ゲームの構築を支援するために、physgameengine と呼ばれるライブラリを構築しています。このゲーム ライブラリは、ライブラリ ファイル libOgreMain-1.6.5.so、libBulletCollision.a、libBulletDynamics.a、libBulletSoftBody.a、libSDL-1.2.so.0 にある Ogre3d、Bullet Physics、SDL などの複数のライブラリとリンクしています。 . この Library/Shared オブジェクトは、GCC と Code::blocks を使用して、Ubuntu 9.10 で問題なくビルドされているようです。mingw と Code::blocks を使用して Windows で問題なくビルドできます。
ウィンドウでは、ビルドしたライブラリを使用してコンパイル/リンクするゲームを作成できます。これらのプログラムは実行され、期待どおりに動作します。Ubuntu で、このライブラリを使用するゲームをコンパイル/リンクしようとすると、多くの未定義の参照エラーが発生します。しかし、私が構築したライブラリ内の関数やオブジェクトではなく、私のライブラリが呼び出すアイテムに対してです。これは私が得るエラーの例です。

コードの大部分は、Windows と Linux で同じであり、同等のコンパイル/リンカー設定があるようです。しかし、Linux ゲームは、私のライブラリがリンクすべき元のライブラリにリンクしているようです。何が起こっている?それを修正する方法についてのアイデアはありますか?
