undefined reference to symbol ‘pthread_condattr_setclock@@GLIBC_2.3.3‘ 的参考解决方案

写在前面

自己的测试环境：
Ubuntu20.04，PCL 1.10, ROS-Noetic.

一、问题描述

编译PCL 程序的时候报错：

/usr/bin/ld: CMakeFiles/passthrough.dir/src/passthrough.cpp.o: undefined reference to symbol 'pthread_condattr_setclock@@GLIBC_2.3.3'
/usr/bin/ld: /lib/x86_64-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

二、解决方法

可以试试在CMakeLists.txt 增加：

find_package(Boost REQUIRED COMPONENTS system chrono thread)

include_directories( ${Boost_INCLUDE_DIRS})

target_link_libraries(passthrough  ${Boost_LIBRARIES})
