error: command 'c++' failed with exit stat

So I am trying to install Pyv8 by following instruction from https://andrewwilkinson.wordpress.com/2012/01/23/integrating-python-and-javascript-with-pyv8/


    sudo aptitude install scons libboost-python-dev
    svn checkout http://v8.googlecode.com/svn/trunk/ v8
    svn checkout http://pyv8.googlecode.com/svn/trunk/ pyv8
    cd v8
    export PyV8=`pwd`
    cd ../pyv8
    python setup.py build
    sudo python setup.py install

Error comes when running second last command about building the setup.

回答1:

It is because the version of gcc and g++ is too low for me, as I downgrade it when i install cuda sometime. Just follow the following commands:

$ cd /usr/bin 
$  rm gcc
$ ln -s gcc-5 gcc  
$ rm g++
$ ln -s g++-5 g++

Done.

I followed the instructions from this link - http://ubuntuforums.org/showthread.php?t=1480282#post_11247864 and installed the libboost_thread package which solved the problem. Thank you https://stackoverflow.com/users/440558/joachim-pileborg
