Re: [Boost-users] [Accumulators] How to define the initial value ?

It should be as simple as using the "sample" keyword in the boost::accumulators namespace, like:

using namespace boost::accumulators; accumulator_set< int, featurestag::weighted_sum > acc( sample = 42 )

Thanks Eric. Indeed, it works ! But my problem was actually independent of this. I am using more features, and it seems that we can't use more than 4 tagged arguments !!! <snip>

I wanted acc2, so I thought my syntax using the "sample" keyword was wrong but it was not, as acc3 and acc4 do compile. Is that a bug ? <snip>

Sounds like it. Could you try defining BOOST_PARAMETER_MAX_ARITY to be something higher, like 10? -- Eric Niebler BoostPro Computing http://www.boostpro.com
