in the CMakeLists.txt fil

Answer 1

Most of you getting that error "cc1plus: error: unrecognized command line option -std=gnu++0x" while installing nodejs extension which requires C++ compilation with node-gyp. So how to solve this error so here is the solution. Basically you get these errors because of Nodejs different version as many node libraries requires C or C++ compilation while installing. So Nodejs older version uses python 2.7 with gcc compiler less than version 4.2 but Nodejs newer version uses gcc44 compiler that's why you get above error while installing any nodejs library.

So you need to degrade your nodejs and node-gyp version and specify the python version if you have multiple python versions installed on your system and then you will not get above error anymore.
