准备玩玩ARM板子了，今天尝试着建立一下编译环境。

U-BOOT的ELDK已经发到5.0版本了。

而且，相较以前的ELDK版本，这个版本的安装路径不能在重定位了，规定死了要安装在 /opt/eldk-5.0/ 目录下，所以我预先建立了/opt/eldk-5.0/路径。

至于，我选择的是针对 普通ARM的 armv5te架构的版本，下载的文件则有，见下面红色字体的文件

root@xubuntu-laptop:/home/eldk-download# ls -al
total 20
drwxr-xr-x 3 root root 4096 2011-10-06 12:25 .
drwxr-xr-x 13 root root 4096 2011-10-14 22:59 ..
-rwxrwxrwx 1 root root 4909 2011-10-06 12:25 install.sh
drwxr-xr-x 3 root root 4096 2011-10-06 12:24 targets
root@xubuntu-laptop:/home/eldk-download# ls -al targets/armv5te/
total 499692
drwxr-xr-x 2 root root 4096 2011-10-07 17:36 .
drwxr-xr-x 3 root root 4096 2011-10-06 12:24 ..
-rw-r--r-- 1 root root 151669927 2011-10-06 13:31 eldk-eglibc-i686-arm-toolchain-qte-5.0.tar.bz2
-rw------- 1 root root 359995091 2011-10-07 17:42 poky-image-qte-sdk-armv5te.tar.gz
-rw-r--r-- 1 root root 71 2011-10-06 12:26 target.conf
root@xubuntu-laptop:/home/eldk-download#

安装很简单，如下，蓝色部分为提示信息

root@xubuntu-laptop:/home/eldk-download# ls
install.sh targets
root@xubuntu-laptop:/home/eldk-download# ./install.sh -i qte armv5te

运行完毕，则进入/opt/eldk-5.0 目录

root@xubuntu-laptop:/home/eldk-download# cd /opt/eldk-5.0/
root@xubuntu-laptop:/opt/eldk-5.0# ls -al
total 12

利用 source 命令，更新eldk相关的环境变量

root@xubuntu-laptop:/opt/eldk-5.0# cd armv5te/
root@xubuntu-laptop:/opt/eldk-5.0/armv5te# ls
environment-setup-armv5te-linux-gnueabi sysroots
rootfs version-armv5te-linux-gnueabi
site-config-armv5te-linux-gnueabi
root@xubuntu-laptop:/opt/eldk-5.0/armv5te# source environment-setup-armv5te-linux-gnueabi

利用export显示环境变量
