Wrapping C++ Standard library with Cython in ipython

Question

According to the Cython documentation ,I write the following cython code as follows:

In [1]:%load_ext Cython
In [2]: %%cython
         from libcpp.vector c         


        

Answer 1

You need to tell cython that you are compiling C++ and not C, through the special comment

# distutils: language = c++

adding this after the %%cython block will fix your problem.
