[error]LD_LIBRARY_PATH shouldn't contain the current directory

编译libc执行configure时遇到如下问题:

LD_LIBRARY_PATH shouldn't contain the current directory

执行指令：echo $LD_LIBRARY_PATH，发现并没有指定当前目录。

打开configure文件，查找LD_LIBRARY_PATH，找到如下内容：

# Test if LD_LIBRARY_PATH contains the notation for the current directory

# since this would lead to problems installing/building glibc.

# LD_LIBRARY_PATH contains the current directory if one of the following

# is true:

# - one of the terminals (":" and ";") is the first or last sign

# - two terminals occur directly after each other

# - the path contains an element with a dot in it

因为在环境变量的最前和最后均有一个“:”，程序将此分隔符解释为当前目录了。

解决方法：

执行指令：vi ~/.bash_profile

将LD_LIBRARY_PATH环境变量的形如和末尾的“:”去掉，保存。

执行指令：source ~/.bash_profile
