Ubuntu 12.04 编译Android 4.0.3 的环境配置

本来不喜欢写博客的，在Ubuntu 12.04 下编译了Android 4.0.3发现了一大堆错误，网上找了一堆的更改源码啊，Android.mk的解决方法，虽然可以编译成功，但都有点坑爹的成分，为了不误人子弟就分享出来吧。

根本原因是因为gcc的版本太高，ubuntu 12.04的系统带版本是４.6　的要求严格了，稍微有点不注意就报错。　解决方法就是降级到gcc4.4.

还有就是默认的linux系统调用的头文件路径不是标准的，例如/usr/include/i386-linux-gnu/sys

啥都别废话了，　先装下面的一堆依赖库再说

sudo apt-get -y install lib64quadmath0 lib64gomp1 lib64gcc1 libc6-amd64　libc6-dev-amd64 gcc-multilib gcc-4.6-multilib libc-bin libc-dev-bin　libc6-dev libc6 build-essential linux-headers-generic linux-libc-dev　libmpfr-dev libmpfr libgmp-dev libgmp uboot-mkimage u-boot-tools　libglib2.0-dev libpcre3-dev git-man liberror-perl git git-core tree　gperf fakeroot dkms libgsoap1　 libpthread-stubs0-dev libpthread-stubs0　libx11-dev subversion vim g++ bison openjdk zlib1g-dev flex libncurses5-dev　gcc-4.4 g++-4.4 g++-4.4-multilib

装完后，开始降级gcc , 放心，这不会影响到系统的情绪，就改个链接而已，不喜欢的话改回来就好

cd /usr/bin
sudo mv gcc gcc.bk
sudo ln -s gcc-4.4 gcc
sudo mv g++ g++.bk
sudo ln -s g++-4.4 g++

好了～～～完成，可以完美编译了。

以上方法可以解决下面的一堆所谓坑爹的问题，哥也傻过了，你们就别傻改代码了啦
