py2app + pyqt: Differences between command-line and double-click
by Berg, Stuart Aug. 15, 2013

Aug. 15, 2013

Hi, I'm using py2app to packages my (cross-platform) PyQt app into a Mac OS X application bundle. (py2app is great, btw!) I was wondering if anyone could point me to some documentation that explains in detail how a python app bundle's launch process differs from launching the python app directly from the command-line. My app bundle seems to function exactly the same in most respects, but my main window doesn't activate unless I manually activate the application via command-tab. I give a few more details in this question on stack overflow: http://stackoverflow.com/questions/16574315/qt-mainwindow-does-not-appear-u… Any ideas, suggestions, or links would be appreciated. Thanks, Stuart

possible interaction between python
by Boyd Collier June 25, 2013

June 25, 2013

Hello All, In late February, I thought I'd give python a try, so I took steps to run it on my Mac. Unfortunately, I didn't keep a good record of what those steps were, but the installation seemed to be successful, in that I was able to run a few simple python programs. However, I now suspect that installing python may have messed up something needed to work with my objective-c programs with Xcode. The symptom of a problem in Xcode is that when I set an Xcode project to use LLDB as the debugger (this is the default debugger), Xcode immediately crashes when the run button in the project window is hit. However, projects run properly when I change the debugger to be used to GDB. At least initially, there was no indication that this problem had anything to do with python. I filed an Xcode bug report with Apple and have been following the steps suggested by Apple engineers to try to track down the problem. This morning, they asked me to run the command /Applications/Xcode.app/Contents/Developer/usr/bin/lldb /bin/ls from the terminal, which I did. Here is the result: > Macintosh:~ bcollier$ /Applications/Xcode.app/Contents/Developer/usr/bin/lldb /bin/ls > dyld: Library not loaded: /System/Library/Frameworks/Python.framework/Versions/2.7/Python > Referenced from: /Applications/Xcode.app/Contents/Developer/usr/bin/../../../SharedFrameworks/LLDB.framework/LLDB > Reason: image not found > Trace/BPT trap: 5 My (perhaps erroneous) recollection is that I installed python 3.3, and I see that what is not being loaded is 2.7. I've sent this result to Apple, but perhaps those of you who have been working with python on the Mac and using Xcode might have experienced a similar problem and might be able to suggest what is going on. I'm running OSX 10.7.5 and Xcode 4.6 (but first had the problem with Xcode 4.2). Thanks very much, Boyd Collier Prof. of Biology, Emeritus San Diego State University

Re: [Pythonmac-SIG] app won't quit?
by Charles Hartman May 28, 2013

May 28, 2013

When I updated my app, I switched from the deprecated wx.PySimpleApp, which had the right default behavior on Mac, to wx.App, which apparently doesn't. (The docs say "You should normally exit the main loop (and the application) by deleting the top window." What's "normal" for a Windows user would baffle my Mac users, and vice versa—but never mind.) I see I can call wxGetApp().ExitMainLoop. But in response to what? What is the event sent by the Mac keyboard or menu Quit command? Binding to wx.EVT_CLOSE doesn't seem to do anything.

Advice wanted on dependency building...
by Chris Barker - NOAA Federal May 28, 2013

May 28, 2013

Hey folks, I'm looking for advice, and maybe even some consensus among the MacPython community, on how to build and distribute packages with non-python dependencies. As we all know, a number of Python packages require libs that are used outside of python itself. These libs fall into (sort of) what I would call two catagories; 1) general purpose libs used by multiple python packages: libpng, freetype, etc. (I'm still confused on why Apple doesn't provide all these -- particularly libpng -- what's up with that?) 2) More specific libs, likely only used by a single python package -- netcdf, proj.4, etc. Users also fall into two categories: 1) Folks that do Python development on OS-X much like Linux, etc -- these folks are likely to use macports or homebrew, or are used to the .configure, make, make install dance. We don't need to do anything to support these folks -- "pip install" generally works for them. 2) folks that want to use a Mac like a Mac, and people that develop for those folks -- these people need binary installers, and may want to be able to use and deploy either packages or applications (Py2app) that will run on systems older than the one developed on, or want universal builds, or ??? - These are the folks I'd like to support, but I'm still unsure as to how best to do that. Way back when Bob Ippolito maintained a repository of binary packages for the mac -- it was a great resource, but he's long since moved on to other things. We kind of get away with it because a number of major package maintainers have done a good job of providing binaries themselves (wxPython, numpy/scipy/matplotlib), but others fail to do so (PIL). Plus some of us have minor packages that we want to distribute. I'd like to put together an archive, much like Bob's was, or like Christoph Gohlke's one for Windows (By the way -- that one is HUGE -- I have no idea how he keeps it up! http://www.lfd.uci.edu/~gohlke/pythonlibs/) But with or without that archive, I still need to build the darn things. So now on to the question: How should the dependencies be distributed? 1) They should be built to match the Python binary being targeted (honestly, I think that's now only the Intel 32-64 bit ones -- PPC machines, and pre 10.6, are getting really rare...) 2) Static or dynamic? IIUC, most successful binary packages for the Mac have relied on statically linking the dependencies -- this works, and is pretty robust. However, it can be kind of a pain to do (though I've finally figure how to do it more reliably!). Also, it seems like a waste to me for packages that use common dependencies -- how many copies of libpng do I really want linked into my single instance of Python at run time? But if dynamic, where do you put them? We'll still want to ship them with the binary, so people have a one-click install. I don't think we want to install them into a standard location, like /usr/local, as that could stomp on something else the user is doing. So: - Do we put the in the Python Framework, say in: /Library/Frameworks/Python.framework/Versions/2.7/lib - This make some sense, but then you couldn't share them between, say, python 2.7 and 3.3 (and however many other versions... - Do we create a new Framework, say: /Library/Frameworks/PythonDeps.framework and put them all there? But this may confuse things for different deployment targets. If we go one of these routes, would we have a separate installer for the libs, and all the other installers would depend on that? Or would each installer put a copy of the libs it needed into the common location, maybe writing over one that's already there (which should be OK -- it should be compatible, or have a different version number, etc.) Note that I've used the term "we" here ;-) I'm hoping that others will join me in following a convention and getting stuff out there, but even if not, I'd love feedback on how best to do it. By the way, the other goal is to build scripts that do the builds the way we need for various libs, packages, etc, so that it's easy to do it all when new builds are required... (maybe use gattai? -- http://sourceforge.net/projects/gattai/) Feedback please!! -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

app won't quit?
by Charles Hartman May 28, 2013

May 28, 2013

I'm coming back to all of this after years away, so I'm sure I'm missing something simple. I've brought an old app into the current world: Python 2.7.5 OS 10.8.3 wxPython 2.9.4.0 py2app 0.7.3 and I rebuilt my setup.py to current specifications. The resulting app works fine (though it's enormous!), but it won't respond to a Quit command (keyboard or menu). The menu-bar header (with my app's name) flashes, but nothing else happens.

Who knows how much time I'll find for this, but my goal is to set up a system (probably a gitHub project), and then others will be able to contribute build scripts for particular packages. I'll certainly annouce that effort when there is something to see... If I can get this in place, I'm hoping that it will, in fact, be easier to build new package by using this system that doing it from scratch by hand, and once you've done it, why not contribute it back? -Chris > Enthought's offerings, for example.

Static Linking...
by Chris Barker - NOAA Federal May 24, 2013

May 24, 2013

As a side note to the main thread about dependencies: How can I static link? I"ve struggled for literally years to get gcc to statically link, but it tries really hard to dynamically link instead. I have written way too many scripts that move or re-name dynamic libs temporarily while building, then put them back after. Then a colleague of mine showed me the really neat trick -- pass the paths to the libs themselves through to gcc with "extra_objects" keyword in the Extension object, like so: extra_objects = ["libhdf5.a", "libhdf5_hl.a", "libnetcdf.a"] extensions = [Extension("netCDF4", sources, libraries=libs, include_dirs=inc_dirs, extra_objects=extra_objects, )] very nifty -- works like a charm. However, when I do this, I had to re-write part of the setup.py -- actually, making it far more simple -- in this case, there was a lot of machinations finding the libs... But Ideally, I"d ;like to build a semi-arbitrary extension with static linking while using the existing setup.py. Is there a way to minkey-path the setup, so I can use the existing one, but re-shuffle it some in place before the actual build occurs? -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

Py2app-built app giving error 255 on loading AppKit?

OS X IDLE and Tkinter users: new releases of Tcl/Tk & Python
by Ned Deily May 19, 2013

May 19, 2013

As I hope you've read already, new releases of Python are now available: 3.3.2, 3.2.5, and 2.7.5. There is also a recent release of Tcl/Tk 8.5: 8.5.14. If you use Tkinter apps, like IDLE, from one of the python.org 64-bit/32-bit OS X installers for 3.3.x, 3.2.x, or 2.7.x for OS X 10.6, 10.7, or 10.8, it would be great if you could install and try out these latest combinations. Tkinter apps have proven to turn up edge cases in the newer Cocoa implementation of Tk 8.5 on OS X; a number of problems have been fixed in recent releases. Since these kinds of problems are difficult to test for automatically, it is important to get real user experience and feedback. Please report any suspected new problems to the Python bug tracker. Thanks for your help! http://www.python.org/download/ http://www.python.org/download/mac/tcltk/ http://www.activestate.com/activetcl/downloads http://bugs.python.org -- Ned Deily, nad(a)acm.org

ASL library
by Ronald Oussoren May 15, 2013

May 15, 2013

Hi, With OSX 10.8 the stdout and stderr streams of applications no longer end up in Console.app, which is fairly annoying when debugging problems in applications created with py2app. I've been researching how I can work around this, and seem to be successfull (the fix is in the repository, and I hope to push out a release next weekend after rebuilding the stub executables in a VM that has a compiler that can generate PPC binaries). Anyways, while researching the solution I started playing with ASL (the Apple replacement for the venerable syslog API), and now know way too much about that libary. I've created a python binding for ASL while the information is still fresh, it for now is only available on bitbucket: <https://bitbucket.org/ronaldoussoren/asl>. I need to do some testing on older OSX releases before I push a proper release to PyPI, even if I don't expect problems. The library not only makes it possible to write arbitrary messages to the ASL database, but can also be used to query the database. Hopefully I won't have to write C code the next time I want to play with ASL :-) Ronald
