Hello all, I am attempting to use the non-deterministic random number generator class contined in boost::random and have encountered the following errors upon running the program. The program does compile without errors, and I am using KDevelop 2.1.3 in the RedHat Linux 8.0 environment. Here's the offending code: #include <iostream> #include <cstdlib> #include int main() { boost::random_device dev; return EXIT_SUCCESS; } I receive the following error message: /home/JAgiato/boosttest/boosttest/main.cpp:6: undefined reference to `boost::random_device::default_token' /home/JAgiato/boosttest/boosttest/main.cpp:6: undefined reference to `boost::random_device::random_device[in-charge](std::basic_string const&)' /home/JAgiato/boosttest/boosttest/main.cpp:8: undefined reference to `boost::random_device::~random_device [in-charge]()' My goal is to use this class to produce non-deterministic 32 bit integers which will be streamed to a binary file. Any help is greatly apprechiated! Thank you! Jon Agiato JonAgiato@nyc.rr.com [Non-text portions of this message have been removed]
