Replace the ARM-LINUX-GCC 4.3.2 compiler

First create a temp directory: [email protected]:/home/work/tools$ mkdir tmp

Unzip to root directory: [email protected]:/home/work/tools$ sudo tar xjf arm-linux-gcc-4.3.2.tar.bz2-c/(cross-compilation tool must be extracted to the root directory, otherwise there will be compile error, such as ）

View environment variables: [email protected]:/work/tools$ echo $PATH
Setting Environment variables: vi/etc/profile

Add it on the inside:

Export Path=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/arm/4.3.2/bin

Bring it into effect: source/etc/profile

(Note: Each time you restart the terminal path recovery, to execute this command)

View Environment variables: Echo$path

It's path=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/arm/4.3.2/bin.

That's right.
