[Pyrex] undefined symbol: None

[John J Lee]

What am I doing wrong here?

tidylib[0]$ python2.2
Python 2.2.1 (#1, Sep  7 2002, 14:34:30)
[GCC 2.95.4 20011002 (Debian prerelease)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import _tidylib
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: ./_tidylib.so: undefined symbol: None
>>>


2.3b1 gives me the same result.  I'm using Pyrex 0.7.2.

The relevant bit of _tidylib.c seems to be this:

 /* "/home/john/comp/dev/wwwsearch/tidylib/_tidylib.pyx":126 */
 __pyx_1 = None(__pyx_v_doc); if (PyErr_Occurred()) {__pyx_filename = __pyx_f1; __pyx_lineno = 126; goto __pyx_L1;}
 __pyx_2 = PyInt_AsLong(__pyx_v_optId); if (PyErr_Occurred())
{__pyx_filename = __pyx_f1; __pyx_lineno = 126; goto __pyx_L1;}
  __pyx_3 = PyInt_AsLong(__pyx_v_val); if (PyErr_Occurred())
{__pyx_filename = __pyx_f1; __pyx_lineno = 126; goto __pyx_L1;}
  __pyx_4 = PyInt_FromLong(tidyOptSetBool(__pyx_1,__pyx_2,__pyx_3)); if
(!__pyx_4) {__pyx_filename = __pyx_f1; __pyx_lineno = 126; goto __pyx$
  Py_DECREF(__pyx_v_ok);
  __pyx_v_ok = __pyx_4;
  __pyx_4 = 0;

      cmdclass = {'build_ext': build_ext}
      )

TIA for any help.
