Today, I tried to build Boost.Log on Arch Linux, but encountered following errors:
......
undefined reference to `boost::log::v2s_mt_posix::aux::stream_provider<char>::allocate_compound(boost::log::v2s_mt_posix::record&)'

After some investigation, I find at least on Arch Linux, some modules need to be specified explicitly (E.g., log) while some not (E.g., graph). Besides, I also need claim that I want static library:
SET(Boost_USE_STATIC_LIBS ON)
FIND_PACKAGE(Boost REQUIRED COMPONENTS log)
Then use Boost_LIBRARIES in linking executable file:
TARGET_LINK_LIBRARIES(... ${Boost_LIBRARIES})

Thanks for that. After reading many, many pages on this problem, your answer was the only one that worked. I also had to insert
SET (CMAKE_C_FLAGS “-Wall -std=c++14 -fvisibility=hidden -fvisibility-inlines-hidden”)
to get rid of most of the “direct access in function ‘boost::log…” messages. Unfortunately some of them are still here.
