I have just checked out the 'latest' version from cvs.  I notice
that the 'problem' has been fixed.

Thanks

Subject: [Boost-users] pyste and incomplete types

Hi,

I have encountered a problem with pyste and incomplete types.  From earlier
posts and the doco I think that pyste should generate

BOOST_PYTHON_OPAQUE_SPECIALIZED_TYPE_ID(it)

But is does not currently (boost  boost-1.30.2).

invoking bjam without the  BOOST_PYTHON_OPAQUE_SPECIALIZED_TYPE_ID(it)
results
in the output attached (output1)
with BOOST_PYTHON_OPAQUE_SPECIALIZED_TYPE_ID(it) results
in the output attached (output2)

In either case It does not build.  Am I misunderstanding something?

Thanks

Jason
