There is a script in usr/local/bin called bdist_mpkg and a module that should have been installed with Py2App also called bdist_mpkg. If you post your output, maybe we can figure out what's wrong with your installation. For me, the bdist_mpkg script looks like this: #!/usr/local/bin/python from bdist_mpkg.scripts.script_bdist_mpkg import main main() Pretty simple. If I start up Python, I can see where the module is installed: Python 2.4.1 (#2, Mar 31 2005, 00:05:10) [GCC 3.3 20030304 (Apple Computer, Inc. build 1666)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import bdist_mpkg >>> bdist_mpkg.__file__ '/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/py2app/bdist_mpkg/__init__.pyc' I suspect that you installed a PY2App that doesn't match the python you are using, so it's installed in the wrong place. I'm really looking forward to when (soon!) we have the Universal 2.4.3 and we can all just work hard to support that ONE version! -Chris -- Christopher Barker, Ph.D. Oceanographer NOAA/OR&R/HAZMAT (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

Questions about various bits of Intel status
by Andrew Barnert March 23, 2006

March 23, 2006

I'm guessing these answers are all out there somewhere, but I can't find them. So I apologize if I'm being stupid, but: First, what's up with ctypes and other things that need libffi? They complain that it hasn't been ported to darwin x86 and punt. The latest information I could find was a blog at bob.pythonmac.org that says it's been ported, but has no link or information. It looks like PyObjC has a port, but it doesn't work. Should I be looking on the PyObjC and/or ctypes lists instead of here? (A quick search didn't turn up any obvious answers, but I didn't look in-depth.) Next, have the python24-fat changes been ported to the 2.5 trunk? If not, should it be relatively easy to do myself, or should I just wait for the gurus to check it in? If it should be doable, at what version and tag was python24-fat forked from the tree (so I can pull the stock equivalent and make diffs to start from)? How exactly are you supposed to properly install a framework build? I assume that if you sudo make installframeworks, you can't install any modules via .pkg files. (At least the docs say not to do this, and it seems the most likely reason.) But if you just make installframeworks, it fails on /usr/local/{bin,lib}. I ended up sudo'ing it and chgrp/chmod -R on the frameworks, but there must be a better way. Maybe change the makefiles to install -m775/664 instead of 755/644, and -gadmin for the framework bits only? But that may not be what you want when building a package/darwinport/etc.? Without digging through the makefile structure, I'm not sure.... Are trunk builds supposed to mostly work on an Intel Mac? By "mostly work" I mean that if something works on a linux box off the trunk, and on it's in the 2.4 official unofficial release candidate universal installer and works on my Intel box, it'll also work on building off the trunk on my Intel Mac. I'm not expecting any better.... But there are a bunch of things that seem to work in trunk/linux and 2.4.2/universal but not trunk/Intel mac: * test_curses is skipped, even though curses appears to work * all tests that require networking are skipped, even though at least some (maybe all) of the relevant modules work * test_re fails * test_{unicode,unicodedata,codecs} fail * test_{aepack,applesingle,macostools} fail I checked one of the tests, and the Unicode stuff does seem to be wrong (u'\u2000'.isspace() returns False on trunk, True on everything else). I haven't checked the rest. No configure settings seem to make a difference (unless I disable the relevant modules or totally break the build). Finally: Is there some known place to look for this kind of info besides this list, pythonmac.org's wiki, the current trunk code, the bug tracker, and random googling? Is there any way to follow threads from this list's archive without stopping and rooting around at each month boundary? Is there a way to search the archives other than googling with site:http://mail.python.org/pipermail/pythonmac-sig? Thanks.

objc methods to pythonese
by Scott Frankel March 23, 2006

March 23, 2006

Apologies in advance for this tangential question. I'm trying to wrap my head around how Objective-C methods are constructed -- and more importantly, how they're converted to Python methods. Doco I've found uses as an example a method with white space between the parts of the method name. Working with Python has made me gun shy with respect to white space ;) Is the white space syntactically significant? i.e.: [rectangle setWidth:width height:height]; ^ If I understand correctly, this would translate in Python to: rectangle = setWidthheight_(width, height) Correct that the 'h' in the "height" part of the method name is not capitalized? How about the following? - (id)tableView:(NSTableView *)tableView objectValueForTableColumn(NSTableColumn *)tableColumn row:(int)row Would this translate like so? def tableViewobjectValueForTableColumnrow_(tableView, tableColumn, row): Thanks in advance! Reminds me of a friend's reverse polish notation calculator ... Scott

Upgrading to Python 2.4 and handling packages (e.g. Numeric, wxPython, etc.)
by Louis Pecora March 23, 2006

March 23, 2006

Info on converting over installed Python packages to non-Apple Python for those who are newbies or are not gurus (includes me): Bob Ippolito was right. When you upgrade to a non-Apple python you have to re-install all the "add-on" packages like Numeric. You also have to set your paths in the Environment.plist in ~/.MacOSX since any .pth files you formerly used in the Apple distribution directories will not be used in the upgrade. You can get new versions of packages to install from Bob Ippolito's site: http://pythonmac.org/packages/. Just be sure to choose the Framework builds for the system you have on your machine (Panther or Tiger). Many thanks to Bob Ippolito for supplying those packages. If anyone upgrades and needs to use the kinds.py package (which gives platform limits and sizes for floats, ints, etc.) see below for more info on how to get this to work in Python 2.4. Reinstalling the kinds package. I assume you already have the package in your Python files directory. You need to reinstall it after you upgrade to Python 2.4. Do this by opening the terminal, cd to the kinds folder and type sudo python setup.py install give the admin password when prompted. That puts the needed files in the right place down in the /Library directory. But you have to set up a path down in that directory so when you run Python it can find the files it needs for kinds (this is in addition to adding the path to the original kinds source directory where you ran the install script above). Create the file kinds.pth with the single line in it, kinds Save and move this to the directory Drive/Library/Framework/Python.framework/Version/2.4/lib/python2.4/site-packages. That should do it. -- Cheers, Lou Pecora Code 6362 Naval Research Lab Washington, DC 20375 USA Ph: +202-767-6002 email: pecora(a)anvil.nrl.navy.mil

Python 2.4.1 cannot find Numeric, wxPython or anything in the 2.3 directories that Python 2.3 can find. import just gives Traceback errors. Python 2.4.1 cannot find my own modules (which my .pth file in ~/Library/2.3 points to). Am I back to messing with the .plist or $PATH or what? I thought I had this all figured out, but it seems whenever I change anything (e.g. install 2.4.1) I am back to square one. Any help appreciated. -- Cheers, Lou Pecora Code 6362 Naval Research Lab Washington, DC 20375 USA Ph: +202-767-6002 email: pecora(a)anvil.nrl.navy.mil

You sure don't need the nightmare of the registry for Apple to make this kind of thing easier. 1) They could just have a standard place for user-installed command line apps to go (/usr/local/bin is a fine choice), and PUT IT IN THE DEFAULT PATH! 2) you mentioned a programmatic API: In fact, I think there is a plist somewhere that sets the default environment variables for all apps, you could add a PATH entry (or add to it) programmaticly easily enough. 3) PATH is only relevant to command line apps: if you've never gone back from using a GUI -- you'll never need to care about this. 4) I've used a GUI for many years: Macintosh, various flavors of Windows, KDE, etc -- I still keep going back to the command line for some things. -Chris -- Christopher Barker, Ph.D. Oceanographer NOAA/OR&R/HAZMAT (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

Re: [Pythonmac-SIG] Matplotlib give bus error (10.3.9)
by Stewart Midwinter March 22, 2006

March 22, 2006

---------- Forwarded message ---------- From: Tom Loredo <loredo(a)astro.cornell.edu> >mpl built and installed fine, but gave a bus error when trying to plot ("import matplotlib" would work fine, but "import pylab" would give the error). Tom, I came across a bus error in an unrelated package, wax (a pythonic wrapper on wxPython). I was eventually able to track it down to a problem with sys.stdout on the Mac. Then I was able to code a workaround so that the problem statement doesn't get executed on OS X. I did that by inserting print statements (print "got to 1" - and so on) throughout the problem module and noting after which 'milepost' the exception occurred. You could try sticking some of those in your module and see what you get. cheers S
