Problem with module linking
by Nicholas Riley Dec. 12, 2002

Dec. 12, 2002

Hi, I'm trying to get the Python bindings for Subversion (subversion.tigris.org) to work with Python 2.2.2 on OS X. I've successfully built the bindings with SWIG 1.3.17, but I have a problem importing the modules. % ls *.so _client.so* _delta.so* _fs.so* _ra.so* _repos.so* _util.so* _wc.so* % file _fs.so _ra.so _fs.so: Mach-O bundle ppc _ra.so: Mach-O bundle ppc % otool -L _fs.so _ra.so _fs.so: Python.framework/Versions/2.2/Python (compatibility version 2.2.0, current version 2.2.0) /usr/local/encap/subversion/lib/libsvn_fs-1.0.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 62.0.0) _ra.so: Python.framework/Versions/2.2/Python (compatibility version 2.2.0, current version 2.2.0) /usr/local/encap/subversion/lib/libsvn_ra-1.0.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 62.0.0) % python Python 2.2.2 (#14, Nov 30 2002, 15:47:39) [GCC 3.1 20020420 (prerelease)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import _fs >>> import _ra Traceback (most recent call last): File "<stdin>", line 1, in ?

My guess is it's something related to the linker, but I don't know anything about how Python loads modules.

Framework Python?
by Mel Bohince Dec. 11, 2002

Dec. 11, 2002

Can someone offer an explanation or link to what is meant by a framework versus whatever is the opposite? I keep seeing it tossed around here and there and from the context relate it only to OS X. Is it something different than MacPython or the unix Python in the /usr/bin? Thanks. -: -: -: -: -: -: -: -: \|/ -: -: -: -: -: -: -: -: cU Mel Bohince Pjt Mgr, Arkay Packaging Corporation melbohince(a)att.net http://home.att.net/~melbohince/

Install MySQLdb module on mac os x
by Dieter Gyselinck Dec. 9, 2002

Dec. 9, 2002

Hi, I'm trying to install the python MySQLdb module on os x 10.2 but when I try to run 'setup.py build' I get this error message : ld: can't locate file for: -lmysqlclient error: command 'gcc' failed with exit status 1 I have installed binary mysql-3.23.52 package and it seems to be working fine, I can access my db via php. I am trying to run the MySQL-python-0.9.2 setup. I have changed 'thread_safe_library' to 'NO' but that does not solve the problem. Anyone can help me out with this problem???

How long until OS X Python is ready for prime time?
by David Eppstein Dec. 8, 2002

Dec. 8, 2002

Whenever I look through the archives of this list, or elsewhere on the net, I see: a big mess of multiple versions of Python, in varying states of development, OS-X friendliness and installability, with multiple different UI systems. OS X.2 itself has a python pre-installed (yay!), but unfortunately without UI components. My specific situation is as a developer of a large genealogy program (in C++, for Classic MacOS) that I would like to make native for OS X. This requires a massive rewriting of code and it's beginning to look like it might be easier to start over from scratch in a friendlier programming language. In order to do this in Python, I would need: - OS X native look and feel - Easy download and installation by computer-challenged senior citizens (e.g. standalone app with gzipped download size < 2Mb, no installation of other packages or complicated command lines) - Transparent input and display of accented characters - Multiple windows mixing multi-font text and vector graphics, with ability to capture mouse click location within window It would also be helpful, but not essential, to have cross-platform portability, display or editing of basic HTML text formatting, ability to convert contents of vector graphic windows to bitmap image files, and ability to distribute the program as closed source. Is anything like this available now? If so, which version of Python should I be looking at, and where are the easy installation instructions? If not, will it be available any time soon, or should I be looking around for non-Python alternative solutions? -- David Eppstein UC Irvine Dept. of Information & Computer Science eppstein(a)ics.uci.edu http://www.ics.uci.edu/~eppstein/

Warning: incompatible change in 2.3a0
by Jack Jansen Dec. 8, 2002

Dec. 8, 2002

Folks, I'm about to check in an incompatible change in the CVS trunk for users of Carbon.Qd: no longer will direct access to attributes of grafports be allowed, only the accessor functions will work. Also, the Carbon.Qd.qd object, the Quickdraw global variables, will disappear and you will have to use the accessor functions here also. To give an example, in stead of "port.bounds" you'll have to use "port.GetPortBounds()", and in stead of "Carbon.Qd.qd.arrow" you'll have to use "Carbon.Qd.GetQDGlobalsArrow()". If this causes major inconvenience: clamor loudly and I'll try to create a workaround. But I would rather not: the accessor functions have been required for C programmers since Carbon, and using them will make Python code more readable with the Apple documentation in hand. And, Just, don't worry: I've converted the IDE and the Lib directory to use accessor functions already, I'll check that in before I check in the incompatible change. -- - Jack Jansen <Jack.Jansen(a)oratrix.com> http://www.cwi.nl/~jack - - If I can't dance I don't want to be part of your revolution -- Emma Goldman -

Running Python scripts without full paths
by Paul Berkowitz Dec. 8, 2002

Dec. 8, 2002

Hello. I'm brand new to Python, in OS 10.2.2, but an experienced AppleScripter. (I'm quite amazed by the similarities of the syntax of the two languages, which is making it easy to learn Python. I predict there will be a lot of new converts.) I hope you don't mind a newbie setup question. I'm brand new to Unix as well, and that's probably where I'm going wrong. I was directed to pythonmac-sig when I was trying to find out how to import a module with the Interactive interpreter. I saw a reference to Russell Owen's webpage in the archives, where I found the solution to the problem (which is Mac OS X-only): making my own 'environment.plist' XML file in ~/.MacOSX. The website URL is http://www.astro.washington.edu/owen/AquaEnvVar.html This should be added to the Python FAQ. Now I'm stumped again. Russell's solution works for importing modules from directories that I've added to PYTHONPATH. But I can't get the shell to run script files without the file's full path or having to cd to the file's directory first, even though I've now added the directory to the path shell variable, which in turn has automatically added it to the PATH environment. I can import the script as a module with only the module name in the Interactive interpreter: >>> import module1 Hello module world! This (very simple) script does run when I give its full or relative path name or cd to its directory first, in the shell: [250-166:~] berkowit% python Library/Scripts/Python/module1.py Hello module world! But it won't work like this: [250-166:~] berkowit% python module1.py python: can't open file 'module1.py' The shell does know about its directory now (I set path to include it): [250-166:~] berkowit% printenv PATH /Users/berkowit/bin/powerpc-apple-darwin:/Users/berkowit/bin:/usr/local/bin: /usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/Users/berkowit/Library/Script s/Python:. That next-to-last directory: /Users/berkowit/Library/Scripts/Python is the one with module1.py. Why doesn't the shell find it? Or why doesn't Python find it since it too knows where it is now, as the module import makes clear? Is this another Mac-only problem? Maybe I need to add another key to the environment.plist file? Or am I just doing something wrong? Many thanks for any guidance. -- Paul Berkowitz

ZODB with Jaguar
by Lee Phillips Dec. 7, 2002

Dec. 7, 2002

I want to use the standalone ZODB (Zope Object DataBase) with Jaguar (MacOS X 10.2, included python 2.2). It compiles with numerous warnings and the test.py crashes with a bus error. I've heard that it might work with some older pythons, but I'd rather not downgrade. Has anyone here gotten the ZODB to work with MacOS 10.2.x? Any other suggestions for good object storage, besides just using pickle?

Creating MacBinary files from python
by Chip Brown Dec. 6, 2002

Dec. 6, 2002

I need a way to create Stuffit compatible zip files from within python. My experimentation indicates that a Stuffit created zip file is a collection of MacBinary files, zipped up. I should therefore be able to create a Stuffit compatible zip file from within python (which has built in zip support) as long as I can get the MacBinary versions of the included files. Does anyone out there knows of a python module (that actually works) which can create and disassemble MacBinary files, I would LOVE to know about it. There are such things for PERL and TCL, but I have not been able to find a python version... At worst, is there a darwin command line executable to do this?Thanks!
