Hello, I am Paul Elliott I am using the AX_BOOST_BASE macro.
My project links to libboost_regex and libboost_filesystem.
I recently found out that in boost version 36, (at least, I am not
sure about the exact cutoff point), I must also link to libboost_system.
boost::system came into existance with boost version 35.
I think the new include files for boost::filesystem also link boost::system.
I distribute to a number of distributions with different versions of
boost.
How do I test for the need to link to boost::system, and add code
that will link to it if needed?
Thank You.
FYI I include my configure.ac:
