<mini> BridJ、動かした話。

　BridJ、2 か月以内ぐらいに変更があるのでどうやらまたきちんと管理されているらしい。

　とりあえず最新版の 0.7 PRE 使ってみました。BridJ エラーで動かないなぁ、って思ってたら、DLL を作る方法を忘れていた、だけでした。

　Windows では __declspec( dllexport ) つけねーといけないんだわ！

　これで結構悩みました。最後にコード貼っておきます (自動生成も含めて)

Main.java

package com.mntone;

import test.TestClass;

public class Main
{
    public static void main( String[] args )
    {
        final TestClass nativeTestClass = new TestClass();
        nativeTestClass.run();
    }
}

TestLibrary.java

package test;

import org.bridj.ann.Library;
