Subject: Query on Boost.Log
Hi everyone,
I’m trying to learn how to use Boost.Log from Boost 1.54.0 on Fedora 18.
When I attempt to call boost::log::init_from_stream() even with BOOST_LOG_DYN_LINK defined, I get the error message”undefined reference to `void boost::log::v2_mt_posix::init_from_stream<char>(std::basic_istream&)'” for the line where I called the function. Note that I have included the header file “boost/log/utility/setup/from_stream.hpp” and added –lboost_log to my link command line.
Am I missing something. I have noticed that boost::log::init_from_stream() is a template. Is an instance of this template added into the shared library?
Kind regards,
Leo
Hi again everyone,
FYI.
I built Boost 1.54.0 using the following bjam options – link=shared runtime-link=shared
I have also checked the build logs from the above and discovered that not all of the .cpp files in libs/log/src have been included during the build.
Kind regards,
Leo
