pixhawk 固件Firmware内执行make px4fmu-v2_default 编译报错解决办法

执行下列指令报错

make px4fmu-v2_default

/bin/sh: 1: Tools/check_cmake.sh: Permission denied

Makefile:59: *** Fatal.  Stop.

在报错信息里有解决办法：

因为自己的文件不是下载的，是从同事哪里copy来的，所以会报错，自己按照提示信息走了一遍，发现走不通，还是有很多错误。自己才疏学浅，没办法，于是就开始重新按照步骤下载

mkdir -p ~/src
cd ~/src
git clone https://github.com/PX4/Firmware.git
cd Firmware
git submodule update --init --recursive
cd ..

下载完后，终于编译通过了

结束
