我想使用 Cython 将多个 .pyx 文件转换为可执行包(.DLL)。
如何通过 distutils 从多个 .pyx 创建单个 Windows DLL?
使用的样本:
sub1.pyx:
cimport sub1
class A():
def test(self, val):
print "A", val
sub1.pxd:
cdef class A:
cpdef test(self,val)
sub2.pyx:
cimport sub2
class B():
def test(self):
return 5
sub2.pxd:
cdef class B:
cpdef test(self)
初始化.py:
cimport sub1
cimport sub2
import sub1
import sub2
设置.py:
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
ext_modules = [Extension("sub", ["__init__.pyx", "sub1.pyx", "sub2.pyx"])]
setup(
name = 'Hello world app',
cmdclass = {'build_ext': build_ext},
ext_modules = ext_modules
)
错误:
sub1.obj : error LNK2005: ___pyx_module_is_main_sub already defined in __init__.obj
sub1.obj : error LNK2005: _initsub already defined in __init__.obj
sub2.obj : error LNK2005: ___pyx_module_is_main_sub already defined in __init__.obj
sub2.obj : error LNK2005: _initsub already defined in __init__.obj
