Hello, I'm trying to install a game server for a game called Cube on my RedHat 7.3 server. However, when I try to run the binary i get:

./linux_server: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

However, when I ls /usr/lib/ i find the following files among them.

libstdc++-libc6.1-1.so.2
libstdc++-libc6.2-2.a.3
libstdc++-libc6.2-2.so.3
libstdc++.so.2.7.2
libstdc++.so.2.7.2.8
libstdc++.so.2.8
libstdc++.so.2.8.0
libstdc++.so.2.9
libstdc++.so.2.9.dummy
libstdc++.so.5

so what's the output of:
It shows you where it tries to find libraries... Usually, you have issues like yours when libraries are stored in /usr/local/lib or unusual lib directories...
What you can try to solve this is to set LD_LIBRARY_PATH variable to:
Oliv'

Don't worry about it, I've fixed it.
