PX4配置过程与踩坑
0.前言
由于需要在GitHub下载代码,而国内访问受限,可能会出现一些问题,这里建议使用github国内镜像,参看:GitHub国内镜像网站,当然下面会给出具体解决方案。
1.步骤
1.1下载源码:git clone https://github.com/PX4/PX4-Autopilot.git
注意:
若该步骤出错,使用镜像,也就是运行:git clone https://hub.fastgit.xyz/PX4/PX4-Autopilot.git
或者使用gitee镜像:git clone https://gitee.com/robin_shaun/PX4_Firmware
(注意使用这个方法时的源码文件名是PX4_Firmware
)
1.2 切换到源码文件夹:cd PX4-Autopilot
1.3 更新工程子模块git submodule update --init --recursive
注意:
若该步骤出错,归根到底还是因为github访问不稳定。解决方案如下:
(方案的总体原则就是改变源码里面各个.gitmodules
文件里的下载地址,需要注意的是源码位置,我这里是将源码放在主文件夹下,也就是 ~/PX4_Autopilot
)
(1)源码主文件夹下
cd ~/PX4_Autopilot
gedit .gitmodules
(注意:这里主要是为了修改文件,我用的是gedit编辑器,也可以用vim, nano,vs code之类的,后面相同)
将 .gitmodules 中的内容更换为:
[submodule "mavlink/include/mavlink/v2.0"]
path = mavlink/include/mavlink/v2.0

git submodule update --init
(2) libuavcan文件夹
cd ~/PX4_Autopilot/src/drivers/uavcan/libuavcan
gedit .gitmodules
将 .gitmodules 中的内容更换为:
[submodule "dsdl"]
path = dsdl
url = https://gitee.com/robin_shaun/dsdl
branch = legacy-v0
[submodule "libuavcan/dsdl_compiler/pyuavcan"]
path = libuavcan/dsdl_compiler/pyuavcan

[submodule "libuavcan_drivers/kinetis"]
path = libuavcan_drivers/kinetis

git submodule update --init
(3) jMAVSim文件夹
cd ~/PX4_Autopilot/Tools/jMAVSim
gedit .gitmodules
将 .gitmodules 中的内容更换为:
[submodule "jMAVlib"]
path = jMAVlib
url = https://gitee.com/robin_shaun/jMAVlib
branch = master
git submodule update --init
(4) sitl_gazebo文件夹
cd ~/PX4_Autopilot/Tools/sitl_gazebo
gedit .gitmodules
将 .gitmodules 中的内容更换为:
[submodule "external/OpticalFlow"]
path = external/OpticalFlow

[submodule "external/klt_feature_tracker"]
path = external/klt_feature_tracker
url = https://gitee.com/robin_shaun/klt_feature_tracker
git submodule update --init
(8)终于修改完了,可以再次运行下这句命令
git submodule update --init
1.4 编译
cd ~/PX4_Firmware
make px4_sitl_default gazebo
注意:
这一步可能会报错:ninja: build stopped: subcommand failed.
不要慌!
- 先看看子模块是否更新成功。执行命令:
git submodule update --init --recursive
linux哲学,没有消息就是好消息,如果没有出现任何内容,说明子模块更新成功(看不懂什么是子模块也没问题,意思就是到此为止,没问题)。 - 接下来清理下make环境就ok了:
make clean
- 最后再执行一次编译命令:
make px4_sitl_default
以下是我成功的界面
2. 打开gazebo make px4_sitl_default gazebo
注意:
如果gazebo出不来,可以这么做:
- 清理一下:
make distclean
- 重新安装:
sudo apt-get install ros-melodic-gazebo-dev
- 再次运行:
make px4_sitl_default gazebo
