py2app warning: may need to include email.Util
by Russell E Owen Aug. 6, 2007

Aug. 6, 2007

My py2app-bundled Mac application recently started failing with "no module named email.Util" when trying to display images. It turns out pyfits uses urllib which uses email.Util, which apparently has been renamed email.util with some kind of clever lazy import code so one can still use email.Util. Apparently the cleverness is too much for py2app's module finder. Anyway, the easy workaround is to specify email.Util as a necessary module to import. But I'll report a python bug or submit a urllib patch. -- Russell

XCode fails to see py2app
by Dennis Ng March 20, 2007

March 20, 2007

Dear all, Following the examples http://developer.apple.com/cocoa/pyobjc.html as well as using PyObjC 1.4 installer for (Universal) Python 2.4 on Mac OS X 10.4 I have got an error message that Xcode cannot find py2app. There is a thread on this topic but there is no answer on how to deal with it. So I raised it again. It seems that it is a common problem to newbie and for newly installed environment. It is noted if one run the source manually i.e. follow the instruction using Xcode, interface builder, drop to terminal and do the python setup.py py2app The program will works but if you compile it under Xcode, it cannot: The details is as below and you may note that somehow Xcode can only points to the Java and nothing Python in the compile environment: Building target “Development” of project “PyAverager” with configuration “Development” — (1 error) cd / setenv ACTION setenv APPLE_INTERNAL_DEVELOPER_DIR /AppleInternal/Developer setenv APPLE_INTERNAL_DIR /AppleInternal setenv APPLE_INTERNAL_DOCUMENTATION_DIR /AppleInternal/ Documentation setenv APPLE_INTERNAL_LIBRARY_DIR /AppleInternal/Library setenv APPLE_INTERNAL_TOOLS /AppleInternal/Developer/Tools setenv BUILD_COMPONENTS "headers build" setenv BUILD_DIR "/Users/testuser/Desktop/pyObjC -

My environment is quite common for macbook (Intel) i.e. it has the current version Python in /Library/Frameworks/Python.framework/Versions/2.4/ as well as an older library in /Library/Python/2.3/ but calling python would use the newer library The newly installed PyObjC has this: /Developer/Python/py2app/ /Developer/Python/PyObjC/ The py2app example like TinyTinyEdit run ok under terminal compile method. Somehow the setup script cannot find the two libraries pyobjC installed and seems to use Java environment. Any hint? Best regards. Dennis

Regarding universal python framework....
by Christopher Barker Jan. 31, 2007

Jan. 31, 2007

Hi all, I had a question/comment from a numpy/Scipy developer that I was asked to forward on: > > To get the "definition" of "universal" I went to > > http://en.wikipedia.org/wiki/Universal_Binaries > > > > the last paragraph says: > > Apple's Xcode 2.4 takes the concept of universal binaries even > > further, by allowing four-architecture binaries to be created (32 and > > 64 bit for both Intel and PowerPC), therefore allowing a single > > executable to take full advantage of the CPU capabilities of any Mac > > OS X machine What are folk's thoughts on building "quad binary" universal builds in the future? Is there much point? Are there any 64bit Intel Macs? What difference might a 64bit build make on a G5? For the app in mind, this is the issue: I am interested in 64-bit because it is supposed to be able to open >4GB data files in memmap mode (that is, you could treat any large data set like a normal numpy array and *instantaneously* access sub-data without ever loading the entire file. Note that this works even with small amounts of physical memory, only the (theoretical) memory address space has to be 64bit.) thoughts? -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

/Library/Graphics/Patch .plugin for Quartz Composer
by Chris McClimans Jan. 30, 2007

Jan. 30, 2007

I was poking around the working Quartz Composer Patch Plugin build I made and found the exact version I used to create it in Contents/ Info.plist: <key>py2app</key> <dict> <key>template</key> <string>bundle</string> <key>version</key> <string>0.2.5</string> So I downloaded http://svn.red-bean.com/bob/py2app/releases/ py2app-0.2.5/ and it still didn't work. So I started looking at the imports. The culprit is an upgrade from the included macholib-0.8 from py2app-0.2.5 to macholib-1.0 or higher. If you install a macholib version beyond what is included with py2app-0.2.5, the build process works differently. For me it results in two binaries. (sample setup.py and PyQcPatchLoader.py below) Results after 'python setup.py py2app' with py2app-0.2.5 and the included macholib-0.8: $ls dist/PyQcPatchLoader.plugin/Contents/MacOS/ PyQcPatchLoader Results after 'python setup.py py2app' with py2app-0.3.1 and macholib-1.0 or higher: $ls dist/PyQcPatchLoader.plugin/Contents/MacOS/ PyQcPatchLoader python I suspect a diff of: http://svn.red-bean.com/bob/py2app/releases/py2app-0.2.5/src/ macholib/ #aka macholib-0.8 and http://svn.red-bean.com/bob/macholib/tags/macholib-1.0/macholib/ has the culprit embedded in there somewhere. Any thoughts or suggestions would be greatly appreciated. -chris ps. I'm moving this thread to pythonmac-sig as it's not really pyobjc- dev related and that list seems to get more volume.

Stripping for i386 on G4, bad install of py2app
by Chris Van Bael Jan. 28, 2007

Jan. 28, 2007

Hi all, I want to ask you for some help, for a problem that's coming back to bite me again. See: http://mail.python.org/pipermail/pythonmac-sig/2006-November/018421.html Problem is that striping for i386 doesn't succeed on a G4. Did the uninstall according to the py2app webpage, but still fails. I had this problem on my G4 Mini and I could only resolve it by reinstalling OS X completely. Now I have an iBook G4 with the same problem. Reinstalled OSX completely, but still no success. If first installed setuptools and py2app with the bootstrap method, when a build with that failed, I uninstalled it and re-installed it according to this guide: http://svn.pythonmac.org/py2app/py2app/trunk/doc/index.html#installation I know of some other people that where also not succesfull in installing py2app/setuptools. Is there maybe some problem with the installer? I do it every time according to the guide and yet most of the time it fails... Greets, Chris

Threaded GUI application....
by Tim Ansell Jan. 28, 2007

Jan. 28, 2007

Hello, I currently have a threaded GUI application. I have a "GUI" thread (which is always the main thread), a "Media Download" thread, and a few other misc threads. Everything worked fine on Mac OS X until I added the "Media Download" thread. I was very careful to make sure GUI calls only occured in the GUI thread (because otherwise you get "Bus Error" segfaults). However, after I added the "Media Download" thread, I started getting "Bus Error". I couldn't figure out why for a long time, the "Media Download" thread definitely makes no GUI calls in any of my code. I trace the error to urlib.py in the standard library. The culprit is the following lines, ---- if sys.platform == 'darwin': def getproxies_internetconfig(): """Return a dictionary of scheme -> proxy server URL mappings. By convention the mac uses Internet Config to store proxies. An HTTP proxy, for instance, is stored under the HttpProxy key. """ try: import ic except ImportError: return {} ------- It dies on the "import ic" line with a "Bus Error". I'm assuming this is because the IC module interacts with the GUI, and as it isn't the main thread causes this problem. So, my question is, how do I get around/fix this? Is there a way to "catch" the Bus Error and just throw an exception? Can I override the getproxies_internetconfig function? Are there any other standard library functions I should avoid calling in a non-main thread under Mac? Thanks for your help. Tim Ansell

Opening an app from another app under different OS X versions
by David Woods Jan. 25, 2007

Jan. 25, 2007

My wxPython application has a context sensitive help system, using wx.html.HtmlHelpController(), which also contains a Tutorial for the program. Users like to leave the Help window open while they are simultaneously working in the application. To allow this, I set the Help application up as a free-standing application that I can call from my regular application when it is needed. (This is necessary because of issues with menu construction.) My applications are built using py2app, so the call I've been using looks like this: os.system('open -a TransanaHelp.app') This works on OS X 10.3, and it works when I'm running under Python on OS X 10.4, but I have not been able to get anything along these lines to work under OS X 10.4 once my app has been bundled up with py2app. It's like the Help app tries to launch, but then it immediately, and silently, shuts down. (i.e. the Console doesn't report anything.) os.spawnv() and os.popen2() don't work either. Does anybody have any ideas for how I can launch a bundled wxPython app from within another bundled wxPython app on OS X 10.4? Thanks for your help, David K. Woods, Ph.D. Transana Lead Developer Wisconsin Center for Education Research University of Wisconsin, Madison http://www.transana.org

Question about "setup.py build"
by Daniel Lord Jan. 25, 2007

Jan. 25, 2007

I admit to being a novice at this yet, but I couldn't find anything relevant to this issue on-line: I am trying to build a version of pysqlite that works with sqllite3 : 1. Apple's installed version doesn't work with the latest so I reinstalled 2. sqllite3 won't build shared libs for universal binaries (typical of a lot of linux/UNIX build since the developers never have that problem except on OS X) 3. so I built Intel-only but.... 4. pysqlite keeps trying to build a universal build (CFLAGS="-O -g - isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc"; etc. etc.) with "python setup.py build" 5. But nowhere in the setup.py or setup.cfg is that set. I explicitly unset CFLAGS and LDFLAGS to ensure it wasn't coming from there. So where is it being set? By the Python build? Where? I jsut need a little pointer or two and I'll do the rest. Thanks. Daniel
