error This file requires compiler and library support

[贾已]

When I run "install" command in octave, it tell me :

/usr/include/c++/5/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

My system:

ubuntu 16.4
gcc 5.5.0 ( support to c++11 )

Anyone else meet this problem?
