libgrasp_candidates_generator.so：对‘boost::this_thread::hidden::sleep_until(timespec const&)’未定义的引用

[nuo-code]

Hello, I encountered an error when using your library，libgrasp_candidates_generator.so：对‘boost::this_thread::hidden::sleep_until(timespec const&)’未定义的引用，My boost library version is 1.65.1，Can you give me some help？

I had a similar problem and was able to resolve it by adding the following include directive to src/gpg/plot.cpp:

#include <boost/thread/thread.hpp>

After this I still had some linking errors for Boost libraries:

/usr/bin/ld: libgrasp_candidates_generator.so: undefined reference to `boost::this_thread::interruption_point()'
/usr/bin/ld: libgrasp_candidates_generator.so: undefined reference to `boost::detail::get_current_thread_data()'

I resolved these errors by adding the following lines to my CMakeLists.txt:

# Boost
find_package(Boost REQUIRED COMPONENTS thread)
include_directories(${Boost_INCLUDE_DIR})
link_directories(${Boost_LIBRARY_DIRS})
add_definitions(-DBOOST_ALL_DYN_LINK)

# after add_executable() with the other target_link_libraries()
target_link_libraries(${PROJECT_NAME}_grasp_candidates_generator ${Boost_LIBRARIES})

I do not know if this is the correct solution to this problem nor have I tested the library yet but it allowed me to finish the build without errors. I am on Ubuntu 20.04 with Boost 1.71.

I am very glad to receive your reply, I have solved this mistake, my Ubuntu version is 18.04, I changed the Boost version to 1.53 is correct.This error was encountered earlier because the Boost version was too high.
