skypeforlinux-8.9.0.1-1.x86_64 需要 libstdc++.so.6(GLIBCXX_3.4.20)(64bit)

Question

我的环境：

$ cat /etc/redhat-release 
CentOS Linux release 7.4.1708 (Core) 
$ uname -a
Linux X 3.10.0-693.5.2.el7.x86_64 #1 SMP Fri Oct 20 20:32:50 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
$ rpm -q glibc
glibc-2.17-196.el7.x86_64
glibc-2.17-196.el7.i686
$ 

我正在尝试关注下载 Skype | 免费电话 | 聊天应用程序：

$ sudo rpm -ivh https://go.skype.com/skypeforlinux-64.rpm
Retrieving https://go.skype.com/skypeforlinux-64.rpm
error: Failed dependencies:
    libstdc++.so.6(GLIBCXX_3.4.20)(64bit) is needed by skypeforlinux-8.9.0.1-1.x86_64
$ 

难道我做错了什么？还是站在微软一边？

Answer 1

看来您正在运行 Centos 7。strings /usr/lib/libstdc++.so.6 | grep GLIBCXX在 Centos 7 中发出命令时，它显示以下输出：

GLIBCXX_3.4
_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3
GLIBCXX_3.4.4
GLIBCXX_3.4.5
GLIBCXX_3.4.6
GLIBCXX_3.4.7
GLIBCXX_3.4.8
GLIBCXX_3.4.9
GLIBCXX_3.4.10
GLIBCXX_3.4.11
GLIBCXX_3.4.12
GLIBCXX_3.4.13
GLIBCXX_3.4.14
GLIBCXX_3.4.15
GLIBCXX_3.4.16
GLIBCXX_3.4.17
GLIBCXX_3.4.18
GLIBCXX_3.4.19
GLIBCXX_DEBUG_MESSAGE_LENGTH

这意味着目前 Centos 不支持最新版本的 Skype (v8.9) 所需的 glibc (即 GLIBCXX_3.4.20) 版本。

如果现在希望在 Centos 中安装 Skype，您可以查看托管预编译版本 Skype（可能是旧版本）的 nux 存储库。或者，您始终可以从源代码构建最新的 glibc，然后尝试安装 Skype。

...不是最好的方法，但是可以使用--nodeps，如下所示：

$ sudo rpm -ivh https://go.skype.com/skypeforlinux-64.rpm --nodeps

$ echo $?
0

另一种方法是降级到旧版本的 Skype：

下一步仅适用于您使用--nodeps选项的情况，否则跳至下一步：

$ sudo yum remove skypeforlinux
