如何在ubuntu中搭建交叉编译环境

1.安装交叉编译环境 sudo apt-get install gcc g++ libcc1 libg++ make
gdb

2.安装交叉编译器 ftp://ftp.arm.linux.org.uk/pub/armlinux/toolchain/ 下载
cross -3.2.tar.bz2或者懒得去找干脆

wget ftp://ftp.arm.linux.org.uk/pub/armlinux/toolchain/ cross
-3.2.tar.bz2

解压

sudo tar jxvf /home/zhaifang/cross -3.2.tar.bz2

sudo mv /home/zhaifang/usr/local/arm /usr/local

3.交叉编译器加入路径  sudo vi
/etc/bash.bashrc后面加入 

if [ -d /usr/local/arm ] ; then

PATH=/usr/local/arm/bin:"${PATH}"

fi
4.使环境生效 #source /etc/profile

5.检查 echo $PATH 出现/usr/local/arm/bin说明成功了

6.测试 arm-linux-gcc -v
