Configure the arm-Linux-gcc

Configure arm-Linux-GCC on the basis of the installation on the Linux platform to make it work normally.

I. Preparations before installation

1. Download and install arm-Linux-gcc

The version of the arm-linux-gcc-4.2.1 IN THE RELEASE.

The following is the download link officially provided by arm: http://www.codesourcery.com/gnu_toolchains/arm/download.html. After that, select host32 GNU/Linux and click Download. But the prefix is arm-2010.09-51-arm-none-eabi-i686-pc-linux-gnu instead of arm-Linux -...

Download arm-linux-gcc4.4.3from the official website http://www.arm9.net/download.asp.

2. Delete the old version installed before, and run

[Root @ localhost ~] # Rm-RF/opt/ARM

3, extract the new version of the arm-linux-gcc-4.4.3 (note, if we add-C, it will automatically decompress to the/usr/local/ARM/directory ), however, the friendly arm is unzipped to the/usr/local/ARM/directory according to the following methods, this is because the friendly arm changes the/usr/local/ARM/directory to/opt/friendlyarm/toolschain/unless it is being modified.

[Root @ localhost ~] # Tar-ivxzf/smbroot/arm-linux-gcc-4.4.3.tar.gz-C/

4. modify the configuration file and add arm-Linux-GCC to the environment variable, because the command of arm-Linux-GCC is under/usr/local/ARM/4.4.3/bin, the purpose is to bind global variables so that the command can be executed in any directory.

Open the setting file

[Root @ localhost opt] # vi/etc/profile

In

# Path manipulation
If ["$ EUID" = "0"]; then
Pathmunge/sbin
Pathmunge/usr/sbin
Pathmunge/usr/local/sbin
Pathmunge/usr/local/ARM/4.4.3/bin
Fi
Or add

Export Path = $ path:/usr/local/ARM/4.4.3/bin

Save and exit

5. Make the new environment variable effective immediately without restarting the computer

[Root @ localhost opt] # source/etc/profile

[Root @ localhost opt] #

6. Check whether the path is added to the path:

[Root @ localhost opt] # echo $ path

/Usr/local/ARM/4.4.3/bin is displayed, indicating that the path of the cross compiler has been added to path. So far, the cross-compilation environment installation is complete.

7. test whether the installation is successful.

First, run the find command to query the location of arm-Linux-GCC.

[Root @ localhost ~] # Find/-name arm-Linux-gcc

/Opt/ARM/toolschain/4.4.3/bin/ARM-Linux-gcc
[Root @ localhost ~] #

We can see that the location of arm-Linux-GCC is consistent with the path set in environment variables.

Next, query the arm-Linux-GCC version.

[Root @ localhost bin] # arm-Linux-gcc-V
Using built-in specs.
