k.t., I tried your code and it worked, so I pinpointed my problem to bad type conversion. Thanks a lot! Ksenia --- In Boost-Users@yahoogroups.com, "k.t." <kohske@m...> wrote:

Hi,

I am using boost_1_29_0 to implement random distribution functions. The standard download included implementation of uniform, normal and exponential distributions - and they work great. I also need an implementation of poisson distribution, and I have noticed that poisson_distribution.hpp was added to CVS last October. I got the file, and put it into the boost/random/ directory, with the other random distribution files.

However, when I try using poisson distribution, I get a series of 0's instead of a series of random numbers, although I'm using it exactly the same way as with the other distributions.

I am not sure whether the problem is due to incorrect installation of the new file, or due to bugs in the implementation. I tried cleaning the boost_1_29_0 directory, and running bjam again, but still no luck. Is there anything else I should do to include this new header file?

Any help would be greatly appreciated.

Thank you, Ksenia

In my environment (gcc 3.2 + cygwin.), it does work only by including the new header.

--exp-- #include <boost/random.hpp> #include <boost/random/poisson_distribution.hpp> #include <iostream> int main(){ boost::lagged_fibonacci607 lf; boost::poisson_distribution<boost::lagged_fibonacci607> nd(lf,5); for(int i=0;i<100;++i) std::cout << nd() << ", "; std::cout << std::endl; }

--result-- 2, 2, 3, 1, 1, 0, 1, 2, 1, 2, 2, 2, 0, 0, 1, 0, 0, 0, 1, 1, 2, 1, 0, 2, 2, 1, 0, 0, 1, 0, 1, 2, 2, 0, 0, 3, 1, 2, 0, 4, 1, 0, 0, 1, 3, 1, 0, 0, 1, 1, 1, 0, 2, 0, 0, 1, 0, 1, 0, 2, 0, 2, 1, 3, 1, 1, 1, 1, 0, 1, 1, 1, 1, 0, 0, 0, 5, 1, 1, 1, 2, 0, 1, 0, 1, 2, 0, 0, 2, 0, 1, 0, 0, 0, 0, 1, 1, 2, 1, 1, --
