我正在尝试使用 JOGL 通过命令行编译一个简单的程序。这真的行不通。我尝试按照官方文档的建议引用 jogl.all.jar、gluegen-rt.jar、nativewindow.all.jar 和 newt.all.jar，但编译器仍然找不到 JOGL 类。

这是代码：

import java.awt.Frame;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

import javax.media.opengl.GL;
import javax.media.opengl.GLAutoDrawable;
import javax.media.opengl.GLCanvas;
import javax.media.opengl.GLEventListener;

public class Test implements GLEventListener {

    public static void main(String[] args) {
        Frame frame = new Frame("JOGL Test");
        GLCanvas canvas = new GLCanvas();
        canvas.addGLEventListener(new Test());
        frame.add(canvas);
        frame.setSize(300, 300);
        frame.setVisible(true);
        frame.addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });
    }

    public void init(GLAutoDrawable drawable) {
    }

    public void reshape(GLAutoDrawable drawable, int x, int y, int width,
            int height) {
    }

    public void display(GLAutoDrawable drawable) {
        GL gl = drawable.getGL();
        gl.glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
        gl.glClear(GL.GL_COLOR_BUFFER_BIT);
        gl.glColor3f(1.0f, 1.0f, 1.0f);
        gl.glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);
        gl.glBegin(GL.GL_POLYGON);
        gl.glVertex2f(-0.5f, -0.5f);
        gl.glVertex2f(-0.5f, 0.5f);
        gl.glVertex2f(0.5f, 0.5f);
        gl.glVertex2f(0.5f, -0.5f);
        gl.glEnd();
        gl.glFlush();
    }

    public void displayChanged(GLAutoDrawable drawable, boolean modeChanged,
            boolean deviceChanged) {
    }

}

这是我用来编译它的：

javac -cp /jogl/lib/jogl.all.jar;/jogl/lib/gluegen-rt.jar;/jogl/lib/nativewindow.all.jar;/jogl/lib/newt.all.jar Test.java

java 编译器似乎完全忽略了我的类路径规范。

编辑： GL、GLAutoDrawable 和 GLEventListener 似乎很好，只是找不到 GLCanvas。查看 jogl.all.jar 内部，似乎没有 GLCanvas.class。

尝试其中的每一个，看看是否有效：

javac -cp \jogl\lib\jogl.all.jar;\jogl\lib\gluegen-rt.jar;\jogl\lib\nativewindow.all.jar;\jogl\lib\newt.all.jar Test.java

javac -cp ./jogl/lib/jogl.all.jar;./jogl/lib/gluegen-rt.jar;./jogl/lib/nativewindow.all.jar;./jogl/lib/newt.all.jar Test.java

javac -cp .\jogl\lib\jogl.all.jar;.\jogl\lib\gluegen-rt.jar;.\jogl\lib\nativewindow.all.jar;.\jogl\lib\newt.all.jar Test.java

Don't forget to use the os specific separators ("\" and ";" under Windows, "/" and ":" under Linux) and now jogl.all.jar has been renamed jogl-all.jar. You only need to put jogl-all.jar and gluegen-rt.jar in your classpath. gluegen-rt-natives-?-?.jar and jogl-all-natives-?-?.jar must be in the same directory but not in the classpath.
