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 并尝试为 32 位 Windows 目标构建。

我的第一次尝试是使用安装在 Wine 中的 Python 2.7.8，然而，这不起作用，因为 Python 的路径分隔符设置为 '\'（好吧 '\'）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 不会通过配置步骤。 Config.log 显示如下：

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:

 #       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
   ^

我了解 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做的单独目录中（/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？

尝试将其插入到您的 Makefile 中：

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