./MCServer: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by ./MCServer)
How I can instalL GLIBCXX 3.4.15
Try to compile MCServer yourself.
Bearbin build server is using Debian 7/8 with a more recent glib version, so it doesn't work with an older one.
Yeah, compiling yourself is the right thing to do, or upgrade your OS version.
