| 编译环境是Ubuntu18.04，遥控器是x9E
记录一下过程。
在安装之前请apt-get update 与 apt-get upgrade
安装库：
apt-get install cmake gcc gcc-avr avr-libc build-essential \? ? libfox-1.6-dev libsdl1.2-dev python-pyqt5 \? ? qt5-default qttools5-dev-tools qtmultimedia5-dev qttools5-dev libqt5svg5-dev \? ? gcc-arm-none-eabi libnewlib-arm-none-eabi libstdc++-arm-none-eabi-newlib?缺少qt5svg：apt-get install??python3-pyqt5.qtsvg
缺少libstdc++-arm-none-eabi-newlib ：vi /etc/apt/sources.list?添加源
deb http://ftp.de.debian.org/debian?sid main
apt-get update
apt-get install?libstdc++-arm-none-eabi-newlib
在Ubuntu18.04 还要装
sudo apt-get install qt5-default qttools5-dev-tools qtmultimedia5-dev qttools5-dev
sudo apt-get install python3-pyside.qtwebkit上面一切顺利的话， 下载源码git clone --recursive -b 2.2?https://github.com.cnpmjs.org/opentx/opentx.git
cd opentx
mkdir build-taranis-debug
cd build-taranis-debug
cmake -DPCB=X9E+ -DGVARS=YES -DLUA=YES -DDEBUG=YES -DCMAKE_BUILD_TYPE=Debug ../
然后会看到

说明配置成功了。
接下来编译固件 make firmware |
