[1%] Building CXX object clbrobot_project/clb_pid/CMakeFiles/pid_listen.dir/src/clbrobot_pid_core.cpp.o
In file included from /home/ubuntu/noetic/catkin_ws/src/clbrobot_project/clb_pid/src/clbrobot_pid_core.cpp:1:
/home/ubuntu/noetic/catkin_ws/src/clbrobot_project/clb_pid/include/clbrobot_pid/clbrobot_pid_core.h:8:10: fatal error: clb_msgs/PID.h: No such file or directory
8 | #include "clb_msgs/PID.h"
|^~~~~~~~~~~~~~~~
compilation terminated.

说明：这个PID.h是由clb_msgs项目生成的，如果这个项目没有在clb_pid项目前编译，就会出现这个问题。
解决办法：
首先单独编译这个包，

catkin_make -DCATKIN_WHITELIST_PACKAGES="clb_msgs"

然后再编译全部的包，

catkin_make -DCATKIN_WHITELIST_PACKAGES=""

这样，程序就能正确链接了。

packet_write_wait: Connection to 192.168.3.93 port 22: Broken pipe
进入服务器，

sudo vim /etc/ssh/sshd_config

将下面的参数修改一下，

ClientAliveInterval 60

重启一下，

systemctl restart sshd

完成。

下面这个问题参考这位小哥的贴子：
??编译ros_astra_camera 出现找不到libucv问题，已经解决_顺德龙卷风的博客-CSDN博客??
除了问题报错，基本照抄，如下，
编译ros_astra_camera 包的时候会出现一大段报错问题，这样的一堆…

看一下就是找不到库的问题，解决这个问题的方法是修改ros_astra_camera的CmakeList.txt文件。（入行小白一开始很头大，因为不熟悉Cmake语法，后来看了几天之后凭感觉学会了，我真是个天才，哈哈飘了）咳咳，直接关注问题本身。
Cmakelist中的添加libuvc是通过find_package(libuvc REQUIRED) 寻找库的，但是新安装的libuvc 0.0.6 没有生成 libuvc.cmake文件（不知道原因），所以编译时libuvc_INCLUDE_DIRS、libuvc_LIBRARIES 都是空的！！！所以编译才找不到对应的库！
解决办法:在ros_astra_camera的CmakeList.txt文件的find_package(libuvc REQUIRED)下方添加两条语句（根据你libuvc安装的地址修改），编译就OK了
set(libuvc_INCLUDE_DIRS “/usr/local/include/libuvc”)
set(libuvc_LIBRARIES “/usr/local/lib/libuvc.so”)

find_package(libuvc REQUIRED) #原因是libuvc库存在问题,没有libuvc.cmake文件,find_package()无法找到libuvc库文件
#解决办法手动添加库文件位置
set(libuvc_INCLUDE_DIRS "/usr/local/include/libuvc")
set(libuvc_LIBRARIES "/usr/local/lib/libuvc.so")

解决此问题后还有一个无法看在 rviz 中看到 RGB图像的问题，参考这位小哥的博客他找到了bug并解决了（官方驱动包有问题）
