Re: [Boost-build] question regarding building with bjam v2

Thanks for getting back to me so quickly.

I'm still looking into this.

It turns out that my Jamfile.v2 contains:

<link>shared:<define>BOOST_SERIALIZATION_DYN_LINK=1

Which turns out to the the "magic" which is provoking the behavior.
I would guess then that I'm building libraries for DLL while boost/test
is perhaps building/testing a static library so this issue doesn't appear.

I don't remember why that line was included in the original Jamfile.  I
did have a lot off difficulty with auto-link because I had one library
wserialization which exports and API but at the same time imports
and API from another library - serialization.  Perhaps that's why
I included that.

So I'll just plug away a while longer.

But I do have a question:If the Jamfile.v2 in the boost root contains
<define>BOOST_ALL_NO_LIB=1 does this mean that for users
the default is auto-linking turned off?  Is that correct?
