Trying to use OMPL 1.1.0 library. I'm using this sample code (not really relevant to the problem, which happens at runtime):

#include <ompl/base/Goal.h>
#include <ompl/base/goals/GoalState.h>
#include <ompl/base/goals/GoalStates.h>
#include <ompl/base/ProjectionEvaluator.h>
#include <ompl/base/StateSpace.h>
#include <ompl/geometric/PathSimplifier.h>
#include <ompl/base/samplers/UniformValidStateSampler.h>

#include <ompl/base/spaces/RealVectorStateSpace.h>
#include <ompl/base/spaces/SE2StateSpace.h>
#include <ompl/base/spaces/SE3StateSpace.h>

#include <ompl/geometric/SimpleSetup.h>
#include <ompl/geometric/planners/rrt/RRT.h>

#include <boost/make_shared.hpp>
#include <boost/shared_ptr.hpp>

#include <iostream>

namespace ob = ompl::base;
namespace og = ompl::geometric;

bool isStateValid(const ob::State *state)
{
    return true;
}

int main(int /*argc*/, char ** /*argv*/)
{
    std::cout << "OMPL version: " << OMPL_VERSION << std::endl;
    boost::shared_ptr<ob::SE3StateSpace> space(boost::make_shared<ob::SE3StateSpace>());
    ob::RealVectorBounds bounds(3);
    bounds.setLow(-1);
    bounds.setHigh(1);
    space->setBounds(bounds);
    og::SimpleSetup ss(space);
    //ss.setStateValidityChecker([](const ob::State *state) { return isStateValid(state); });
    ob::ScopedState<> start(space);
    start.random();
    ob::ScopedState<> goal(space);
    goal.random();
    ss.setStartAndGoalStates(start, goal);
    ss.setup();
    ss.print();
    ob::PlannerStatus solved = ss.solve(1.0);
    if(solved)
    {
        std::cout << "Found solution:" << std::endl;
        ss.simplifySolution();
        ss.getSolutionPath().print(std::cout);
    }
    else
        std::cout << "No solution found" << std::endl;
    return 0;
}

and the following makefile:

CXXFLAGS=-I/usr/local/Cellar/ompl/1.1.0/include -I/usr/local/Cellar/boost/1.64.0_1/include
LDLIBS=-lc++ -L/usr/local/Cellar/boost/1.64.0_1/lib/ -lboost_thread-mt -lboost_filesystem -lboost_system -lompl
ompltest: ompltest.o

when I run the executable I get:

dyld: lazy symbol binding failed: Symbol not found: __ZN5boost11this_thread5hiden11sleep_untilERK8timespec
  Referenced from: /usr/local/opt/ompl/lib/libompl.11.dylib
  Expected in: /usr/local/opt/boost/lib/libboost_thread-mt.dylib

dyld: Symbol not found: __ZN5boost11this_thread5hiden11sleep_untilERK8timespec
  Referenced from: /usr/local/opt/ompl/lib/libompl.11.dylib
  Expected in: /usr/local/opt/boost/lib/libboost_thread-mt.dylib

Abort trap: 6

I look for the missing symbol in the boost shared library, and I find:

$ nm -gU /usr/local/opt/boost/lib/libboost_thread-mt.dylib | grep sleep_until.*timespec
0000000000004130 T __ZN5boost11this_thread21no_interruption_point6hidden11sleep_untilERK8timespec
0000000000004390 T __ZN5boost11this_thread6hidden11sleep_untilERK8timespec

there is __ZN5boost11this_thread6hidden11sleep_untilERK8timespec and not __ZN5boost11this_thread5hiden11sleep_untilERK8timespec . what is that? a typo? or intended? the point is that I cannot use this library which I didn't even build by myself (installed via homebrew)

EDIT: unmangled symbol names:

$ nm -jgU /usr/local/opt/boost/lib/libboost_thread-mt.dylib | grep sleep_until.*timespec | c++filt
boost::this_thread::no_interruption_point::hidden::sleep_until(timespec const&)
boost::this_thread::hidden::sleep_until(timespec const&)
$ echo __ZN5boost11this_thread5hiden11sleep_untilERK8timespec | c++filt
boost::this_thread::hiden::sleep_until(timespec const&)

    Pass your symbols through `c++filt` or the equivalent on your system and then paste those names into your question. – John Zwinck Jun 04 '17 at 11:43

As suggested by John Zwinck

echo __ZN5boost11this_thread5hiden11sleep_untilERK8timespec |c++filt boost::this_thread::hiden::sleep_until(timespec const&) echo __ZN5boost11this_thread6hidden11sleep_untilERK8timespec |c++filt boost::this_thread::hidden::sleep_until(timespec const&) Perhaps your /usr/local/opt/ompl/lib/libompl.11.dylib was built using different version of boost library then your current 1.64 ? What boost library was used to build OMPL ?
