【问题描述】：
如何配置 mingw32 以交叉编译适用于 Windows 的 Direct3D 应用程序？有没有可能？我实际上已经成功地编译了本教程中的代码：http://www.directxtutorial.com/Tutorial9/B-Direct3DBasics/dx9B4.aspx - 在 Kubuntu 上使用 Code::Blocks 和 i586-mingw32msvc-g++。我需要添加 #define UNICODE 并删除 #pragma ... 部分来执行此操作，并且我使用了 /usr/i586-mingw32msvc/include 中的头文件和 mingw 包中的库。
但是我无法编译本教程中的代码：http://www.directxtutorial.com/Tutorial9/B-Direct3DBasics/dx9B5.aspx
Mingw 没有d3dx9.h 文件。所以我已经安装了wine1.2-dev 包和wine 版本的Windows 相关头文件，但现在我有错误：

我必须通过 wine MS DirectX SDK 安装吗？用代码改变一些东西？我是 DirectX 和 Windows 相关的菜鸟，但我只想交叉编译一些简单的 D3D 示例并检查它是否有效。
