Thank you Eric, it now compiles fine.
However, I am still having problem to acces the histogram :

typedef iterator_range<std::vector<std::pair<double, double> >::iterator 
 > histogram_type;
                                        histogram_type histogram = 
tag::density(angular_acc); // error C2143: erreur de syntaxe : absence 
de ';' avant '<' (--> "syntax error : missing ';' before '<'")
 
                                         for (std::size_t i = 0; i < 
histogram.size(); ++i)
                                         {  
                                             // problem with small 
results: epsilon is relative (in percent), not absolute!
                                             if ( histogram[i].second > 
0.001 )   
                                                 BOOST_CHECK_CLOSE( 0.5 
* (1.0 + erf( histogram[i].first / sqrt(2.0) )), histogram[i].second, 
epsilon );
                                         } 

Could you help me ?

Regards

Olivier
