[SciPy-user] can't get weave to run

[James Coughlan]

When I try to run a simple weave example:

from scipy import weave
a=1
weave.inline('printf("%d",a);',['a'])

I get this error message:

Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "C:\PYTHON24\lib\site-packages\scipy\weave\inline_tools.py", line 
325, in inline
    results = attempt_function_call(code,local_dict,global_dict)
  File "C:\PYTHON24\lib\site-packages\scipy\weave\inline_tools.py", line 
375, in attempt_function_call
    function_list = function_catalog.get_functions(code,module_dir)
  File "C:\PYTHON24\lib\site-packages\scipy\weave\catalog.py", line 593, 
in get_functions
    function_list = self.get_cataloged_functions(code)
  File "C:\PYTHON24\lib\site-packages\scipy\weave\catalog.py", line 506, 
in get_cataloged_functions
    cat = get_catalog(path,mode)
  File "C:\PYTHON24\lib\site-packages\scipy\weave\catalog.py", line 275, 
in get_catalog
    if (dumb and os.path.exists(catalog_file+'.dat')) \
  File "C:\Python24\lib\ntpath.py", line 256, in exists
    st = os.stat(path)
TypeError: coercing to Unicode: need string or buffer, NoneType found

I am running Python Enthought Edition--Python 2.4.3 for Windows Enhanced 
Python Distribution, which includes SciPy version 0.5.0.2033. (Weave 
used to work on my computer, back when I was using Python 2.3.)

Does anybody have some suggestions?

Thanks,
James

PS When I run weave.test() I get some successes and some error messages:
