error while using make to compile Glibc-2.11.1 for Linux From Scratch
提问by Rohan Bojja
I am building LFS and I am in the part where we need to install Glibc-2.11.1
我正在构建 LFS，我在需要安装 Glibc-2.11.1 的部分
http://www.linuxfromscratch.org/lfs/view/6.6/chapter05/glibc.html

I have successfully configured it but I cant run the make command. Whenever I run the command it runs for a while then stops.
我已成功配置它，但我无法运行 make 命令。每当我运行命令时，它都会运行一段时间然后停止。
I think the following lines show that something I did is incorrect:
我认为以下几行表明我所做的事情是不正确的：

I dont understand where the things went wrong. What I should to correct them?
我不明白哪里出了问题。我应该纠正他们什么？

You need to install gawk.
您需要安装gawk.
sudo apt-get install gawk
The regex on Line 19 was
第 19 行的正则表达式是
/\/[^/]+$/
It is a known issue that mawkdoes not understand unescaped '/' in character classesat least up to version 1.3.3-15 (the one supplied on Ubuntu 11.04 (Natty)). mawkwill think the /inside the bracket terminates the regex, and interpret as \/[^, which is surely a syntax error due to unmatched ].
这是一个已知问题，至少在版本 1.3.3-15（Ubuntu 11.04 (Natty) 上提供的版本）mawk中无法理解字符类中未转义的“/”。mawk会认为/括号内终止正则表达式，并解释为\/[^，这肯定是由于不匹配的语法错误]。
The fix for glibc is trivial: just add a \before the /. But this may also be a dedicate "check" to ensure gawkis used. At least this is still not changed on glibc-2.14…
glibc 的修复很简单：只需\在/. 但这也可能是一个专门的“检查”以确保gawk使用。至少这在 glibc-2.14 上仍然没有改变……
