Are two different libstdc++.so.6 possible on the same system?

Question

linux

The latest gcc7, g++7 and libstdc++.so.6 (GXX 24) are installed out of the box. On this system, you need to compile an application that should work on older systems with older libstdc++.so.6 (GXX 19). When you try to run this application on those systems, it accordingly gives an error that GXX 21 was not found. Installed gcc5 and g++5 next to gcc7, compiled the application through g++5 - the same error when starting. Most likely it's the newer libstdc++ library. When trying to put an older libstdc++5 next to a newer libstdc++7, a conflict appears. How to be? Compile on each platform separately?

Answer 1

Did you install it by batch or manually? If it's a package, conflict is inevitable - after all, yum relies on libstdc++ being the only one on the system. Most likely, you will have to install it manually and at the same time very carefully distribute them into folders - so that the installer does not accidentally crash a newer one.
And to work with it, you may have to specify additional parameters, or even file configure.

Answer 2

Not sure what OS you have. However, for gents, different versions of the same software are not a problem.
