Ubuntu 编译android GCC降级

操作方法：

1. 查看gcc版本和g++版本

xumingtao@huaserver1:/usr/bin$ ls -l gcc*
lrwxrwxrwx 1 root root
7 Aug 30 19:26 gcc -> gcc-4.6
-rwxr-xr-x 1 root root 353216 Apr 16 07:37 gcc-4.6

xumingtao@huaserver1:/usr/bin$ ls -l g++*
lrwxrwxrwx 1 root root

-rwxr-xr-x 1 root root 357312 Apr 16 07:36 g++-4.6
2. 安装gcc和g++ 4.4版本

sudo apt-get install gcc-4.4 g++-4.4 g++-4.4-multilib

3. 修改gcc链接

sudo mv gcc gcc.bak
sudo ln -s gcc-4.4 gcc

xumingtao@huaserver1:/usr/bin$ ls -l gcc*
lrwxrwxrwx 1 root root
7 Sep 6 10:43 gcc ->
gcc-4.4
-rwxr-xr-x 1 root root 259232 Apr 16 14:20 gcc-4.4
-rwxr-xr-x 1 root root 353216 Apr 16 07:37 gcc-4.6
lrwxrwxrwx 1 root root
7 Aug 30 19:26 gcc.bak -> gcc-4.6
4. 修改g++链接

sudo mv g++ g++.bak
sudo ln -s g++-4.4 g++

xumingtao@huaserver1:/usr/bin$ ls -l g++*
lrwxrwxrwx 1 root root
7 Sep 6 10:45 g++ ->
g++-4.4
-rwxr-xr-x 1 root root 263328 Apr 16 14:18 g++-4.4

lrwxrwxrwx 1 root root
7 Mar 14 04:05 g++.bak -> g++-4.6
