交叉编译Python设置

Question

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并尝试构建32位Windows目标。

我的第一次尝试使用了Wine中安装的Python 2.7.8，然而，这不起作用，因为Python的路径分隔符设置为'\'（好'\'）而不是Linux的'/'。因此，我尝试在Ubuntu中使用Python 2.7。

使用Ubuntu提供的Python不会超过配置步骤。 Config.log显示以下内容：

In file included from /usr/include/python2.7/Python.h:8:0,
                 from conftest.c:40:
/usr/include/python2.7/pyconfig.h:78:3: error: #error unknown multiarch locatio#
 # error unknown multiarch location for pyconfig.h
   ^
In file included from /usr/include/python2.7/pyport.h:4:0,
                 from /usr/include/python2.7/Python.h:58,
                 from conftest.c:40:

   ^

                 from conftest.c:40:
/usr/include/python2.7/pyport.h:241:9: error: #error "This platform's pyconfig.#
 #       error "This platform's pyconfig.h needs to define PY_FORMAT_SIZE_T"
         ^
In file included from /usr/include/python2.7/pymath.h:4:0,
                 from /usr/include/python2.7/Python.h:77,
                 from conftest.c:40:
/usr/include/python2.7/pyconfig.h:78:3: error: #error unknown multiarch locatio#
 # error unknown multiarch location for pyconfig.h
   ^

据我所知，pyconfig.h定义的平台之间存在一些差异。我是否应该将这些文件收集到操作系统似乎正在进行的单独目录中（/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？

尝试将其插入Makefile：

CFLAGS+=        \
                -DHAVE_SSIZE_T \
                -DPY_FORMAT_SIZE_T="l" \
                -DPY_FORMAT_LONG_LONG="ll" \
