Usually, this means you have a reference of your libshark.so.2.3.0 to
libboost_test_exec_monitor-mt.a, but in this case, your manually set up
link line wouldn't work, too, so are you sure that line works as you've
presented it, i.e. with -lboost_test_exec_monitor-mt before -lshark?
Does SET(LINK_LIBRARIES shark ${Boost_TEST_EXEC_MONITOR_LIBRARY}),
i.e. shark-before-boost, work?
Another potential cause for such incidents is the use of different C++
compiler versions, so do you have multiple compilers installed, or do
you have multiple Boost installations, and how does libshark.so.2.3.0
get built?
