我想将我的一个c ++类作为Python模块提供.该类在头文件中声明,Foo.h并以.cpp实现Foo.cpp.(g ++ - 4.5,Ubuntu x86_64).这是一个非常简单的课程:
Foo.cpp:
Foo::Foo() : alfa(1.0), beta(1)
{
}
Foo::~Foo()
{
}

Foo.h:
class Foo
{
public:
Foo()
Foo(const Foo& orig);
~Foo();
double alfa;
int beta;
};

我创建了一个setup.py如Cython教程中所示:
setup.py
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
setup(
name = 'MyDemo',
ext_modules=[
Extension("Foo"
sources=["Foo.pyx"],
include_dirs=[".","../eigen/"],
language="c++"),
],
cmdclass = {'build_ext': build_ext},
)

并按照cython教程的指示编写我的Foo.pyxcython模块:
Foo.pyx
cdef extern from "Foo.h":
ctypedef struct c_Foo "Foo": …Run Code Online (Sandbox Code Playgroud) 我正在尝试使用icc编译器在Ubuntu 14.04上从源代码构建cython,因为我的python是用Intel icc编译器编译的.
当我尝试使用pip3安装cython安装cython然后运行cython时出现以下错误

如何使用icc编译器从源代码安装cython?
我试过这个并没有用
从cython目录(从github下载)
python3.4 setup.py CC = icc
我收到以下消息 -
