我有一个使用WAF的项目（不是我发起的项目）。有些人打算在Windows上编译项目，在Linux上编译一些项目，在OS X上编译一些项目。在OS X上编译的那些可能使用MacPorts，其他人使用Homebrew，其他人可能使用安装在import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.EventQueue;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Point;
import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionListener;
import java.awt.image.BufferedImage;
import javax.swing.Icon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.UIManager;

public class Grid extends JPanel implements MouseMotionListener {
private static final String NAME = "OptionPane.informationIcon";
private static final Icon ICON = UIManager.getIcon(NAME);
private static final int SCALE = 8;
private final BufferedImage image;
private int imgW, imgH, paneW, paneH;
public Grid(String name) {
super(true);
imgW = ICON.getIconWidth();
imgH = ICON.getIconHeight();
image = new BufferedImage(imgW, imgH, BufferedImage.TYPE_INT_ARGB);
Graphics2D g2d = (Graphics2D) image.getGraphics();
ICON.paintIcon(null, g2d, 0, 0);
g2d.dispose();
this.addMouseMotionListener(this);
}
@Override
public Dimension getPreferredSize() {
return new Dimension(imgW * SCALE, imgH * SCALE);

paneW = this.getWidth();

Point p = e.getPoint();
int x = p.x * imgW / paneW;
int y = p.y * imgH / paneH;

this.setToolTipText(x + "," + y + ": "

}
@Override

private static void create() {
JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.add(new Grid(NAME));
f.add(new JLabel(ICON), BorderLayout.WEST);
f.pack();
f.setVisible(true);
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override

});
}
}
中的自定义编译库。
我宁愿不将/usr/local等路径硬编码到/opt/local中。在OS X上支持所有这些不同包管理器的最佳实践是什么？我刚刚开始了解WAF，BTW。是否有wscript或其他一些选项允许WAF在--prefix中查找标题和库？是否所有正在编译项目的用户都需要设置环境变量，例如：
/opt/local
