在ipython中用Cython包装C ++标准库 [英] Wrapping C++ Standard library with Cython in ipython

问题描述

根据Cython文档，我编写以下cython代码，如下所示：

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

In [1]:%load_ext Cython
In [2]: %%cython
         from libcpp.vector cimport vector
​         cdef vector[int] *vec_int = new vector[int](10)

编译后，ipython产生以下错误：

After compiling,the ipython generated the following error:

Error compiling Cython file:
------------------------------------------------------------ 
... 
from libcpp.vector cimport vector 
cdef vector[int] *vec_int = new vector[int](10) 
                               ^ 
------------------------------------------------------------
/Users/m/.ipython/cython/_cython_magic_a72abb419ccf1b31db9a1851b522a4bf.pyx:3:32: Operation only allowed in c++

我的代码有什么问题？

推荐答案

您需要告诉 cython 您正在编译 C ++ 而不是 C ，通过特殊注释

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

# distutils: language = c++

将此添加到 %% cython 之后块将解决您的问题。

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