     Type:  Bugs                        |      Status:  new    
Milestone:  Boost 1.41.0                |   Component:  uBLAS  
  Version:  Boost 1.39.0                |    Severity:  Problem
 Keywords:                              |  
----------------------------------------+-----------------------------------
 Currently I use the ublas concepts defined in ublas/detail/concepts.hpp to
 derive concepts based on ublas concepts such as

 template<class X>
 struct Vector : boost::numeric::ublas::VectorConcept<X>
 {};

 In my unit test project I have different compile units that use
 BOOST_CONCEPT_ASSERT to assure Vector concept compliance. This yields
 multiple defined symbols for the following methods (and full specialized
 versions):

 ublas/detail/concepts.hpp:
 void concept_checks();
 template<class T> ZeroElement(T);
 template<class T> OneElement(T);

 inlining those solves the problem (for me). I'm compiling on MSVC9.0.
 Current trunk seems to have this methods still not-inlined.
