原因

wheezy是2.13，编译android4.4 需要2.14的，报错如下：

rebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.8-linaro/bin/arm-linux-androideabi-gcc: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found (required by prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.8-linaro/bin/arm-linux-androideabi-gcc)

所以需要升级glibc

出现问题：

出现这个是因为在/etc/apt/sources.list中没有添加testing的源
E: The value 'testing' is invalid for APT::Default-Release as such a release is not available in the sources

升级步骤：

1 添加163的testing的源
#testing
deb http://mirrors.163.com/debian/ testing contrib main non-free
deb-src http://mirrors.163.com/debian/ testing contrib main non-free

2 刷新源
jb@e3v2:~$ sudo apt-get update

3 升级glibc

jb@e3v2:~$ sudo apt-get -t testing install libc6-dev
