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})
