Question

我尝试在python中运行v8（google javascript引擎）。尝试执行此示例https://developers.google.com/v8/get_started：

setup.py

from distutils.core import setup
from distutils.extension import Extension
from Cython.Build import cythonize
from Cython.Distutils import build_ext

import os
from distutils.sysconfig import get_config_vars

(opt,) = get_config_vars('OPT')
os.environ['OPT'] = " ".join(
    flag for flag in opt.split() if flag != '-Wstrict-prototypes'
)

setup(
    name = 'helloworld',
    ext_modules = cythonize(
        Extension(
            "helloworld",
            ["helloworld.pyx"],
            language = "c++",
            libraries = ["v8"],
            library_dirs = ["v8"],
            include_dirs = ["v8/include"],
            extra_compile_args = ["-std=c++11"],
            extra_link_args = ["-std=c++11"],
            cmdclass = {'build_ext': build_ext}
        )
    )
)

helloworld.pyx

from libcpp cimport bool

cdef extern from "v8.h":
        cdef bool c_initx "v8::V8::InitializeICU"()

cdef class Script:
        def test(self):
                c_initx()

                return "wow"

编译过程没问题，但我无法导入helloworld：

Traceback (most recent call last):
  File "test.py", line 1, in <module>
    import helloworld
ImportError: /opt/cython/helloworld.so: undefined symbol: _ZN2v82V813InitializeICUEPKc

我使用github https://github.com/v8/v8

中的最新v8版本

Cython +外部c ++ lib
