你们的 /lib/tls 里边是什么？

晨想

有这个目录么？里边都有什么文件？或者 /usr/lib/tls 里边有什么？

谢谢。

谢谢。
/lib/tls/libc.so.6 运行结果是什么？
/lib/libc.so.6 这个文件是否存在？

我还想问，如果把这个目录改名了，那系统还能用不？
[color="Red"]不确定的话，别尝试！系统出错我不负责。

ls -l /lib
lrwxrwxrwx  1 root root 5 Aug 31 14:43 /lib -> lib64

如果把/lib/tls/ move掉，系统会报错，系统好像可以运行。以前我升级的时候，系统没有了nptl了，运行的时候，软件会出错的。

谢谢你的回帖。

再问一下：就是说 /lib/ 下还有一个 libc.so.6 文件？

zhllg

我没有/lib/tls
估计可能是这样的
如果用了nptl nptlonly
就没有/lib/tls了

谁同时有/lib/tls/libc.so.6
和/lib/libc.so.6
贴一下/lib/libc.so.6的执行结果
可能里面是LinuxThreads

kohno

我也没有/lib/tls，有/lib/libc.so.6
但我只用了nptl

当你用ldd看一个程序所需库的时候会发现用的是/lib/tls/里面的东西，如果把/tls改名的话他就会用/lib里面的东西，所以将/lib/tls改名系统一样会用只是没有nptl罢了。

看来和我想的是一致的

to kohno:
可不可以贴贴emerge -pv glibc

kohno

# emerge -pv glibc

These are the packages that I would merge, in order:
