Answer 1

Se você encontrou o problema com

configure: c++11 mode is requested but the current compiler does not support it.

durante a execução de ./configure linux em um 64bit ubuntu 15.10, isso pode ser resolvido instalando / atualizando seus pacotes gcc e g++ :

sudo apt-get update
sudo apt-get install gcc g++

e especificando sua arquitetura no comando configure:

./configure linuxx8664gcc
