GNU交叉工具链(arm-linux-gcc 3.4.4)

1 Linux下工作用户及环境

1.1软件环境

Linux ubuntu 6.06 LTS

Kernel version 2.6.15-23-686

gcc version 4.0.3 (Ubuntu 4.0.3-1ubuntu5)

GNU Make 3.81

msgfmt (GNU gettext-tools) 0.14.5

makeinfo (GNU texinfo) 4.8

GNU M4 1.4.4

flex 2.5.31

GNU Awk 3.1.5

perl, v5.8.7

GNU sed version 4.1.4

gettext (GNU gettext-runtime) 0.14.5

autoconf (GNU Autoconf) 2.59

automake (GNU automake) 1.4-p6

1.2 编译相关配置

1. 添加工作用户(在root用户下)

root@ubuntu:~# useradd -G root -g root -d/home/arm arm

root@ubuntu:~# mkdir -p /home/arm

root@ubuntu:~# chown -R arm /home/arm

root@ubuntu:~# chmod -R 775 /home/arm

2. 建立工作目录(用arm用户登陆)

arm@ubuntu:~$ mkdir dev_home

arm@ubuntu:~$ cd dev_home

arm@ubuntu:~/dev_home$ mkdir btools kernel

3. 登陆时启动环境变量(用root用户登陆)

root@ubuntu:~# vi ~/.bashrc

在.bashrc最后加上

export PATH=/usr/local/arm/3.4.4/bin:$PATH

arm@ubuntu:~/dev_home$

重新登陆arm用户,环境变量生效

arm@ubuntu:~$ su arm

2. 设置环境变量,准备源码及相关补丁

2.1 设置环境变量

arm@ubuntu:~$ vi ~/.bashrc

export PREFIX=/usr/local/arm/3.4.4

export TARGET=arm-linux

export SYSROOT=${PREFIX}/sysroot

export ARCH=arm

export CROSS_COMPILE=${TARGET}-

export PATH=${PREFIX}/bin:$PATH

export SRC=/home/arm/dev_home/btools/tchain3.4.4

注意: 如果你已经安装过arm-linux-gcc,并且已经加入了环境变量中,将其从环境中去掉保证root用户和arm用户环境中没有arm-linux-gcc

2.2 准备源码包

2.2.1 binutils

名称：binutils-2.16.tar.gz

tar.gz

下载地址：

2.2.2 gcc

名称: gcc-3.4.4.tar.bz2

下载地址:

2.2.3 glibc

名称:   glibc-2.3.5.tar.gz

           glibc-linuxthreads-2.3.5.tar.gz

下载地址:  

                 

2.2.4 linux kernel

名称:   linux-2.6.14.1.tar.bz2

下载地址:

2.2.5 gdb

名称: gdb-6.4.tar.gz

下载地址:

2.3 准备补丁

2.3.1 ioperm.c.diff

作用: 打修正ioperm()函数

下载地址:

2.3.2 flow.c.diff

作用: 修改gcc一处bug

下载地址:

2.3.3 t-linux.diff

作用: 该补丁用于产生crti.o和crtn.o文件.

下载地址:

2.4 编译GNU binutils

重新以arm用户登陆,让新设置得环境变量起作用
