of the current trunk for py2app. this is likely fixed somewhere, but see attached patch if it isn't (it's terribly simple ; ). best, brant < * ) (_ \\ _ ||

I should have added: If you're happy with 32-bit Python on Snow Leopard and have no need to build from source, just do as Chris recommended earlier: Use Python.org's installer. It is built on an earlier OS than SL and links against Apple's Tcl/Tk 8.4, so when you install it on SL, it finds the 8.4 version that Apple includes in SL for backward compatibility. -Tom ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/

Ned- No need to apologize; I realize the Python developers are juggling many balls right now! But I'll apologize---for always replying in a way that starts yet another thread. I reply to emails or web archive versions of the posts, and as far as I can tell, there is no way to respond in a manner that continues a thread. I've looked for info on this, and from what I can tell it's a capability that is being considered for *future* Mailman web interfaces. If anyone knows of a way to accomplish this right now, please let me know. Regarding my setup.py hack to allow building 32-bit on 10.6 with Tcl/Tk 8.4: > The last time I played with the 10.6 Tk 8.4, it worked just fine, so, > yeah, if you only need a 32-bit Tk on 10.6 that should be OK. Just to clarify: I think the situation is a little worse than some may infer from this. As I understand things, if you want to build Python 2.6 on 10.6 with a working Tkinter and IDLE, and without installing a new Tcl/Tk, your only option is build a 32-bit Python that links against Apple's Tcl/Tk 8.4, and this cannot be done with the existing installer. I just want other readers not to infer from your comment that if you're happy with Python's default 64-bit build, all is fine. If you are willing to install a new Tcl/Tk, you can have success but you have to be careful. Both ActiveTcl 8.4 and 8.5 (the current version) will produce a working IDLE. Both of these are only 32-bit in the free versions, so you will have to do some undocumented installation trickery (in my earlier post) to build a 32-bit Python-2.6 on 10.6 to mate with ActiveTcl, but at least you can avoid patching setup.py. I've also found that the current Tcl/Tk Aqua "de-carbon" 8.5 commit at GitHub seems to work fine with Py-2.6.5rc1, both 32-bit *and* 64-bit (I built universal frameworks, so with one install you can support either 32- or 64-bit Python). 64-bit Python's "make test" will crash when it reaches test_tcl, but if you run the test all alone, it passes, and IDLE works fine. I don't understand what regrtest.py does that affects the test when it's not run in isolation. BTW, with Tcl/Tk de-carbon, I have finally built a 64-bit Python with 64-bit numpy/scipy/matplotlib, with mpl's TkAgg front end working fine for the examples I've tried so far. I'm setting up a Homebrew fork to duplicate these installs; if anyone is interested in it, drop me a line; it would be great to have verification that it works elsewhere. -Tom ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/

Building 32-bit on Snow Leopard with tkinter/IDLE (was: Recommended Tcl/Tk with Py-2.6.x)
by Tom Loredo March 9, 2010

March 9, 2010

Quoting Ronald Oussoren <ronaldoussoren(a)mac.com>: > > If we *deploy* for 10.4 or 10.5 > > while building on Snow Leopard, can we get a 32-bit intel executable > > via a universal ppc/i386 build? > > configure --enable-framework --enable-universalsdk > make > make install > > This builds a framework install that contains ppc and i386 code. Thanks, Ronald. According to the Mac/README file, "--enable-universalsdk" should set a path to an appropriate SDK when used on 10.5 or later. "--enable-universalsdk=/" should find an appropriate default, but Ned alerted me that it isn't guaranteed to work in all combinations (there are so many different option combinations in the configuration that I suspect not all have been tested/verified). He suggested that, to play it safe, the configure command should specify the SDK explicitly (full path to the 10.4, 10.5, or 10.6 SDK), as well as set --with-universal-archs (choices are in the Mac/README) and MACOSX_DEPLOYMENT_TARGET (which unfortunately isn't discussed in the README). Regarding building 32-bit *alone* on Snow Leopard, I've been having luck with this, based on a post in a Python bug tracker issue on readline problems: ./configure --prefix=/usr/local/tmp --enable-framework\ BASECFLAGS="-arch i386" \ CFLAGS="-arch i386" \ LDFLAGS="-arch i386" \ MACOSX_DEPLOYMENT_TARGET=10.6 (of course, set the prefix as you need to). It also works deploying for 10.5. I'm not setting the universalsdk here, since I'm not building a universal binary; I hope I'm right that it's not necessary. In any case, it's passing the expected tests. I'm using Py-2.6.5rc1. I was really asking about how to build, on Snow Leopard, a 32-bit version with a *working* tkinter and IDLE. I finally figured out a way to modify setup.py to do this (building against Apple's Tcl/Tk 8.4). It gives an i386 Python framework that passes the tcl tests, with a working IDLE. I'll post the details shortly in case it's of use to anyone, but it's a kind of ugly hack. I don't know if this is interesting enough that I should post the patch on the Python issue tracker; if so, I'd appreciate a pointer to a relevant thread. -Tom ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/

Voice/Speech recognition
by Dan Ross March 8, 2010

March 8, 2010

I'd like to make an app/game for my kids in which they would see a word, read it and the game would be able to recognize if they've read it correctly. Does anyone have any suggestions for speech/voice recognition? Thanks in advance.

py2app and PyQt4
by Emmanuel Blot March 8, 2010

March 8, 2010

Hi All, I would like to write a setup.py script for py2app, but I keep bumping into an error I don't know how to resolve: How do I specify a dependency on PyQt4 ? * If I do not tell py2app about the dependency, it successfully creates a Mac OS X application package, but fails to run it as it cannot find the PyQt4 libraries * If I specify 'PyQt4' as a dependency in setup.py, py2app fails to resolve this dependency and refuses to build up the package, with the following error from the underlying pkg_resources module: Traceback (most recent call last): File "setup.py", line 54, in <module> setup_requires = ['py2app'], File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/distutils/core.py", line 152, in setup dist.run_commands() File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/distutils/dist.py", line 975, in run_commands self.run_command(cmd) File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/distutils/dist.py", line 994, in run_command cmd_obj.ensure_finalized() File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/distutils/cmd.py", line 117, in ensure_finalized self.finalize_options() File "/Library/Python/2.6/site-packages/py2app/build_app.py", line 295, in finalize_options self.eggs = require(self.distribution.install_requires) File "/Library/Python/2.6/site-packages/distribute-0.6.10-py2.6.egg/pkg_resources.py", line 648, in require needed = self.resolve(parse_requirements(requirements)) File "/Library/Python/2.6/site-packages/distribute-0.6.10-py2.6.egg/pkg_resources.py", line 546, in resolve raise DistributionNotFound(req) pkg_resources.DistributionNotFound: PyQt4 I've added the following dependency requirement in the setup.py file install_requires = [ 'PyQt4' ], When I run python from the command line, I don't have any issues to load PyQt4: Python 2.6.1 (r261:67515, Jul 7 2009, 23:51:51) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import PyQt4 >>> print PyQt4 <module 'PyQt4' from '/usr/local/homebrew/lib/python/PyQt4/__init__.pyc'> >>> Moreover, the application loads and executes fine when it is run from the command line. However, py2app keeps failing to find PyQt4. Any idea about how to solve this issue? I've googled it but had no luck, "pkg_resources.DistributionNotFound: PyQt4" gives no answer. Thanks in advance, Manu If that matters: Snow Leopard 10.6.2 w/ full 64 bits installation on a MBP Unibody
