Error 6 Solution:

这是因为sdk build tools 25.0.0编译依赖glibc2.14，glibc是linux系统底层api，几乎其它任何运行库都会依赖于glibc。所以如果不是很确定的话，不要轻易更改系统glibc。可以选择升级linux系统，但这显然也不是一个省事儿的办法，那么怎么办呢。

我们可以自己重新编译一个glibc2.14放在其他目录。

Step 1: download 

bash-4.1$ cd /var/lib/jenkins/

bash-4.1$ wget -e "http_proxy=http://proxy:80" http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gz

Step 2: unzip and install

bash-4.1$ tar zxvf glibc-2.14.tar.gz

bash-4.1$ cd glibc-2.14

bash-4.1$ mkdir build

bash-4.1$ cd build

bash-4.1$ ../configure -prefix=/var/lib/jenkins/glibc/glibc-2.14

bash-4.1$ make -j4      //will take 3mins

bash-4.1$ make install
