如何检查Linux上的glibc版本

Posted 2023-04-02

参考技术A

1、首先连接上Linux主机，如图所示，使Linux主机处于一个命令状态。

2、然后看到是处于命令行状态，如图所示，接下需要输入rpm -qi glibc的命令。

3、最后，输入之后，回车键确定，进入glibc的详细信息，其中“Version”后面显示的就是版本了，这样操作即可解决问题。

markdown 如何检查支持的glibc版本

# Check the supported GLIB symbols
You can check the gcc version and other useful information running directly the libc.so library (yes, you can run the library from console):
You would see something like this:

```
user@host-machine:~$ /lib/x86_64-linux-gnu/libc.so.6
GNU C Library (Ubuntu GLIBC 2.27-3ubuntu1) stable release version 2.27.
Copyright (C) 2018 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.

libc ABIs: UNIQUE IFUNC
For bug reporting instructions, please see:
<https://bugs.launchpad.net/ubuntu/+source/glibc/+bugs>.

```

To check the c++ versions:

```
$ objdump -x /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX_
$ objdump -x /lib/x86_64-linux-gnu/libc.so.6 | grep GLIBC_
```

To check the GLIBC versions

```
& ldd --version
```

The libc.so file is stored in (ubuntu): 

```
/lib/x86_64-linux-gnu/libc.so.6
```
