Hello
I face this error and I cannot figure out a fix.
I use bjam to build the application code, and inside site-config file, I have also the following a section where I define BOOST_ALL_DYN_LINK:
'''
using gcc : :
        :
where I have defined 
<define> BOOST_ALL_DYN_LINK
'''
I have build boost libraries with the following command:
sudo  bjam toolset=gcc --with-system --with-thread --with-timer --with-chrono --with-filesystem --with-program_options --with-timer --with-log --with-program_options --with-date_time --with-math  --with-serialization --with-regex --with-chrono --with-atomic runtime-link=shared define=BOOST_ALL_DYN_LINK --prefix=/opt/boost_shared install | tee output.txt

I also changed some files (macro definitions and jam files) because I had an error that system and filesystem are configured to be compiled both as static and shared. I compiled them as shared.

When I build the application code, I have plenty of  `boost::log::v2_mt_posix::...` error messages.

Could you give me some guide why this problem exist?

Thanks,
Antonis
