Building mxDateTime for Python 2.0
by Vincent Marchetti Sept. 24, 2001

Sept. 24, 2001

I am trying to re-compile the mxDateTime shared library to let me use DateTime in Python 2.0 -- the shared library provided throws exception on import about using the wrong version. I have never compiled any type of shared library before, so girding my loins and firing up CW 5 I set up a shared library project and: 1. included the mxDateTime.c code 2. included stub libraries PythonCore and MSL ShLibRuntime.Lib Result: -- Link failure, could not find function 'floor' I knew this is a standard C function, so I threw the stub MathLib into the pot and cooked. Got a bunch of warnings about duplicate definitions of math functions (in PythonCore and MathLib). Decided to ignore warnings. Successfully made the shared library, successfully imported DateTime into Python 2.0 (actually 2.0b1). However, the test script for mxDateTime failed an assertion. Basically, a function DateTimeFromTicks, which uses the floor function, fails to give predicted results. My question: Am I including the correct library in my project to get the "right" version of floor? Thanks, Vince Marchetti

Your application needs python preferences resources (a "Popt" and a "GU<sigma> I" resource). The easiest way to get these is dropping your application on EditPythonPrefs. An alternative (often handier because you don't have to do it after every build) is to create a resource file that includes the Popt and GUSI resource and include this in your build. -- 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

The module is available at http://monsoon.harvard.edu/~mhagger/Gnuplot/Gnuplot.html. The latest version includes support for the Mac. Also, the Mac gnuplot distribution contains a simple console written in python. You can obtain the Mac port of gnuplot at http://users.ece.gatech.edu/~schooley/gnuplot.html. It looks like it hasn't been updated in over 2 years. -- Tony Ingraldi A.M.INGRALDI(a)LaRC.NASA.GOV Phone : (757) 864-3039 Fax : (757) 864-7892

love python, but Discouraged with Mac IDLE
by kevin parks Jan. 16, 2001

Jan. 16, 2001

I am very new to python and perhaps am speaking out of turn here, but please note that i love python, the python community and am extreemly grateful that the langauge even runs on a mac, but i have to say, IDLE is really unpleasant on the Mac. As far as i can tell there is no sytax coloring (looked and looked and looked..) and no pretty printing help no formatting tools, even more noteworthy, no line numbers! I thought that i was crazy, well ok, but i downloaded python onto a pc (yucky) and installed it just to see IDLE in action, and it was super sweet. Also i was used to using alpha to hack tcl and that was pretty sweet as well (people claim there is a python mode for that but i fail to see that as well). Can we look forward to basic nice-ities in macIdle or are these always going to be beyond us because of things that the OS forbids? I hate the PC, have no access to UNIX (god help me, my beloved NeXT is far far away) and am stuck on a mac for the time being ($), and in a twisted way occasionally like the mac for my other tasks (audio). I know that it is a lot of work and that many folks work hard to bring us mac python, but i really want to enjoy hacking with python more than i do and i find that IDLE and the interpreter (another topic altogether) is what keeps me from being productive and happy. The language is freaky awesome, the mac can be cool sometimes too, but the thing inbetween: IDLE is the discouraging part. I hope no one is angry at this post. It was meant to be constructive. Like when your wife, whom you love to no end, tries something with her hair that just isn't working.... best, kevin parks seoul, korea cpsoct(a)lycos.com PS. the mac-specific docs are no day at the beach either!

Re: [Pythonmac-SIG] building extensions on OSX
by Jack Jansen Jan. 3, 2001

Jan. 3, 2001

I haven't played with OSX a lot yet, but I have heard the rumour that it is extremely picky about multiple definitions (on most systems, include MacOS9 and most Unixes Im familiar with, this would be a warning at most, and Python and mysql would happily use their local copy of Pickler_setattr). But, on to the problem: it seems you're including cpickle.c in your shared library. Which you don't have to do, because it's already in Python. -- 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

Re: [Pythonmac-SIG] NumPy extensions on the Mac

This is usually a sign that you have two copies of the numpy code, probably the one that is a Python extension and another one that is linked to your extension. Type checking works by comparing the addresses of the typeobject pointer in the PyObject struct, so this hypothesis is easy to check with the codewarrior debugger. I'm not sure about the details under 1.5.2 (it's been a long time) but you have to make sure that your extension is linked against the .slb that contains the numeric module, and that the two are in the same folder during runtime (there's a few other ways to make sure the right one is found, but this is the easiest). -- 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

building extensions on OSX
by Patrick Curtain Dec. 30, 2000

Dec. 30, 2000

Howdy All! Please, forgive me in advance for all the idiotic statements I'm likely to make, but.... I'm running OSX, Python 2.0b1 and trying to build the MySQLdb extension. I've built it, after a lot of fussing, directing the setup.py script to the Python-2.0b1 directory to find libpython and such. Now, though, if I try to import the module, i get the following: dyld: python multiple definitions of symbol _Pickler_setattr python definition of _Pickler_setattr /usr/local/lib/python2.0/site-packages/_mysql.so definition of _Pickler_setattr And python dumps to the shell prompt. I'm sure there's more and more to tell before this can make sense to anyone, but let me start here. Thanks for ANY help at all. :) --p Patrick Curtain, Husband & Father ( i also write software ) 503/781.6199 http://www.swdev.com/

AppleScripting from Python
by Gerry Brush Dec. 29, 2000

Dec. 29, 2000

Hello, I'm writing as a MacPython 2.0 user. I've followed the instructions for using AppleScript from the "Using Open Scripting Extension from Python" document. What I'm trying to do is send a script written in the QuicKeys Scripting Language to QuicKeys via AppleScript and DoScript. Everything works fine execpt sending multiline QuicKeys scripts. The first line is executed and the remaining lines are thrown away. I've tried packaging the lines in a string with Mac EOL characters after each line of the script, but still no luck. I'm not sure if this is specifically a MacPython problem. Any suggestions? Thanks.

Re: Python 2.0 and MultiUser
by Jack Jansen Dec. 28, 2000

Dec. 28, 2000

Bingo! when you run Python as another user you don't have the preference file, apparently each user has a completely distinct set of preferences files. Therefore, each user that wants to use Python must run InstalPython first. Otherwise the default sys.prefix will be set to whereever the first Python applet was run from. I'll add a note to the readme file, and I'll also add some code to be a bit more intelligent about setting the sys.prefix preference (I could for instance skip this if the folder from which we're run does not contain :Lib and :Mac subfolders). -- 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

Re: [Pythonmac-SIG] urllib problem
by Tattoo Mabonzo K. Dec. 28, 2000

Dec. 28, 2000

Yo, I got caught by that one already. But as always, Jack was quick to point to the solution. Please below. I copy-paste his answer. --- cut Hi, that's not broken, it's only strange. There is absolutely no guarantee how much a read() on a socket will return. The correct way to read all data is to do x = urllib.urlopen(....) alldata = '' while 1: next = x.read() if not next: break alldata = alldata + next However, as it often happens on unix that you get all data in one read call, and sometimes on MacOS too, it's easy to think that read should return everything. Note that read() on files does guarantee that it returns all data. --- cut On Wednesday, December 27, 2000, at 12:11 AM, Moroo Jun wrote: > I tried to run follow program, Python 1.5.2c get all text from web site, > but Python 2.0 doesn't. > In Solaris 2.6, the same program can get all text from web site both with > Python 1.5.2 and Python 2.0. > > --- Begin --- > import urllib > > a=urllib.urlopen("http://www.yahoo.co.jp/") > d=a.read() > f=open("yahoo.html","wb") > f.write(d) > f.close() > a.close() > --- End --- > > I tried them on: > Powerbook G3/333 OS 8.6 > PowerMacintosh 9600/233 OS 9.0 > > -- > moroo(a)jp.fujitsu.co.jp > Fujitsu Laboratories LTD. > > _______________________________________________ > Pythonmac-SIG maillist - Pythonmac-SIG(a)python.org > http://www.python.org/mailman/listinfo/pythonmac-sig > >
