本文提供了一套在Ubuntu操作系统下进行跨平台编译的详细步骤，包括安装交叉编译器、修改Makefile文件以适配特定目标平台、以及利用SSH和SSHFS进行远程代码调试的方法。通过在本地PC上进行编译和调试，再通过简单复制命令将编译结果传输到目标设备，实现高效、便捷的开发流程。

The fact is quite obviously that the calculation ability of the CPU in our UAV is not powerfull enough to compile source files, even if the source file is not large. So I think cross-compilation is a better choice for our developing task in most time. Here I will share some tips for such a environment setting steps in a machine with Ubuntu OS.

1. install cross compiler
   sudo apt-get install gcc-arm-linux-gnueabi

2. modify your makefile
    you can redefine your gcc, for example:
    the original command in your Makefile is:
        gcc test.c -o test1
    you can modify with:
        GCC=arm-linux-gnueabi-gcc
        GCC test.c -o test1
    It's clear that you can debug your codes in PC just with GCC=gcc.

3. enjoy the process of speed: ^_^
    here, I wana give a device for developing. For my case,
   a> use ssh to debug applications on raspberry board
   b> use sshfs to make a link to files on raspberry board
   c> use cross-compilation environment to compile source files

    first I cross-compile source files; then, I copy the compile result to raspberry just with a simple command 'cp', because of sshfs; and finally, use ssh to call the application to debug my codes.

    I do everything in my PC screen within only 2 windows.Everything become more easy, right? I hope these tips will do help to you. Good Luck~
