px4的开发者手册
https://dev.px4.io/zh/setup/dev_env_linux.html
其中有的shell指令
警告：永远不要使用
sudo来修复权限问题，否则会带来更多的权限问题，需要重装系统来解决。
把用户添加到用户组 "dialout":
sudo usermod -a -G dialout $USER
然后注销后，重新登录，因为重新登录后所做的改变才会有效。
更新包列表，安装下面编译PX4的依赖包。PX4主要支持的系列：
提示：安装Ninja Build System可以比make更快进行编译。如果安装了它就会自动选择使用它进行编译。
sudo add-apt-repository ppa:george-edison55/cmake-3.x -y
sudo apt-get update
# 必备软件
sudo apt-get install python-argparse git-core wget zip python-empy qtcreator cmake build-essential genromfs -y
# 仿真工具
sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt-get install openjdk-8-jre
sudo apt-get install ant protobuf-compiler libeigen3-dev libopencv-dev openjdk-8-jdk openjdk-8-jre 树莓派开发者应该从下面地址下载树莓派Linux工具链。安装脚本会自动安装交叉编译工具链。如果想要用原生树莓派工具链在树莓派上直接编译，参见这里。
git clone https://github.com/pixhawk/rpi_toolchain.git
cd rpi_toolchain
./install_cross.sh
在工具链安装过程中需要输入密码。
如果不想把工具链安装在默认位置/opt/rpi_toolchain，可以执行./install_cross.sh <PATH>向安装脚本传入其它地址。安装脚本会自动配置需要的环境变量。
最后，运行以下命令更新环境变量：
source ~/.profile
以下命令编译生成Raspbian（posix_pi2_release）版本的固件。
cd Firmware
make posix_rpi2_release # for cross-compiler build
"mainapp"可执行文件位于目录build_posix_rpi2_release/src/firmware/posix下。 将其复制到RPi（用你的RPi的IP或主机名替换YOUR_PI，关于如何访问你的RPi，查看介绍)
然后使用以下命令设置你的RPi的IP（或主机名）：
export AUTOPILOT_HOST=192.168.X.X
并上传：
cd Firmware
make posix_rpi_cross upload # for cross-compiler build
然后，通过ssh连接并运行它（以root权限）：
sudo ./px4 px4.config

解决办法：
修改~/.profile,增加环境：
export RPI_TOOLCHAIN_DIR=/opt/rpi_toolchain/gcc-linaro-arm-linux-gnueabihf-raspbian export PATH=$RPI_TOOLCHAIN_DIR/bin:$PATH export AUTOPILOT_HOST=192.168.1.105
然后：
source ~/.profile

这个问题少了jinja2：
sudo apt-get install python-jinja2
