px4源码编译指南

px4源码编译指南

强烈推荐大家去看官网的英文文档，国内的博客杂七杂八，官网的中文也很久没有更新，这几天自己踩了很多坑，写个教程希望能帮助到大家（本文选用平台是pixhawk1)

1. 安装ubuntu16.04

18.04版本似乎是没有适配的工具链，编译的时候莫名其妙会报错，所以直接安装16的版本

2. 换源

ubuntu默认是欧洲的源，速度慢的惊人，推荐换成阿里的镜像

1）先备份一下

cp /etc/apt/sources.list /etc/apt/sources.list_bak

2）编辑sources.list

sudo gedit /etc/apt/sources.list

3）将所有内容替换成以下代码

#deb cdrom:[Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial main restricted
deb-src http://archive.ubuntu.com/ubuntu xenial main restricted #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe
deb http://mirrors.aliyun.com/ubuntu/ xenial multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse #Added by software-properties
deb http://archive.canonical.com/ubuntu xenial partner
deb-src http://archive.canonical.com/ubuntu xenial partner
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-security multiverse

4)最后记得更新

sudo apt-get update

参考：https://www.cnblogs.com/mufire/p/6433757.html

3. 编译环境搭建

1）

 sudo usermod -a -G dialout $USER

2）注销账户后再登录一次
3）下载工具链配置脚本并安装

 wget https://raw.githubusercontent.com/PX4/Devguide/master/build_scripts/ubuntu_sim_nuttx.sh
 source ubuntu_sim_nuttx.sh

4）重启一次系统

4. 安装仿真器

 wget https://raw.githubusercontent.com/PX4/Devguide/master/build_scripts/ubuntu_sim_common_deps.sh
 source ubuntu_sim_common_deps.sh

5. 编译源码（基于pixhawk1)

1）下载源文件

git clone https://github.com/PX4/Firmware.git

2）编译仿真器(在虚拟机上会失效，只能实际装一个系统，不过不影响编译源码，只是不能模拟了）

make px4_sitl jmavsim

3）编译

make make px4_fmu-v2_default

如果出现类似下面的句子，说明编译成功

[954/954] Creating /home/youruser/src/Firmware/build/px4_fmu-v2_default/px4_fmu-v2_default.px4

4）编译好后上传

make make px4_fmu-v2_default upload

出现下面这种应该就成功了，和官网上的样式不太一样

Erase : [====================] 100.0%
Program: [====================] 100.0%
Verify : [====================] 100.0%
Rebooting. Elapsed Time 44.948

6. 配置IDE

官方推荐的IDE是QT，刚才的脚本已经下载了qtcreator
QT配置可以参考：https://blog.csdn.net/pix_csdn/article/details/81913610
