Category: Extension Modules Group: None Status: Open Resolution: None Priority: 5 Submitted By: Bill Studenmund (wrstuden) Assigned to: Nobody/Anonymous (nobody) Summary: Example in section 5.3 "Pure Embedding" doesn't work. Initial Comment: I want to use Python to script an existing application. So I was trying the code on http://docs.python.org/ext/pure-embedding.html and found it didn't work. I am using pkgsrc on NetBSD. I have run into two issues. First, PyDict_GetAttrString() does not exist. I have found this to be true for both Python 2.2 and 2.4, the two versions I currently have installed. I made the simple change to use PyObject_GetAttrString(), which looks right. Second, python can't find the module. I named the file multiply.py, and it wouldn't load. It turns out that I had to set PYTHONPATH in my envirnment to make it work. Setting it to '' (empty string) worked. The odd thing about the path issue is that if I ran the python interpreter, it was able to find the module w/o my changing the environment. ---------------------------------------------------------------------- >Comment By: Bill Studenmund (wrstuden) Date: 2006-01-06 14:48 Message: Logged In: YES user_id=148388 Great to hear about PyDict_GetAttrString(). I assume that PyObject_GetAttrString() was the correct change? It turns out the second issue deals with path processing in the embedded code being somehow different from processing in the interpreter. I think the interpreter sets something up that isn't present for the embedded example. I will really appreciate it if we could figure out what's different and add it to the docs. The pictured behavior for "call" is exactly what I want, but not what I get. To be more specific, I had my code print Py_GetPath(), and I compared that with sys.path from the interpreter. C code looking for foo.py (which is in '.'): > ./obj.i386/test foo Path is '/usr/pkg/lib/python24.zip:/usr/pkg/lib/python2.4/:/usr/pkg/lib/python2.4/plat-netbsd3:/usr/pkg/lib/python2.4/lib-tk:/usr/pkg/lib/python2.4/lib-dynload' ImportError: No module named foo utest: loading module foo: No such file or directory In the python interpreter: > python2.4 Python 2.4.1 (#1, Dec 28 2005, 15:58:29) [GCC 3.3.3 (Wasabi NetBSD nb3 20040520)] on netbsd3 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> print sys.path ['', '/usr/pkg/lib/python24.zip', '/usr/pkg/lib/python2.4', '/usr/pkg/lib/python2.4/plat-netbsd3', '/usr/pkg/lib/python2.4/lib-tk', '/usr/pkg/lib/python2.4/lib-dynload', '/usr/pkg/lib/python2.4/site-packages'] The key difference is the '' at the front of the path in the interpreter. Any thoughts? Is there a different list or FAQ I should look at? ---------------------------------------------------------------------- Comment By: Reinhold Birkenfeld (birkenfeld) Date: 2006-01-06 11:33 Message: Logged In: YES user_id=1188172 The PyDict_GetAttrString issue is corrected in the current devel docs. No clue about the other. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1398781&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
