I compiled it just fine on a Debian woody machine.  One difference is that
I used python 2.2.2, not python 2.3.  I suspect the 2.3 version of python
is what's causing your problem.  Go back and install 2.2.2 (or
something similar to that) and you should be fine.

I'm using the same one.

Yes, that's been reported before, and I think there's an #ifdef somewhere
in the visual sources.  [poking around...]  

If, for some reason, you don't want to take my advice above and use
python-2.2.2, then you can try getting around this particular problem
by changing the line in cvisual/CXX/Include/CXX_Config.h that says

	#define STANDARD_LIBRARY_HAS_ITERATOR_TRAITS 1
to
	#define STANDARD_LIBRARY_HAS_ITERATOR_TRAITS 0

and see what happens.
If that doesn't work, try searching the archives of this group -- I
know this problem has been reported before.

More generally, this should ultimately probably be fixed in the cvisual 
sources, but I'm not sufficiently familiar with C++ myself to suggest
a fix.  Checking out the stl_iterator documentation, I find this about
random_access_iterator:
   
   Defined in the standard header iterator, and in the nonstandard
   backward-compatibility header iterator.h. This class is no longer part
   of the C++ standard, although it was present in early drafts of the
   standard. It is retained in this implementation for backward
   compatibility.

And the header file stl_iterator.h has these lines (at least in my version):

    // The base classes input_iterator, output_iterator, forward_iterator,
    // bidirectional_iterator, and random_access_iterator are not part of
    // the C++ standard.  (they have been replaced by struct iterator.)
    // They are included for backward compatibility with the HP STL.

So it looks like cvisual has run into the problem of shifting
standards :-(.

Anyway, using gcc-2.95 and python-2.2.2 should just work.  Unless
you've got a sense of adventure, I'd try that combination first :-).

Hope this helps,
