Is this perhaps a MS-windows specific problem? I did build a shared lib (using scons, I haven't learned jam yet), and AFAICT it is working, on Linux.
I'm pretty sure you will also run into problems with shared objects under Linux. The problem is that certain global variables (e.g. for the type registry) are defined as static member variables in header files. Under Windows, if two different DLLs include this header file, you will get two different copies of that static member variable - one in each DLL - although there should only be one. Maybe the linker under Linux is smart enough to resolve such issues. Have you tried to serialize a class defined in one shared object (which is registered in the type registry via BOOST_CLASS_EXPORT) from code in another shared object? That's when you might run into problems. You definitely will under Windows. You might also run into problems when you dynamically (i.e. explicitly in your code via dlopen) load a shared object, which contains classes that use BOOST_CLASS_EXPORT to register themselves. Again, under Windows you definitely will.
