I tried to experiment with boost::random_device (e.g. http://www.boost.org/doc/libs/1_42_0/libs/random/nondet_random_speed.cpp), but failed to link it:

randomTest.cpp:36: undefined reference to `boost::random_device::operator()()' randomTest.o: In function `main': randomTest.cpp:57: undefined reference to `boost::random_device::default_token' randomTest.cpp:57: undefined reference to `boost::random_device::random_device(std::basic_string const&)' randomTest.cpp:63: undefined reference to `boost::random_device::~random_device()'

There seems to be a boost_random library missing.

I am using Ubuntu-8.04, 64bit with gcc-4.2.4.

There's a trac ticket for this. In the interim, the implementation is in libs/random/random_device.cpp. In Christ, Steven Watanabe
