交叉编译Python设置 [英] Cross Compiling Python setup
问题描述
我正在尝试使用Mingw-w64在Ubuntu 14.04上构建GObject-Introspection.我目前正在运行64位Linux,并尝试为32位Windows目标进行构建.
I am trying to build GObject-Introspection on Ubuntu 14.04 using Mingw-w64. I am currently running 64bit Linux and trying to build for a 32bit Windows target.
我的第一次尝试是使用Wine中安装的Python 2.7.8,但是,这没有用,因为Python的路径分隔符设置为'\'(以及'\'),而不是Linux的'/'.因此,我尝试在Ubuntu中使用Python 2.7.
My first attempt used Python 2.7.8 installed in Wine, however, this did not work because Python's path separator was set to '\' (well '\') instead of Linux's '/'. Due to this I tried using the Python 2.7 in Ubuntu.
使用Ubuntu提供的Python不会超出配置步骤. Config.log显示以下内容:
Using the Python provided by Ubuntu doesn't get past the configuration step. Config.log shows the following:

我了解到pyconfig.h定义的平台之间存在一些差异.我是否应该像操作系统那样将这些文件收集到单独的目录中(/usr/include/x86_64-linux-gnu/python2.7/pyconfig.h)?什么是Python的正确设置,以便我可以交叉编译GObject-Introspection?
I understand that there are some differences between the platforms that pyconfig.h defines. Should I be gathering these files into seperate directories like the OS seems to be doing (/usr/include/x86_64-linux-gnu/python2.7/pyconfig.h)? What is the correct setup for Python so that I can cross-compile GObject-Introspection?

推荐答案
尝试将其插入到Makefile中:
Try to insert this into your Makefile:
CFLAGS+= \
-DHAVE_SSIZE_T \
-DPY_FORMAT_SIZE_T="l" \
-DPY_FORMAT_LONG_LONG="ll" \
