关于glibc:centos65-安装-glibc214遇到的问题

1、配置装置门路../configure –prefix=/usr/local/glibc-2.14 时报错

checking for gcc... no
checking for cc... no
checking for cl.exe... no
configure: error: in `/home/shenpeipei/glibc-2.14/build':
configure: error: no acceptable C compiler found in $PATH

—– 起因：没有 c 编译器
—– 解决办法：装置 gcc

yum install gcc

2、编辑装置 make && make install 时出错

Can't open configuration file/opt/glibc-2.14/etc/ld.so.conf: No such file or directory

—– 解决办法：

touch usr/local/glibc-2.14/etc/ld.so.conf
或者 find / -name "ld.so.conf" 能够发现 /etc/ld.so.conf 这个文件，而后复制过去就能够了 cp /etc/ld.so.conf /usr/local/glibc-2.14/etc/

3、删除 libc.so.6 后 ln、ls 等命令都不可用
—– 解决办法：

export LD_PRELOAD=/lib64/libc-2.12.so 执行完 ln -s /lib64/libc-2.14.so libc.so.6 后再改为 LD_PRELOAD=/lib64/libc-2.14.so 
或者间接 export LD_PRELOAD=/lib64/libc-2.14.so 再执行 ln -s /lib64/libc-2.14.so libc.so.6

4、装置完 glibc-2.14 后发现 locale 会有问题
—– 景象一：断开从新登录会有 warning

-bash: warning: setlocale: LC_CTYPE: cannot change locale (en_US.UTF-8): No such file or directory
-bash: warning: setlocale: LC_COLLATE: cannot change locale (en_US.UTF-8): No such file or directory
-bash: warning: setlocale: LC_MESSAGES: cannot change locale (en_US.UTF-8): No such file or directory
-bash: warning: setlocale: LC_NUMERIC: cannot change locale (en_US.UTF-8): No such file or directory
-bash: warning: setlocale: LC_TIME: cannot change locale (en_US.UTF-8): No such file or directory

—– 景象二：输出 locale, 会有报错

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

—– 起因：就是更新了 glibc-2.14 导致系统去 glibc-2.14 目录去找 locale 文件，后果没找到导致的
—– 解决办法：

mkdir /usr/local/glibc-2.14/lib/locale
cp /usr/lib/locale/locale-archive /usr/local/glibc-2.14/lib/locale/locale-archive
