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。
