Windows 用の Direct3D アプリをクロスコンパイルするように mingw32 を構成する方法は? 可能性はありますか？私は実際にこのチュートリアルからコードをコンパイルすることに成功しました: http://www.directxtutorial.com/Tutorial9/B-Direct3DBasics/dx9B4.aspx - i586-mingw32msvc-g++ で Kubuntu で Code::Blocks を使用します。これを行うには、パーツを追加#define UNICODEおよび削除する必要があり#pragma ...、/usr/i586-mingw32msvc/include のヘッダー ファイルと、mingw パッケージのライブラリも使用しました。
ただし、このチュートリアルのコードをコンパイルできません: http://www.directxtutorial.com/Tutorial9/B-Direct3DBasics/dx9B5.aspx
Mingw にはファイルがありませんd3dx9.h。wine1.2-devそのため、Windows 関連のヘッダー ファイルのワイン バージョンを含むパッケージをインストールしましたが、エラーが発生しました。

wine MS DirectX SDK を介してインストールする必要がありますか? コードで何かを変更しますか？私は DirectX および Windows 関連の初心者ですが、D3D のいくつかの簡単な例をクロスコンパイルして、これが機能するかどうかを確認したいだけです。
