从官网下载mavlink（git clone /mavlink/mavlink.git)
然后进入mavlink 目录执行 git submodule update --init --recursive 下载全部子模块
在本目录下执行python -m mavgenerate 提示：
$ python -m mavgenerateTraceback (most recent call last):File "/usr/lib/python2.7/runpy.py", line 162, in _run_module_as_main"__main__", fname, loader, pkg_name)File "/usr/lib/python2.7/runpy.py", line 72, in _run_codeexec code in run_globalsFile "/home/ev/work/px4/mavlink/mavgenerate.py", line 42, in <module>from pymavlink.generator import mavgenFile "pymavlink/generator/mavgen.py", line 12, in <module>from future import standard_libraryImportError: No module named futureev@Ev-Mayca:~/work/px4/mavlink$ python -m mavgenerateTraceback (most recent call last):File "/usr/lib/python2.7/runpy.py", line 162, in _run_module_as_main"__main__", fname, loader, pkg_name)File "/usr/lib/python2.7/runpy.py", line 72, in _run_codeexec code in run_globalsFile "/home/ev/work/px4/mavlink/mavgenerate.py", line 42, in <module>from pymavlink.generator import mavgenFile "pymavlink/generator/mavgen.py", line 12, in <module>from future import standard_libraryImportError: No module named future
提示没有future模块，解决方案如下
1、安装python3
sudo apt-get install python3
2、安装
sudo apt-get install python3-tk
3、安装pip3
wget https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py
4、执行
sudo pip3 install future
5、执行
python3 -m mavgenerate
6、选择xml文件、选择输出文件夹、选择语言，点击确定
xml选择mavlink/message_definitions/v1.0/common.xml
另外个输出文件夹随便选
语言根据需要选择
7、测试
gcc -I ../../new-mavlink/common/ -o mavlink_udp mavlink_udp.c
编译无错误
我是将输出文件放在mavlink文件夹下的new-mavlink文件夹中
