Weird issues with Python 9.2.x and CarbonLib/Tkinter
by Tom Kacvinsky Feb. 9, 2003

Feb. 9, 2003

Hi all, I am using Adobe's OpenType FDK on my PowerBook G4 running MacOS 9.2.2. I have had some weird crashing issues with the interpreter. I am using the class version of Python 9.2.1 and 9.2.2. Everytime I crash, the MacsBug log I get says there is an umapped memory exception in _tkinter.ppc.slb. IF I disable CarbonLib 1.6, the problems go away. Have you heard of this and do you know of a fix (aside from using the MacOS X version of the FDK). I need the Tkinter stuff for the classic FDK, which the 2.3 alpha does not have, nor does the 2.2.1/2.2.2 Carbon version of Python. And I cannot use PYthon 2.1.x because the shared libs in the FDK are compiled for Python 2.2.x. Thanks and regards, Tom

Togl on OS X 10.2 with apple's X11? CONST84_RETURN errors in tk headers
by Ivan Kozik Feb. 8, 2003

Feb. 8, 2003

Hello, I am trying to compile Togl (a tcl/tk opengl library) on OS X 10.2 because apple's X11 now natively supports opengl. When I run make in the Togl source directory, I get a bunch of CONST84_RETURN errors in the Tk 8.4 distribution: /Library/Frameworks/Tk.framework/Headers//tkDecls.h:237: illegal external declaration,

Is there anything I can do to fix them? Are my headers broken? Thanks, Ivan

python extension namespace clash in jaguar python?
by Bob Ippolito Feb. 7, 2003

Feb. 7, 2003

Using the stock python from OS X 10.2, is there a way around the issue where two python extensions with the same name (but in different packages) will cause a clash? I know this has been resolved in later builds of python, but it would be nice to be able to get around this without distributing a custom build. In my particular example, I was seeing how possible it is to port pygame to the stock python using methods similar to what the pyobjc team has done... pygame has a module called time, which clashes with python's time. If I import pygame.time, and then import time, both of them are actually pygame.time, and vice versa if I do it in reverse order. I know I could rename pygame.time (and change inittime) to something else, but that doesn't seem like a very good solution. Are there any alternatives? -bob

Osxserialports
by Pascal Oberndoerfer Feb. 7, 2003

Feb. 7, 2003

Hello all. To access a list of currently available serial devices on MacOS X you can now try an extension. The extension is at <http://www.urheberrecht.org/institut/workers/oberndoerfer> A short description would be >>>import osxserialports >>>osxserialports.all() # or osxserialports.modems() or osxserialports.rs232() This returns (should return) a list of dictionaries, each dictionary containing some information about a device. The list will be ampty of course if no serial devices were found. There's a test script called osxsp.py as well. I found it useful to solve the problem that you cannot predict what USB port a USB-to-serial adapter will be connected to. Would (interested) people provide feedback on the extension please and maybe what more they'd like to see exposed from IOKit/IORegistry? Cannot promise anything though ;-) Thank you. Pascal

Accessing CoreFoundation/IOKit from inside a module?
by Pascal Oberndoerfer Feb. 6, 2003

Feb. 6, 2003

Hello all. Isn't it possible to use stuff from "#include <CoreFoundation/CoreFoundation.h>" from inside a module? Everything compiles and links fine (using "python setup.py build") as long as I don't use for example "CFDictionarySetValue()". If I use it I get the following linking error message: > cc -Wl,-F. -bundle -framework Python build/temp.darwin-5.5-Power > Macintosh-2.3/osxtestmodule.o -o build/lib.darwin-5.5-Power > Macintosh-2.3/osxtest.so > /usr/bin/ld: build/temp.darwin-5.5-Power Macintosh-2.3/osxtestmodule.o illegal > reference to symbol: _CFDictionarySetValue defined in indirectly referenced > dynamic library > /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation The same happens with IOKit, of course... > /usr/bin/ld: build/temp.darwin-5.5-Power Macintosh-2.3/osxtestmodule.o illegal > reference to symbol: _IOMasterPort defined in indirectly referenced dynamic > library /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit What am I missing here? Is this a known issue? What's the problem with an "indirectly referenced dynamic library"? Thanks for your help! Pascal And yes, I can access the module from the python interpreter, if the linking doesn't fail.

Transparent methods (and more) in Python...
by JR Feb. 5, 2003

Feb. 5, 2003

Python linguists and MacPython geeks, I have a few questions that my books and experience aren't answering... 1) If I override __del__ will Python's (normal) garbage collection et al. *still* go off behind it or (since I'm overriding) am I then responsible for manually triggering it. If the later, how does one do so (I saw something about some "super.blah" notation but haven't digested that just yet)? 2) Is there an elegant method of loading CLI args into sys.args in MacPython (not MachO Python) in OS X without employing Apple Events? 3) Is there a transparent assignment op I can override (i.e., the equivalent of what might call __=__ ... no not __eq__)? If not, is there a brief synopsis that describes why the language (seemingly ... at least from my mental vantage point) cannot support he same? Thanks, JR

environment.plist (was: fixing the PATH environment variable for 2.3)

Did you log out and log back in again after editing environment.plist? That is certainly necessary. After that, I would expect environment variables in environment.plist to show up in Terminal. They certainly do on my system. I define PYTHONPATH, PYTHONSTARTUP and PYTHONDOCS in environment.plist and nowhere else and they show up fine in Terminal (they are listed by the "env" command and they are seen by the command-line version of Python). If this is not the case for others, I'd certainly like to know about it (especially if anybody has an explanation). I wrote the html page in question and would like to correct any false information. But I'm having trouble imagining why it would work fine for me and not others. -- Russell

Detecting serial devices
by Pascal Oberndoerfer Feb. 3, 2003

Feb. 3, 2003

Hello all. It's (again) about detecting currently available serial devices (like modems, IrDA, RS232) on MacOS X. Dan Grassi at dan(a)grassi.org: > The answer is to use the IORegistry to find a device. Search for > IOSerialBSDClient with a key of IOSerialBSCClientTyle with a value of > IORS232SerialSteeam. Then get the value of the IODialinDevice or > IOCalloutDevice which are respectively (on my system) > /dev/tty.USA191P1.1 and dev/cu.USA191P1.1. Play with > IORegistryExplorer to get a feel for it. :-) This made me indeed curious. So I finally had a small utility that prints a list of available devices including a device's name, basename, suffix, Callout device file, and Dialin device file. The source is 'SerialPorts.sit' at: <http://www.urheberrecht.org/institut/workers/oberndoerfer/> [It's derived from some Apple sample code. I know it's a mess, but I have never done any C or Objective-C before. So feel free to flame me about programming style etc. ;-) Dan: if you would like to improve this, please do so! Thanks!] If you run it from outside ProjectBuilder you must open Console (/Applications/Utilities) first. My problem is: how can I wrap this snippet so it is accessible from Mac(ho)Python 2.3? Or is there any interest in making the complete IORegistry API available in a systematical way (via bgen, as Jack suggested off list)? Or maybe other parts of IOKit as well? Any help very much appreciated, Pascal MacOS X 10.1.5, Mac(ho)Python 2.3a1, framework install
