[Boost-users] students_t distribution with mt19937

Hello,

I use some distributions with this code:
boost::normal_distribution<> l_range(p_mean, p_sd);
static boost::mt19937 l_random(static_cast<std::size_t>(time(0)));
boost::variate_generator<boost::mt19937&, boost::normal_distribution<>  
 > l_noise(  l_random, l_range );

I get my value with l_noise() and it works without any problem.

I would like to create now a student_t distribution with
boost::math::students_t_distribution<T> l_range(p_v);
static boost::mt19937 l_random(static_cast<std::size_t>(time(0)));
boost::variate_generator<boost::mt19937&,  
boost::math::students_t_distribution<> > l_noise(  l_random, l_range );

If I run my l_noise() I got a compiler error: error: no match for call  
to  
'(boost::variate_generator<boost::random::mersenne_twister<uint32_t,  
32, 624, 397, 31, 2567483615u, 11, 7, 2636928640u, 15, 4022730752u,  
18, 3346425566u>&, boost::math::students_t_distribution<double,  
boost::math::policies::policy<boost::math::policies::default_policy,  
boost::math::policies::default_policy,  
boost::math::policies::default_policy,  
boost::math::policies::default_policy,

boost::math::policies::default_policy,  
boost::math::policies::default_policy,  
boost::math::policies::default_policy,  
boost::math::policies::default_policy> > >) ()'

Can anyone help me please to understand my mistake while using the  
students_t distribution? I think I need the mt19937 for creating  
random values and the variate_generator to create a "distribution value"

Thanks

Phil
