Re: [Boost-users] Problem with boost 1.36, vs2005 and serialization library -> linker problem

I've always had problems with BOOST_CLASS_EXPORT.  The issues
of been of various character from the concept of what it does and/or
should do, how it should/should not be used, and how it is implemented.

In 1.36, I spend some time considering BOOST_CLASS_EXPORT
more carefully and have updated the documentation regarding its
usage.  I would suggest taking a look at the 1.36 documentation
regarding BOOST_CLASS_EXPORT and checking the code
to verify that it follows the recommendations in the current
documentation.
