使用boost时遇到下面error:
cmake version : 3.5.1
/usr/bin/ld: CMakeFiles/RGBD.dir/src/ros_rgbd.cc.o:
undefined reference to symbol '_ZN5boost6system15system_categoryEv'
/usr/lib/x86_64-linux-gnu/libboost_system.so: error adding symbols:DSO missing from command line
collect2: error: ld returned 1 exit status
原因:libboost_system未被包含
解决:
修改CMakelists.txt:
将 find_package( Boost REQUIRED )
改为 find_package( Boost REQUIRED COMPONENTS filesystem )
注:在cmake2.X中没出现这个问题,在cmake3.X中出现,可能是cmake 修改了相关默认项
