问题导入子进程32

我想通过buildroot安装我的python 2.7安装的subprocess32。它似乎正确安装，但是当我将其导入嵌入式系统上我得到一个错误：问题导入子进程32

>>> import subprocess32 
/usr/lib/python2.7/site-packages/subprocess32.py:472: RuntimeWarning: The _posixsubprocess module is not being used. Child process reliability may suffer if your pro 
gram uses threads. 
    "program uses threads.", RuntimeWarning)

这条路我试图导入_posixsubprocess

import _posixsubprocess 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
ImportError: dynamic module does not define init function (init_posixsubprocess)

subprocess32似乎有它自己的版本，它的在这种情况下不工作？

这里是我的make文件：

############################################################# 
# 
# Subprocess32 module for python 
# 
############################################################# 

SUBPROCESS32_VERSION = 3.2.7 
SUBPROCESS32_SOURCE = subprocess32-$(SUBPROCESS32_VERSION).tar.gz 
SUBPROCESS32_SITE = https://pypi.python.org/pypi/subprocess32 

SUBPROCESS32_DEPENDENCIES = python 

define SUBPROCESS32_BUILD_CMDS 
     (cd $(@D); $(HOST_DIR)/usr/bin/python setup.py build) 
endef 

define SUBPROCESS32_INSTALL_TARGET_CMDS 
     (cd $(@D); $(HOST_DIR)/usr/bin/python setup.py install --prefix=$(TARGET_DIR)/usr) 
endef 

$(eval $(call GENTARGETS,package,subprocess32))

有关于这Python Error The _posixsubprocess module is not being used但是答案是它是死的评论链接一个类似的帖子。我的问题有什么想法？

setup.py：

#!/usr/bin/python

from distutils.core import setup, Extension 


def main(): 
    if sys.version_info[0] != 2: 
     sys.stderr.write('This backport is for Python 2.x only.\n') 
     sys.exit(1) 

    ext = Extension('_posixsubprocess', ['_posixsubprocess.c'], 
        depends=['_posixsubprocess_helpers.c']) 
    if os.name == 'posix': 
     ext_modules = [ext] 
    else:

问题是distutils正在使用错误的编译器来构建共享对象（其他对象使用了正确的编译器）。在构建阶段设置如下LDSHARED变量来解决这个问题：

LDSHARED="$(TARGET_CC) -pthread -shared"

我不知道你使用的Buildroot里面的版本，但如果它仍然使用了GENTARGETS宏版本和不具备python-package基础设施，然后它必须是一个真正的，真正的旧版本。请先升级，最近几年在Python支持中已经提供了许多修复程序。

说实话，我甚至不知道它是什么版本的buildroot的，是的，它是旧的，但升级它不是现在的选项。我不确定问题是否与它或subprocess32一样。这个重大变化会引起许多其他问题，我想也是如此。 – Paul
