help 'GLIBCXX_3.4.20' not found centOS gcc 5+

[Badarosk0]

I performed the rAthena upgrade to the latest version, so I realized that I would need to upgrade my gcc from 4.8 to 5+.

I upgraded to gcc 5.4 and compiled the emulator without any problems.

But from now on he does not care anymore. The map server does not start. I use centos 7.

When I connect the map-server the following message appears and it hangs:

[Warning]: You are running rAthena with root privileges, it is not necessary.
./map-server: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by ./map-server)
./map-server: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by ./map-server)

 

Does anyone know how to solve this problem? 

EDIT:

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 1
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-5 1

Solved.*
