Linux 35.5 + JetPack v5.1.3@ego-planner-swarm编译安装

本文主要是介绍Linux 35.5 + JetPack v5.1.3@ego-planner-swarm编译安装，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1. 源由

• Linux 35.5 + JetPack v5.1.3@ ego-planner编译安装

ego-planner 是一个单机版本，而ego-planner-swarm是一个多级飞行的版本，因此在此一起学习下，以便更好的理解该系列开源项目的整个进展和框架。

2. 编译&安装

• 确认本地ROS版本：

$ rosversion --distro
noetic

• 本次编译代码版本：

$ git log -n 1
commit 30de3c9e11e6a2e06d81561f9364f07ceba6774b (HEAD -> master, origin/master, origin/HEAD)
Author: Xin Zhou <923137104@qq.com>
Date:   Thu Mar 16 21:00:03 2023 +0800Update README.md

• 系统安装不再赘述，详见：Linux 35.5 + JetPack v5.1.3@ros-noetic安装

Step 1：依赖库安装

$ sudo apt-get install libarmadillo-dev

Step 2：建立工程

$ mkdir -p ${YOUR_WORKSPACE_PATH}/src
$ cd ${YOUR_WORKSPACE_PATH}/src
$ git clone git@github.com:ZJU-FAST-Lab/ego-planner-swarm.git

Step 3：编译工程

$ cd ego-planner-swarm
$ catkin_make -j1

或者

$ cd ego-planner
$ catkin_make -DCMAKE_BUILD_TYPE=Release -j1

Step 4：安装工程

略，因为暂时不涉及软件的部署应用，相关模拟命令参考：

$ source devel/setup.bash && roslaunch ego_planner simple_run.launch

或者

1. 运行Rviz虚拟环境

$ source devel/setup.bash
$ roslaunch ego_planner rviz.launch

2. 运行模拟程序

$ source devel/setup.bash
$ roslaunch ego_planner swarm.launch

3. 问题汇总

3.1 组件ros-noetic-roslint问题

-- +++ processing catkin package: 'drone_detect'
-- ==> add_subdirectory(planner/drone_detect)
-- Could NOT find roslint (missing: roslint_DIR)
-- Could not find the required component 'roslint'. The following CMake error indicates that you either need to install the package with the same name or change your environment so that it can be found.
CMake Error at /opt/ros/noetic/share/catkin/cmake/catkinConfig.cmake:83 (find_package):Could not find a package configuration file provided by "roslint" with anyof the following names:roslintConfig.cmakeroslint-config.cmakeAdd the installation prefix of "roslint" to CMAKE_PREFIX_PATH or set"roslint_DIR" to a directory containing one of the above files.  If"roslint" provides a separate development package or SDK, be sure it hasbeen installed.
Call Stack (most recent call first):planner/drone_detect/CMakeLists.txt:12 (find_package)-- Configuring incomplete, errors occurred!

**解决方案：**安装组件ros-noetic-roslint

$ sudo apt-get install ros-noetic-roslint

**解决方案：**更换编译命令

$ catkin_make

4. 总结

本次顺利实现了Jetson Orin Nano上的模拟导航飞行，同时看到有模拟的飞机遇到障碍没有飞出来，具体问题待进一步的研究了。
