在Ubuntu建立arm-linux-gcc交叉編譯環境

Step1:先下載arm-linux-gcc-4.3.2.tgz
       
Step2:確認安裝標準C的開發環境：sudo apt-get install build-essential libncurses5-dev


Step3:在終端下到arm-linux-gcc-4.3.2.tgz存放目錄


step4:下指令    sudo tar -zxvf arm-linux-gcc-4.3.2.tgz -C /（注意大寫C後留一個空格，這樣會自動解壓縮缩到/usr/local/4.3.2目錄下）


step5:檢查環境變量    echo $PATH


step6:修改環境變量    sudo gedit /etc/environment


step7:把原來的    PATH="/usr/local/sbin:/usr/local/bin:/usr /sbin:/usr/bin:/sbin:/bin: /usr/games“   修改成                                    PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin: /sbin:/bin:/usr/game/usr/local/arm/4.3.2/bin"


step8:然後登出 在登入就修改完成


step9:下指令    arm-linux-gcc -v
