ROS小车一些错误解决

sudo apt-get install ros-melodic-serial

18.04是melodic

---

---

sudo apt-get install ros-melodic-uuid-msgs

---

---

sudo apt-get install ros-melodic-bfl

---

---

lslidar功能包的cmakelist文件的boost搞成Boost。

---

---

sudo apt-get install ros-melodic-joy

---

---

sudo apt-get install libpcap-dev

---

---

先编译lslidar_msgs

catkin_make -DCATKIN_WHITELIST_PACKAGES=lslidar_msgs

---

---

sudo apt-get install ros-melodic-gmapping

---

---

rviz失败：

libEGL warning: DRI2: failed to authenticate

在ubuntu底下rviz，不要在树莓派底下。

中间那个错误是少world_canvas_msgs包

下面那个不清楚，突然解决，听说是多开roscore要重新source devel/setup.bash

最上面那个还不清楚

解决，就是雷达的包没编译好，

catkin_make -DCATKIN_WHITELIST_PACKAGES="lslidar_msgs"

catkin_make -DCATKIN_WHITELIST_PACKAGES="lslidar_driver"

然后source devel/setup.bash一下。

后面开始装车测试建图效果
