交叉编译Python扩展 [英] Cross Compiling Python Extensions

问题描述

我在Buildroot Linux发行版的ARM（Python 2.7.2）下交叉编译netifaces扩展时遇到问题。根据此博客， http://whatschrisdoing.com/blog / 2009/10/16 / cross-compiling-python-extensions / 我已经定义了CC，LDSHARE等环境变量，但是distutils / setuptools没有考虑CC，因此所有测试都会失败：

I have a problem with cross-compiling netifaces extension under Buildroot Linux distro for ARM (Python 2.7.2). According to this blog http://whatschrisdoing.com/blog/2009/10/16/cross-compiling-python-extensions/ I've defined CC, LDSHARE etc. environment variables, but distutils/setuptools doesn't take CC into account so all tests will fail:

是否还有其他交叉编译示例/教程还是我在做什么错？

Are there any other cross-compile examples/tutorials or what am I doing wrong?

推荐答案

请确保已安装 distutilscross软件包，如您所链接的文章中所述。这将添加-x选项并支持PYTHONXCPREFIX / LDSHARED / etc环境变量。

Make sure you have installed the distutilscross package as noted in the article you linked. This adds the -x option and support for PYTHONXCPREFIX/LDSHARED/etc environment variables.
