x210 installation and validation cross compilation tools chain

I have here is the direct use of the board s5pv210, the method according to Zhu large lecture hall, according to the official installation package to install cross compiler tool chain (also a useful source installation of this high force grid, temporarily refrain)

arm-2009q3.tar.bz2

This package mv to the / usr / local / ARM new directory under the directory

tar -jxvf /usr/local/arm/

After decompression, it will create a new directory in the current directory arm-2009q3

Into the inside of the bin directory, ls cross compiler can see all the tools in the chain as follows

arm-none-linux-gnueabi- addr2line for the call stack when the program crashes positioning information when debugging #

-none-Linux-ARM-gnueabi gprof # very useful debugging tool

-none-Linux-ARM gnueabi-Ar # static library generation tools

-none-Linux-ARM gnueabi-LD # linker

arm-none-linux-gnueabi-objdump # disassemble

arm-none-linux-gnueabi-cpp #C preprocessor

arm-none-linux-gnueabi-gdb # very useful debugging tool

-none-Linux-ARM-gnueabi AS # This is the doing of ?

-none-Linux-ARM-nm gnueabi # symbol View

none-Linux--ARM-the objcopy # gnueabi the objcopy is used to copy the contents of a target file to another file,

可以使用不同于源文件的格式来输出目的文件，即可以进行格式转换(.elf转.bin)

arm-none-linux-gnueabi-c++ #这个C++是干啥的？

arm-none-linux-gnueabi-c++filt

arm-none-linux-gnueabi-ranlib

arm-none-linux-gnueabi-g++

arm-none-linux-gnueabi-readelf

arm-none-linux-gnueabi-gcc

arm-none-linux-gnueabi-size

arm-none-linux-gnueabi-gcc-4.4.1

arm-none-linux-gnueabi-sprite

arm-none-linux-gnueabi-gcov

arm-none-linux-gnueabi-strings

arm-none-linux-gnueabi-strip

arm-none-linux-gnueabi-gdbtui

如何验证一下是否安装成功呢，那就去执行

./arm-none-linux-gnueabi-gcc -v

发现打印出来一堆消息，最后是

gcc version 4.4.1 (Sourcery G++ Lite 2009q3-67) 这就说明我们安装成功了

然后我们来把这个目录添加到系统的环境变量

vi ~/.bashrc

然后在尾部添加

export PATH=$PATH:/usr/local/arm/arm-2009q3/bin

注意这个需要退出当前console再进入的时候才会有效

然后是为这些工具创建符号链接

有一个脚本，直接拷过去/usr/local/arm/arm-2009q3/bin执行就行

=========================================================

其实上述步骤完全可以用一个脚本来实现，为了以后搭建环境时省一些时间，我这里写了一个一键安装脚本envsetup.sh

#!/bin/bash

    cd $DIR
    unset DIR

sed -i '$a export PATH=$PATH:/usr/local/arm/arm-2009q3/bin' ~/.bashrc

使用的时候把压缩包和这个脚本放在同一个目录下，然后执行 . envsetup.sh即可
