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 '<'")
Your problem is here, but I bet you can find it yourself if you read the docs on extracting results: http://tinyurl.com/2q2ttl (http://boost-sandbox.sourceforge.net/libs/accumulators/doc/html/accumulators...) Hint: feature tags are in the "tags" namespace, but extractors are not. And for the return type of the density extractor, you should look at the docs for density: http://tinyurl.com/3ycetz (http://boost-sandbox.sourceforge.net/libs/accumulators/doc/html/accumulators...) -- Eric Niebler Boost Consulting www.boost-consulting.com
