'versão' GLIBCXX_3.4.20 'não encontrado' no aplicativo compilado

Question

Depois de criar meu aplicativo usando vamp-plugins :

kokos@kokos-Latitude-E6230:~/repo/pitchtracker/pitchtracker$ ./vamp-simple-host -l

O seguinte erro ocorre:

./vamp-simple-host: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version 'GLIBCXX_3.4.20' not found (required by ./vamp-simple-host)
./vamp-simple-host: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version 'GLIBCXX_3.4.21' not found (required by ./vamp-simple-host)

Eu tentei seguir:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test

sudo apt-get update e também upgrade e dist-upgrade

export LD_LIBRARY_PATH=${prefix}/lib:$LD_LIBRARY_PATH

E isso:

mv -vf libstdc++.so.6 libstdc++.so.6.old
ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 ./libstdc++.so.6

Causou um erro de sistema SÉRIO

Saída da política do apt-cache libstdc ++ 6:

libstdc++6:
  Zainstalowana: 7.1.0-5ubuntu2~14.04

Eu obtive plugins para vampiros compilando da fonte que baixei do site oficial deles:

./configure
make 
sudo make install
