Re: [Pythonmac-SIG] MacPython 2.0c1 and LinearAlgebra/Matrix

Recently, Paul Miller <paulm(a)avacadcam.com> said: > I am having problems using Numeric with Python 2.0c1: > > import LinearAlgebra > > and > > import Matrix > > both report that the modules are missing. Both of these worked with 2.0b1. > > Is this a bug, or have I just missed something? No, this is a bug. And a difficult one to fix:-( Let me explain, maybe someone has a simple solution. The Numerical people have gone over to distutils completely, but unfortunately distutils doesn't work on the Mac yet. Actually it could work, because some of us have put quite some effort into it over the last couple of weeks, but the distutils crowd chose to exclude the Mac stuff for the 2.0 release. This is sort-of understandable, and I might even grudglingly agree with them (grudgingly, because I spent hours to get things working just vefore I left on holidays only to find that nothing had happened with the code when I returned two weeks later:-( ), but it leaves the Numeric/MacPython combo is a sad state. The old method of simply adding Numeric:Lib to sys.path doesn't work anymore, and the new distutils method doesn't work yet. I could manually revert my sourcetree to the old state before the distribution, but maybe someone has a better idea? -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm

stackless/uthreads/continuation
by Craig Amundsen Oct. 20, 2000

Oct. 20, 2000

Hello - I've been wanting to mess around with microthreads for a while now, so when Just made a Mac version of Stackless available (Thanks!) I went and grabbed it and uthread.py. I'm having a spot of trouble getting into the microtheads, though. One of the first lines of code in uthread.py is 'import continuation'. I've searched around a bit and can't locate anything called continuation on my machine, or any promising files on the net to use either. Does anyone have any suggestions how I might continue? TIA, - Craig

Building Python 2.0 modules on OSX PB (MySQLdb)
by Andrew Zeldis Oct. 19, 2000

Oct. 19, 2000

Well much to my shock Python 2.0 built beautifully, with (I think) shared libraries using --with-dyld. However I'm having some problems making the MySQLdb module. I know next to nothing about development on Unix, but by messing with options in the setup script I was able to get the module to build. The version for 2.0 is build using a new setup.py script: > python setup.py build I believe it gets to the linking phase, where the command: cc -bundle -undefined suppress build/temp.darwin-1.2-Power Macintosh-2.0/_mysqlmodule.o -R/usr/local/lib/mysql -lmysqlclient -lz -o build/lib.darwin-1.2-Power Macintosh-2.0/_mysqlmodule.so fails: cc: unrecognized option `-R/usr/local/lib/mysql' I guessed that -R is the runtime_library_dir, so I tried commenting out "runtime_library_dirs" uncommenting "library dirs" in the build script; it built and installed but failed on use: dyld: python multiple definitions of symbol _strtol /System/Library/Frameworks/System.framework/Versions/B/System(strtol.o) definition of _strtol /usr/local/lib/python2.0/site-packages/_mysqlmodule.so definition of _strtol No doubt this would be easily solved by someone who understood the intricacies of OSX's linker and loader...

Quit the IDE and the interpreter if they are running. Check that you actually installed it, the default is not to install it. Re install with the "custom" option. Do'h! Trash the preferences in the folder "python" in your system folder's preferences folder. Use the EditPythonPrefs has the line... $(PYTHON):Lib:lib-tk....what's worth pointing out here is that although the field looks like it's clickable, it's actually a field where you type.... bad bad interface!!....especially since you have to use the arrow keys to move around....oh, and don't think about clicking any of those buttons unless you want to crash :-) Run ConfigurePython. I think this sets the PYTHONPATH thingy. run the IDE, type "import sys" and then "sys.path" to see if the path to the Tk stuff is there. ...at the interactive prompt, type "import Tkinter" and see if it errors. If it is, drop any tk example files on the interpreter, don't try to run em through the IDE. give the interpreter more memory ( I think it needs loads 20MB?!) As a last and desperate resort I try trashing any .pyc files I can find then running through it all again....after a bit of mucking about I got it going... hope this helps tom

Re: [Pythonmac-SIG] 2.0c1 stdio window options

It means "if the last operation to the window was a write, not a read". If this is the case there's a good chance the user hasn't had a chance to look at it, so we don't want to close the console window.

Tkinter on Mac OS9
by Edward Irvine Oct. 18, 2000

Oct. 18, 2000

Hi all, I'm looking for some hints as to how to get Tkinter on Macs to work. I've downloaded and installed python 1.52, and tcl/tk 8.3 (from www.scriptics.org). But what now? Idle can't find _tkinter (which is presumably called by Tkinter.py, which Idle *can* find*. I'm brand new to this list, so sorry if this is a FAQ (but I've looked there). I teach computing at a large high school and a number of my more gifted students are pretty keen on Python. They can get Tkinter and Pmw working on their PCs at home, but it is pretty important that they can get it to work on our school iMacs. _____________________________________________________________________________ http://clubs.yahoo.com.au - Yahoo!

help for a MacPython begginer
by Jhst463＠aol.com Oct. 18, 2000

Oct. 18, 2000

I've recently taken up Python scripting, and've read "Python Tutorial" by Guido himself but still I've no idea about what to do in Python other than write Fibonacci functions. I'm very well acquainted AppleScript and hope learning Python can act as a bridge between AppleScript(high-level langs) & C/C++/Obj-C(low-level langs). Here's my laundry list of questions: What is the difference between the "Modules" & "Lib" folders? Are modules required to reside in the *modules* folder? Is it safe to make full use of the Mac's superior file system inside Python?(scripts & modules w/ 31 chars?, 8-Bit characters(both for file names & inside the code itself?)) May aliases(of scripts, modules, shared libraries) be used? Is there a limit on how deep files can be nested? What is the purpose of the following directories from version 2.0? Lib Tools Extensions Include Mac Modules Scripts Is there any Mac-specific tutorials available, preferably in PS, PDF or HTML? Thanks in Advance Jonathan H. Mast Jhst463(a)aol.com

2.0c1 stdio window options
by David Goodger Oct. 18, 2000

Oct. 18, 2000

The new EditPythonPrefs gives the following options: Keep stdio window open on: o Always o Unseen output o Error exit o Never Perhaps I'm dense, but I don't understand what "Unseen output" means. Can anyone explain, and perhaps come up with a better phrase? It's a small nit, but I would change the option to: Keep stdio window open: o Always o On unseen output (or something better ;) o On error exit o Never It scans better. Looking forward to 2.0final! -- David Goodger dgoodger(a)bigfoot.com Open-source projects: - The Go Tools Project: http://gotools.sourceforge.net (more to come!)

State of BBPy? More general Tkinter development question.
by Russell E Owen Oct. 17, 2000

Oct. 17, 2000

I have gotten BBPy to work with Pyton 1.6a2 (but not 1.5.2) by changing "from Types.py import *" to "from types.py import *" (i.e. types must be lower case) in PythonSlave.py. One simple script I tried ran fine. However, when I tried to run a Tkinter script I'm working on Python hung and so did BBEdit. (In general BBEdit seems susceptible to hanging if Python hangs when using BBPy). Is this a known limitation in BBPy, that it fails with Tkinter scripts? Or did I just get unlucky and have something fail, or what? Any suggestions for a good environment in which to build Tkinter applications would be very much appreciated. It doesn't have to be on the Mac. The present business of editing the file, dropping it onto PythonInterpreter, having it choke, analyzing the output and doing it all over again is pretty painful. Also, any suggestions on ways to interact with a Tkinter script while building it would be appreciated. I'd like to start things up and then be able to talk to my widgets and generally exercise my code interactively. Regards, -- Russell

Re: [Pythonmac-SIG] Process-to-Process Communication Toolbox support in Python.

PPC toolbox is indeed unsupported in Python. It also probably isn't worth investing time in it, as it will disappear with MacOSX. -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm
