UnsatisfiedLinkError用在Mac OS X中使用NetBeans

分类: 技术问答 • 2022-09-19 11:16:26
问题描述：

我正经历着类似的问题，这个问题sqlite4java罐：UnsatisfiedLinkError用在Mac OS X中使用NetBeans

UnsatisfiedLinkError with sqlite4java Jar on Mac OS X

不过，我在Mac上运行，而我有相关的库在我的lib夹。但是，如果我按原样运行，则会得到UnsatisfiedLinkError。如果我运行“Java的罐子sqlite4java.jar -d”我得到以下输出：

sqlite4java 282

我可以看到它正在寻找sqlite4java-OSX-x86_64的库，所以我然后跑都“LN - 小号libsqlite4java-osx.jnilib libsqlite4java-OSX-x86_64.jnilib”和 “LN -s libsqlite4java-OSX-10.4.jnilib libsqlite4java-OSX-x86_64.jnilib” 这似乎帮助：

似乎罚款，对？不。当我尝试运行我的java代码时，尝试使用UnsatisfiedLinkError打开数据库时又失败了。

有什么明显的我失踪了吗？下面是相关部分的LS我的lib目录只是作为一个全面的检查：

和我的数据库连接代码的副本：

     } catch (SQLiteException ex) { 
      Logger.getLogger(Database.class.getName()).log(Level.SEVERE, null, ex); 
     } 
    } 
}

感谢你对我的问题有何启示...

你可以在这个其他堆栈溢出的答案中看到这个问题，它还包括如何根据需要以编程方式设置'java.library.path'：http://stackoverflow.com/a/35353377/3679676 – 2016-02-12 03:03:03

这是解决方案：

Exception in thread "main" com.almworks.sqlite4java.SQLiteException: 
[-91]cannot load library: java.lang.UnsatisfiedLinkError: no sqlite4java-osx-x86_64 
in java.library.path

请尝试运行以下命令：

java -jar sqlite4java.jar -d

，使其尝试加载的二进制文件的所有变体和验证结果。

其结果必然是这样的：

java -jar sqlite4java.jar -d

这些文件试图更具体的顺序不太具体。所以订单是正确的。

的问题是，有没有 - 所以我们可能需要重命名libsqlite4java-osx.jnilib到libsqlite4java-OSX-amd64.dylib更具体的二进制文件。

我已经在命令行上输出了类似的内容，我已将它包含在我的问题中，这是我尝试在NetBeans中的代码中使用库，我看到错误 – frak 2014-03-04 19:19:38

您必须将libsqlite4java-osx.jnilib重命名为libsqlite4java-osx-amd64.dylib（对于Mac OSX） – 2014-03-05 09:30:24

噢，我现在看到，这也可以用作解决方案 - 抱歉没有看到你写的是正确的 – frak 2014-03-05 18:43:43

答

不知道究竟出了什么问题，但你可以尝试从程序内运行sqlite4java的诊断代码，看看它是否显示了相同的加载顺序：

public Database() { 
    com.almworks.sqlite4java.SQLite.main(new String[] {"-d"}); 
    db = new SQLiteConnection(new File("./test.db")); 
    ...

我已经添加上面的代码，可以看到它没有找到任何库 - 我可以让它们在那里，所以我真的不知道如何继续...... – frak 2013-03-22 16:16:09

答

升级到Mountain Lion后，我的程序出现同样的错误。当我添加库到 /库/ Java /扩展 他的程序运行良好。我不知道这是最好的解决方案，但它工作。

这是我在Eclipse上唯一的工作。谢谢！ – Thunderforge 2014-02-23 04:11:41

对不起，当你回答时，我一定错过了你的答案。它确实有效，但查看输出结果让我知道发生了什么问题...... – frak 2014-03-04 21:02:14

答

我有同样的问题，但设法通过从IDE创建libs文件夹，然后将该jar复制到新的libs文件夹来加载sqlite。然后，我从构建路径中删除旧版本的jar，并添加到新版本中。希望这可以帮助！
