Building an Executable that Uses Boost.Chrono

In addition to link with the Boost.Chrono library you need also to link with the Boost.System library. Once Boost.System will be configurable to be a header only using BOOST_SYSTEM_INLINED you will no need to link with it.

Thanks,

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 <boost/chrono.hpp>

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?

Hi,

unfortunately the patch proposed to make Boost.System header only was not accepted.

So even if Boost.Chrono is header-only it depends on a library that is not :(

Best,
Vicente
