--- Comment #8 from Paolo Carlini <paolo.carlini at oracle dot com> ---
To further clarify, the problem is that hypergeometric_distribution is using:
std::__detail::_Adaptor<_UniformRandomNumberGenerator, result_type>
__aurng(__urng);
where result_type is an *integer* type, and that is not Ok, because _Adaptor
just forwards to generate_canonical, which wants a *floting point* type as
first template argument. I suspect that something as simple as:
std::__detail::_Adaptor<_UniformRandomNumberGenerator, double>
__aurng(__urng);
could be most of the fix (in a couple other places, for discrete distributions,
I ended up using _Adaptor exactly like that) but the implementor (ie, Ed) of
hypergeometric_distribution should really look into it.
Eventually, we should remember to add a static_assert to _Adaptor of the form:
static_assert(std::is_floating_point<_DInputType>::value,
"template argument not a floating point type");
Ed, can you please have a look?
