Comment (by Aaron Barany <akb825@…>):

 I have attached a simple tester to demonstrate the issues with DLL
 linking. (test dll.zip) This tester defines a separate archive (just a
 copy of text_iarchive) and demonstrates how it will not compile with
 unpatched boost, but will compile once my patches are applied. I detailed
 why this is the case in comment 5.

 If you want to use the solution and project files I provided, first you'll
 have to have Visual Studio 2010 installed. If you don't own Visual Studio
 2010, you can download the free express version here.
 (http://www.microsoft.com/express/Downloads/#2010-Visual-CPP) It should
 install beside any existing Visual Studio installation gracefully.
 Additionally, you can re-use my source files and set up the project
 yourself, making sure it links to the DLL build of boost.

 I set up my project assuming you're compiling boost with the following
 bjam parameters:
 variant=debug link=shared threading=multi address-model=32
 --toolset=msvc-10.0 stage

 To compile the test, extract "test dll.zip" in the "libs\serialization"
 directory. Open the "test dll.sln" solution and build with the debug/win32
 configuration. With unpatched boost, it fails with the following errors:\\
 1>c:\users\abarany.navteq\desktop\boosttest\boost_1_46_1\boost\archive\impl\archive_serializer_map.ipp(45):
 error C2491:
 'boost::archive::detail::archive_serializer_map<Archive>::insert' :
 definition of dllimport function not allowed\\
 1>c:\users\abarany.navteq\desktop\boosttest\boost_1_46_1\boost\archive\impl\archive_serializer_map.ipp(57):
 error C2491:
 'boost::archive::detail::archive_serializer_map<Archive>::erase' :
 definition of dllimport function not allowed\\
 1>c:\users\abarany.navteq\desktop\boosttest\boost_1_46_1\boost\archive\impl\archive_serializer_map.ipp(67):
 error C2491:
 'boost::archive::detail::archive_serializer_map<Archive>::find' :
 definition of dllimport function not allowed

 If you apply my patches and rebuild boost, when you rebuild the test dll
 solution the build should succeed.
