我正在构buildLFS，而我正处于需要安装Glibc-2.11.1的部分
http://www.linuxfromscratch.org/lfs/view/6.6/chapter05/glibc.html
我已经成功configuration它，但我不能运行make命令。 每当我运行命令它运行一段时间然后停止。
我认为以下几行显示我做的事情是不正确的：

你需要安装gawk 。
sudo apt-get install gawk
第19行的正则表达式是
/\/[^/]+$/
这是一个已知的问题， mawk不能理解字符类中未转义的“/” ，至少在版本1.3.3-15（在Ubuntu 11.04（Natty）上提供的那个）。 mawk会认为括号内的/终止了正则表达式，并解释为\/[^ ，这肯定是由于不匹配导致的语法错误] 。
glibc的修正是微不足道的：在/之前加一个\ 。 但这也可能是一个专门的“检查”， 以确保使用gawk 。 至少这个在glibc-2.14上还是没变
