ERROR in building the convex_plane_decomposition_ros

[ajxdhe]

Ubuntu 20.04
ROS noetic

when I ran catkin build convex_plane_decomposition_ros It occured

/usr/include/boost/parameter/config.hpp:61: note: this is the location of the previous definition 61 | #define BOOST_PARAMETER_MAX_ARITY BOOST_MPL_LIMIT_VECTOR_SIZE | /usr/bin/ld: CMakeFiles/convex_plane_decomposition_ros_TestShapeGrowing.dir/test/TestShapeGrowing.cpp.o: undefined reference to symbol '__gmpn_com' /usr/bin/ld: /lib/x86_64-linux-gnu/libgmp.so.10: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status make[2]: *** [CMakeFiles/convex_plane_decomposition_ros_TestShapeGrowing.dir/build.make:227：/home/skywalker/quardroped/devel/.private/convex_plane_decomposition_ros/lib/convex_plane_decomposition_ros/convex_plane_decomposition_ros_TestShapeGrowing] 错误 1 make[1]: *** [CMakeFiles/Makefile2:225：CMakeFiles/convex_plane_decomposition_ros_TestShapeGrowing.dir/all] 错误 2 make[1]: *** 正在等待未完成的任务.... make: *** [Makefile:141：all] 错误 2

Wish you could help me to solve this issue ,thanks

错误原因是因为在链接阶段，编译器无法解释"__gmpn_com"的引用，并在连接libgmp库时出问题。

在convex_plane_decompositon_ros 包的CMakeList.txt文件的target_link_libraries中末尾添加“-lgmp”
