如何将包含本机调用的* .jar转换为DLL（Mono C＃）

Question

We're using IKVM to convert our *.jar to dll that we using to migrate our code to C# with Mono.. We have a problem especially when working with jar contains a JNI call, expl JnativeHook , its make an error when we try to convert it using IKVM, i have reported the error to the author as the follow:

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).

As you can see the author has respond with a few words without giving us a solution..

What i understand is the embedded Dll make the error, in fact IKVM does not know how to work with it(inside the JAR)...

there is some suggestions to solve this problem? PS: what does mean Fixed in cvs ? Thank you.

Answer 1

The cause of the problem is that you have no write rights to the output location. Run the command on another location with write rights.

I think the fix will only prevent the "INTERNAL COMPILER ERROR" message.
