[Boost-users] Missing libboost_random ?

All, I'm trying to use some of the functions in the boost random library. I get linking errors on: undefined reference to `boost::random_device::random_device(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)' It turns out I do not find any libboost_random.so and none of the installed library has the symbol random_device. Are they missing? Are we not yet supposed to use Boost.Random ? This is the case with both the libraries provided by my distribution (both gentoo and fedora core) as well as a CVS snapshot that I compiled myself. Where are they ? Regards, koen
