undefined reference to symbol ‘_ZN5boost6system15system_categoryEv‘

solution¶

The solution found on the Internet is to increase the path of libboost_system.so.

Open the terminal first

locate boost_system
//Find the way to find the file in the directory, and then add it to the file path of cmakelist.
/usr/lib/x86_64-linux-gnu/libboost_system.a
/usr/lib/x86_64-linux-gnu/libboost_system.so
/usr/lib/x86_64-linux-gnu/libboost_system.so.1.58.0

locate boost_filesystem
// find the directory
/usr/lib/x86_64-linux-gnu/libboost_filesystem.a
/usr/lib/x86_64-linux-gnu/libboost_filesystem.so
/usr/lib/x86_64-linux-gnu/libboost_filesystem.so.1.58.0

Then

Link library in CMakeLists file

target_link_libraries(pcd2bin ${PCL_COMMON_LIBRARIES} ${PCL_IO_LIBRARIES}
        /usr/lib/x86_64-linux-gnu/libboost_system.a
        /usr/lib/x86_64-linux-gnu/libboost_system.so
        /usr/lib/x86_64-linux-gnu/libboost_system.so.1.58.0)

The problem is solved, you can use this to understand the general writing of CMakeLists and the compilation process
