Question

我们正在使用IKVM将我们的* .jar转换为我们使用Mono将代码迁移到C＃的dll。我们遇到一个问题，特别是在使用jar包含JNI调用时，浏览JnativeHook，当我们尝试使用IKVM转换它时会出错，我已将错误报告给作者，如下所示：

I'm trying to use JnativeHook.jar library, its work for my java apllications, However:
 Not: JnativeHook its a cross-platform containes  3 .dll  depends on the OS when the java application is running (dynamic loading of *.dll)...
JnativeHook.jar containes also  a package(demo) that containes a main classe, i have solved this problem by deleting this one, now i'm sure that will be converted to dll...
finally, when i try to convert this one to .dll i get this error:

C:\Users\marwen\Desktop\Kid protector\Tools and IDE\ikvmbin-7.2.4630.5\bin>ikvmc JNativeHook.jar

Message:
Thanks. Fixed in cvs. BTW, the error is because ikvmc can't write to
JNativeHook.dll (probably because you don't have write access to the
directory).

正如您所看到的，作者在没有给我们解决方案的情况下回答了几句话。

我所理解的是嵌入式Dll会产生错误，实际上IKVM不知道如何使用它（在JAR内部）......

有一些建议可以解决这个问题吗？ PS：什么意思是Fixed in cvs？谢谢。

问题的原因是您没有输出位置的写权限。在具有写权限的其他位置上运行该命令。

我认为该修复只会阻止“内部编译器错误”消息。

如何转换包含对DLL的本机调用的* .jar（Mono C＃）
