当我在 GNU 构建之后尝试使用开源时，发生了一件奇怪的事情，如下：
- ./configure ./make ./make install 中没有出现错误
当我尝试使用它时，此管理脚本中有一些没有初始化值的变量。该脚本称为“ionadmin”，这些 NULL 变量之一是，例如“NO_GLOB_SUBST”。
我在文档中找不到这个名称“NO_GLOB_SUBST”。否则，我无法使用以下命令在根路径中找到赋值操作：
查找 ~/ -type f |xargs grep 'NO_GLOB_SUBST'
还有脚本：
#!/bin/bash
# ionadmin - temporary wrapper script for .libs/ionadmin
# Generated by libtool (GNU libtool) 2.4.2 Debian-2.4.2-1.7ubuntu1
#
# The ionadmin program cannot be directly executed until all the libtool
# libraries that it depends on are installed.
#
# This wrapper script should never be moved out of the build directory.
# If it is, it will not operate correctly.
# Sed substitution that helps us do robust quoting. It backslashifies
# metacharacters that are still active within double-quoted strings.

所以，这是我的问题： 该脚本的作者在什么情况下使用这些未初始化的变量？或者，我忽略了一些错误？我还发布了另一个问题：点击
