PX4/固件出错

Question

问题：当我运行make px4fmu-v2_default时，我得到的是：

rootroot:~/Firmware$ make px4fmu-v2_default
Makefile:44: Not a valid CMake version or CMake not installed.
Makefile:45: On Ubuntu, install or upgrade via:
Makefile:46: 
Makefile:47: 3rd party PPA:
Makefile:48: sudo add-apt-repository ppa:george-edison55/cmake-3.x -y

Makefile:57: export PATH=/opt/cmake-3.3.2/bin:$PATH
Makefile:58: 
Makefile:59: *** Fatal。 停止。

我的CMAKE版本

root@root：~/Firmware$ cmake --version
cmake version 3.0.2
CMake suite maintained and supported by Kitware (kitware.com/cmake).

为什么

Answer 1

https://github.com/PX4/Firmware/blob/master/Tools/check_cmake.sh:

if [[ $cmake_ver == *" 2.8"* ]] || [[ $cmake_ver == *" 2.9"* ]] || [[ $cmake_ver == *" 3.0"* ]] || [[ $cmake_ver == *" 3.1"* ]]
then
  exit 1;
fi

该代码明确拒绝cmake版本2.8、2.9、3.0（包括您的3.0.2）、3.1。

您需要将您的cmake升级到至少3.2版本。
