The documentation for chrono says:
"How to Build Boost.Chrono as a Header Only Library?
When BOOST_CHRONO_HEADER_ONLY is defined the lib is header-only.
If in addition BOOST_USE_WINDOWS_H is defined is included,
otherwise files in boost/detail/win are used to reduce the impact of
including .
However, you will either need to define
BOOST_CHRONO_DONT_PROVIDE_HYBRID_ERROR_HANDLING or link with Boost.System. "
So I have:
#define BOOST_CHRONO_HEADER_ONLY
#define BOOST_CHRONO_DONT_PROVIDE_HYBRID_ERROR_HANDLING
#include
followed by some code using chrono, and I still get when linking my exe:
gcc.link
C:\Programming\VersionControl\modular-boost\build\boost\bin.v2\libs\cxx_dual\test\test_chrono.test\gcc-mingw-5.3\debug\test_chrono.exe
C:\Programming\VersionControl\modular-boost\build\boost\bin.v2\libs\cxx_dual\test\test_chrono.test\gcc-mingw-5.3\debug\test_chrono.o:

Is there a way to use chrono without having to link boost::system ?
