I am trying to compile the Point Cloud library from a source in OSX 10.6.8, and I continue to work against the same error with Boost libraries:
! make Linking CXX shared library ../lib/libpcl_common.dylib Undefined symbols: "boost::thread::start_thread_noexcept()", referenced from: boost::thread::thread<boost::_bi::bind_t<void, boost::_mfi::mf0<void, pcl::TimeTrigger>, boost::_bi::list1<boost::_bi::value<pcl::TimeTrigger*> > > >(boost::_bi::bind_t<void, boost::_mfi::mf0<void, pcl::TimeTrigger>, boost::_bi::list1<boost::_bi::value<pcl::TimeTrigger*> > >, boost::disable_if_c<boost::thread_detail::is_convertible<boost::_bi::bind_t<void, boost::_mfi::mf0<void, pcl::TimeTrigger>, boost::_bi::list1<boost::_bi::value<pcl::TimeTrigger*> > >&, boost::detail::thread_move_t<boost::_bi::bind_t<void, boost::_mfi::mf0<void, pcl::TimeTrigger>, boost::_bi::list1<boost::_bi::value<pcl::TimeTrigger*> > > > >::value, boost::thread::dummy*>::type)in time_trigger.cpp.o "boost::thread::join_noexcept()", referenced from: pcl::TimeTrigger::~TimeTrigger()in time_trigger.cpp.o ld: symbol(s) not found collect2: ld returned 1 exit status make[2]: *** [lib/libpcl_common.1.7.0.dylib] Error 1 make[1]: *** [common/CMakeFiles/pcl_common.dir/all] Error 2 make: *** [all] Error 2
I looked at the CMake options and , none of them seem to reference the Boost library with the advanced settings activated, I found that my boost library files are in /usr/lib/ ; e.g. /usr/lib/libboost_date_time-mt.dylib :
What can I do to solve this problem? And what can I do in the future to prevent the recurrence of such problems?
UPDATE I rebuilt and compiled Boost from scratch and I still get the same error. This seems very strange, since Boost is compiled from scratch, and PCL too. The only thing that can be noted is the CMake output, I get this strange conflicting message:
-- checking for module 'eigen3' -- package 'eigen3' not found -- Eigen found (include: /usr/local/include/eigen3)
