[Boost-users] [Chrono][System]:header only Boost.Chrono is not working with header only Boost.System

Hi, On RHEL 5.5 Boost.Chrono 1.1.0 (Boost 1.47.0) fails to run in header only mode with header only Boost.System. This file can't be compiled: #define BOOST_SYSTEM_NO_DEPRECATED // without it also error, but in [Boost.System] #define BOOST_SYSTEM_INLINED #define BOOST_CHRONO_HEADER_ONLY #include int main() { boost::chrono::steady_clock::time_point start = boost::chrono::steady_clock::now(); return 0; } Error: In function `boost::chrono::steady_clock::now()': boost/chrono/detail/inlined/posix/chrono.hpp:85: undefined reference to `boost::system::system_category()' Any comments from Chrono\System guys? Thanks, Dmitriy.
