libstdc++.so.6(glibcxx_3.4.21)

[laurczt]

Hello,
As the title says i need to install libstdc++.so.6 glibcxx_3.4.21 (at the moment i have libstdc++.so.6 glibcxx_3.4.19) on my centos 7 server. I've searched around the web but i can't find a solution. Maybe you could help me fixing this issue.

Thanks!

No, you don't. It's the other way round, you need to get hold of the application you want to run that's actually built to run on CentOS 7. You cannot shoehorn newer libstdc++/glibc into an older distribution that's entirely built around an older copy of it. You will break lots of stuff and end up reinstalling.

What application are you trying to install that wants this?

Rust dedicated server. And i get this error when i start the application (before last night update it was working and now not anymore).
Error:

Code: Select all

Couldn't open /home/server/rust_test/RustDedicated_Data/Plugins/x86_64/libRakNet.so, error: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /home/server/rust_test/RustDedicated_Data/Plugins/x86_64/libRakNet.so)

And this is the result i get when i do: strings /usr/lib64/libstdc++.so.6 | grep GLIBC

You'll need to complain to the people you got that from. It will never work on CentOS and if you try, you will almost certainly break your system.

Thanks. What about install the newest version of centos ? U think it will fix the problem ?

[TrevorH]

CentOS 7 is the newest version.

I fixed the issue thanks for your support.
For those who want to know how i fix it. I replaced the libRakNet.so with the one before update. If you don't have it anymore you can download it from here (OneDrive Link). Hope this will help others too. Thanks TrevorH for all help he gave me, i want to mention that he respond very fast and i appreciate it!
