[100%] Linking CXX executable /home/yahboom/dev/catkin_ws/devel/lib/hector_mapping/hector_mapping [100%] Built target hector_mapping

这是一个 CMake 编译过程的输出结果。该命令编译了一个名为 "hector_mapping" 的可执行文件，并将其存储在 "/home/yahboom/dev/catkin_ws/devel/lib/hector_mapping" 目录中。具体输出结果如下：

- `[100%] Linking CXX executable /home/yahboom/dev/catkin_ws/devel/lib/hector_mapping/hector_mapping` 表示编译过程已经完成，并且正在将 C++ 代码编译为可执行文件 "hector_mapping"。
- `[100%] Built target hector_mapping` 表示 CMake 成功地构建了名为 "hector_mapping" 的目标，并且该目标已经被构建完成。该目标可以被链接到其他程序中，或者直接被执行。

Linking CXX executable /home/zmc/catkin_ws/devel/lib/gmapping/slam_gmapping /opt/ros/melodic/lib/libtf.so：对‘tf2_ros::TransformListener::TransformListener(tf2::BufferCore&, ros::NodeHandle const&, bool)’未定义的引用 collect2: error: ld returned 1 exit status slam_gmapping/gmapping/CMakeFiles/slam_gmapping.dir/build.make:166: recipe for target '/home/zmc/catkin_ws/devel/lib/gmapping/slam_gmapping' failed make[2]: *** [/home/zmc/catkin_ws/devel/lib/gmapping/slam_gmapping] Error 1 CMakeFiles/Makefile2:7904: recipe for target 'slam_gmapping/gmapping/CMakeFiles/slam_gmapping.dir/all' failed make[1]: *** [slam_gmapping/gmapping/CMakeFiles/slam_gmapping.dir/all] Error 2 Makefile:140: recipe for target 'all' failed make: *** [all] Error 2 Invoking "make -j1 -l1" failed

这个错误通常表示您的程序在链接时找不到所需的库文件。在这种情况下，它似乎找不到名为libtf.so的库文件。

要解决这个问题，您可以尝试以下几个步骤：

1. 确保您已经安装了tf库。您可以在终端中运行以下命令来安装它：

   sudo apt-get install ros-melodic-tf

2. 检查您的CMakeLists.txt文件是否正确设置了链接库。您可以添加以下行来链接tf库：

   target_link_libraries(slam_gmapping ${catkin_LIBRARIES} tf)

3. 如果tf库已正确安装并且CMakeLists.txt文件已正确设置，但问题仍然存在，请尝试清理和重新构建您的工作区。您可以在终端中执行以下命令来清理构建文件：

   catkin clean

然后重新构建：

   catkin build

这些步骤应该有助于解决链接错误并成功构建您的程序。如果问题仍然存在，请提供更多信息，以便我们可以更好地帮助您解决问题。
