It was a supposed bug when I opened the thread, so the subject line was quite good at the moment. Later it became a bit obscure ;-) > Something appears to have changed wrt the path that Python's sys.modules > reports for imported files. >As far as I know, no-one has yet verified > for sure whether it is a Python bug or merely a platform-specific change > that Pythoncard will need to adjust for.

Alex, would you discuss a bit more about this Python issue ? sys.modules reportings about the imported files has changed ? Since when ? Does this affect the Apple installed python or the "third parties" ones ? Thanks!

Using distutils with XCode
by Paul Kinnane Oct. 9, 2005

Oct. 9, 2005

Hi I am trying to port a python library which I have running on the PC to the Mac. Can I compile a python distribution files (compiled C) using the distutils on OSX10.4. I don't have CodeWarrior 7 and wondered if it was possible to manually compile the library using XCode? I see it is possible using MPW (http://www.nevada.edu/~cwebster/Python/MPWHOWTO/MPWHOWTO.html) - however I can't run MPW without OS9. To date, I can compile the library in XCode, although it has trouble linking with the PythonCore library. I've also tried compiling the library on Darwin, and get a "Symbol not found : __cxa_pure_virtual" error when I do the import in python. Paul

py-rdiff-backup?
by Chinook Oct. 8, 2005

Oct. 8, 2005

*** I posted this on the rdiff-backup list, but the traffic there is next to nothing, so it being a python package I'm taking a shot at the pythonmac community :-) *** Ok, lets take a different shot at this :-) I would like to checkout rdiff-backup usage on Mac OS X (10.4.2) 1) Are there any other such users out there? 2) I want to use the full functionality but there are two limitations, namely ACLs and EAs. The various port packages have "librsync" included as a dependency but do not include pylibacl and pyxattr. 2a) EA support: supposedly with "pyxattr" recognized, but in Mac OS X the proper module is "xattr" which I have in my pythonmac 2.4.1 installation (/usr/local/) and in the DarwinPorts environment (/opt/local/). Other than my PATH variable, how do I get rdiff-backup to recognize "xattr?" 2b) ACL support: supposedly with "pylibacl" recognized, but I can't find any such thing for Darwin. The "standard" download setup.py checks for Linux and Free-BSD only and quits. Having looked (with my limited understanding) at the Carbon "FPGetACL" which pylibacl would, I believe, have to get down to, I'm not adventurous enough to just add Darwin to the setup.py. Is there any merit in pursuing this aspect? Thank you, Lee C

Extending Python (OS 10.3.9)
by Kevin J. MacKenzie Oct. 7, 2005

Oct. 7, 2005

Hi everyone, I am attempting to convert some time critical code into C to be imported as a module into python. This is on OS X (10.3.9) using the bundled 2.3.3 version of python. I am working through the extending python tutorial but am having trouble wrapping my head around some things which are a little above my knowledge of C and OS X. Full code is copied below. But, basically what I've done is created 2 source files, mod.c and sum.c with a header file sum.h (as per the tutorial). For compiling, I am doing the following: [code] [xxxxxxx@viridian 14:03:21]$ gcc $PYTHPATH sum.c -o sum.o [/code] Where $PYTHPATH ='-I/System/Library/Frameworks/Python.framework/Versions/2.3/include/python2 .3' So gcc can find python.h sum.c compiles fine. The wrapper file mod.c, however gives me the following. [code] [xxxxxxx@viridian 14:03:12]$ gcc $PYTHPATH mod.c -o mod.o ld: Undefined symbols: _main _PyArg_ParseTuple _Py_BuildValue _Py_InitModule4 _sum [/code] I was under the impression that I should compile the source files, and then compile a shared library by the following: [xxxxxx@viridian 14:03:14]$ gcc $PYTHPATH mod.o sum.o -o mod.so However, the compile is pooching out on the compile of mod.c I am hoping that someone with more experience with this may give me some tips regarding how to go about this. The code from the tutorial I have pasted below. Thanks. kjm // ------------------------------------------------------------ // begin sum.c #include "sum.h" int sum(int a, int b) { return a + b; } int main(int argc, char* argv[]) { return 0; } //---------------------------------------------------------- //----------------------------------------------------------- // being sum.h int sum(int a, int b); int main(int argc, char* argv[]); //----------------------------------------------------------- //----------------------------------------------------------- // being mod.c #undef _DEBUG #include <Python.h> #include "sum.h" static PyObject* mod_sum(PyObject *self, PyObject *args) { int a; int b; int s; if (!PyArg_ParseTuple(args,"ii",&a,&b)) return NULL; s = sum(a,b); return Py_BuildValue("i",s); } static PyMethodDef ModMethods[] = { {"sum", mod_sum, METH_VARARGS, "Description.."}, {NULL,NULL,0,NULL} }; PyMODINIT_FUNC initmod(void) { PyObject *m; m = Py_InitModule("mod",ModMethods); if (m == NULL) return; }

Is it possible to programmatically burn a CD with Python. Or indeed from the shell, as a pinch? -- Cheers, Simon B, simon(a)brunningonline.net, http://www.brunningonline.net/simon/blog/

XCode fails to see py2app
by Frederick C. Lee Sept. 29, 2005

Sept. 29, 2005

Greetings (totally green neophyte trying to crawl back into the MacPython camp): I recently ran install pyobjc 1.3.7. The following is one (1) of the modules installed (copied from installer dialog window): (Required) Pure Python modules and packages Installed to: /Library/Python/2.3/site-packages I did a check to see if I got the stuff installed: [/Users/Ric]ls /Library/Python/2.3/site-packages Extras.pth PyObjC.pth dbflib.py dbflibc.so py2app.pth shapelib.pyc shptree.so PyObjC/ README dbflib.pyc py2app/ shapelib.py shapelibc.so So it appears the installation went okay. I started to build the demo project "PyAverager 2" and got the following build error: /usr/bin/env /Users/Ric/Downloads/PyAverager2/setup.py py2app --alias Traceback (most recent call last): File "/Users/Ric/Downloads/PyAverager2/setup.py", line 38, in ? import py2app ImportError: No module named py2app ======================================== This appears to be a simple XCode 2.1 adjustment (correct?). But which environment variable to I change? Do I need to add a search path to the headers? Or what? I'm lost here. Regards, Ric. The following is the setup.py that was read: #!/usr/bin/env python # # ------------------------------------------------ # # CHANGE ABOVE OR EDIT THE "Shell Script Files" # PHASE TO START THE THIS SCRIPT WITH ANOTHER # PYTHON INTERPRETER. # # ------------------------------------------------ # """ Distutils script for building PyAverager.

space in file path
by Zhi Peng Sept. 29, 2005

Sept. 29, 2005

Hi! Obviously the macfs.FSSpec(file) does not accept form of file name as following: file = "//Applications//Program\ Filename.rsrc" (or //Applications//Program Filename.rsrc") But if I have space between file name as above, what I need to do. Anyone knew? Thanks in advance. Zhi --------------------------------- Yahoo! for Good Click here to donate to the Hurricane Katrina relief effort.

distutils "unsupported operand type"
by Eli Stevens (WG.c) Sept. 28, 2005

Sept. 28, 2005

I'm trying to build Cheetah 0.9.18 (the template engine) on OSX 10.3 with python 2.4.1 (a framework build). I found other people having similar problems with Zope or PIL. I get an error inside the distutils stuff that seems like it's tracing back to how python was built. As best I can tell, it's looking for an OPT var inside of the Makefile (possibly the one at /Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/config/Makefile ?). The closest thing to a solution that I've seen was at: http://nixdoc.net/files/forum/about47446.html But that's just an accurate assesment of what's wrong. Has anyone else encountered this? Am I just searching on the wrong terms? Thanks, Eli Here's the command lines and stack traces: ~/Downloads/Cheetah-0.9.18> python ./setup.py build running build running build_py running build_ext Traceback (most recent call last): File "./setup.py", line 13, in ?
