Re: [Boost-users] [Accumulators][ConceptCheck]: Many warnings for constructing accumulator with density

Roland Bock wrote:

Hi,

the following line results in several kB of warnings:

accumulator_set<double, stats<tag::density > > acc(tag::density::cache_size=10, tag::density::num_bins=5);

include/boost/concept_check.hpp:335: warning: non-static reference 'const double& boost::UnaryFunction<boost::numeric::functional::as_min<const double, void>, double, const double&>::arg' in class without a constructor

gcc-4.2.4, boost-1.41

Am I doing something wrong? Or is there a way to avoid these warnings (other than to turn off warnings)?

Regards,

Roland

PS: It does not seem to be related to tag::density. I get very similar warnings with this accumulator_set<int, stats<tag::min> > acc;
