[SciPy-user] weave inline install problem

[Hartley, Ed]

Hi
I'm new to SciPY but not to Python and my question relates speciaifcally to
weave.

I've installed SciPy from CVS under linux 
I've built it with gcc 2.96 using a local 2.95 for the special function
libraries.

The SciPY tests passed the weave compile tests failed but ran by defaulting to
using python.
I'm now working through the weave tutorials and I've hit a problem which I'm
assuming is installation related in some way. 

This works

	>>> import weave    
	>>> a  = 1
	>>> weave.inline('printf("%d\\n",a);',['a'])
	1

So I am assuming that the compiler call is OK however this fails

	>>> from weave import inline
	 >>> a = 'string'
	 >>> code = """
	 ...        int l = len(a);
	 ...        return_val = Py::new_reference_to(Py::Int(l));
	 ...        """
	 >>> inline(code,['a'])

In the transcript shown below there's an indication from the line containing
parse error before `::'
that the Py:: construct is not processed correctly so I'm assuming that the 
problem is installation related in some way 
any suggestions on how to resolve this would be  gratefully received.
Thanks
Ed Hartley
