#12336: Add Hint to BOOST_ALL_DYN_LINK=1 to serialization library
------------------------------+---------------------------
 Reporter:  georg@…           |      Owner:  ramey
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  serialization
  Version:  Boost 1.61.0      |   Severity:  Problem
 Keywords:  Documentation     |
------------------------------+---------------------------
 When you serialize a class over a pointer and the class is defined in a
 DLL, you need to register the key via BOOST_EXPORT_CLASS(xyz).

 But when you link static, you get two distinct serialization registries
 (extended_type_info) and the main executable cant serialize/deserialize
 the class in the DLL.

 When you compile with BOOST_ALL_DYN_LINK=1 and dynamicaly link to the
 boost libs, this ensures that there is just one registry
 (extended_type_info).

 So i would add this hint in the "Tips & Tricks" section or in the page of
 the derived classes.

 BOOST_ALL_DYN_LINK=1 is important for the serialization. This ensures
 that there is just one extended_type_info registry. Otherwise the
 main executable cant de/serialize the objects in the DLL/so file.
