准備玩玩ARM板子了，今天嘗試著建立一下編譯環境。
U-BOOT的ELDK已經發到5.0版本了。
而且，相較以前的ELDK版本，這個版本的安裝路徑不能在重定位了，規定死了要安裝在 /opt/eldk-5.0/ 目錄下，所以我預先建立了/opt/eldk-5.0/路徑。
root@xUbuntu-laptop:/opt# ls
eldk-5.0
root@xubuntu-laptop:/opt#
至於，我選擇的是針對 普通ARM的 armv5te架構的版本，下載的文件則有，見下面紅色字體的文件
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 3 root root 4096 2011-10-06 12:24 targets

-rw-r--r-- 1 root root 71 2011-10-06 12:26 target.conf
root@xubuntu-laptop:/home/eldk-download#
安裝很簡單，如下，藍色部分為提示信息
root@xubuntu-laptop:/home/eldk-download# ls
install.sh targets
root@xubuntu-laptop:/home/eldk-download# ./install.sh -i qte armv5te

運行完畢，則進入/opt/eldk-5.0 目錄
