Hi,

I’m a technical administrator and not a developer so I do hope you will bear with me as I try to orient myself with ikvm and the task I’m trying to navigate through:)

I have a need to access Java classes from .Net assemblies on Win XP. My investigations led me to ikvm and I was very impressed with the concept – just right for me. However, installation and build is proving problematic. Here’s what I’ve done up to now:

- Downloaded and installed ikvm release 0.36.0.11

- Downloaded and installed NAnt 0.85

- Downloaded ecj.jar and dumped it in $ikvmhome/bin

- Downloaded various versions of GNU classpath and extracted, in turn to peer level directory of $ikvmhome (named classpath)

When I try to compile ecj.jar I get:

Warning IKVMC0105: unable to compile class “org.eclipse.jdt.core.JDTCompilerAdapter”

(missing class “org.apache.tools.ant.taskdefs.compilers.DefaultCompilerAdapter”)

Warning IKVMC0100: class “org.eclipse.jdt.core.JDTCompilerAdapter” not found

I’ve also noticed that IKVM.GNU.Classpath.dll doesn’t exist in the distribution I have. It’s not clear from what I’ve read but I assume I have to compile this in, even though a

Preexisting classpath folder and build file exists. Some things have led me to believe it should be there while others lead me to believe I have to download classpath and compile it. Anyway, I’ve tried building Classpath version 0.95-0.98 without success (using NAnt) – each reporting one class or another missing.

So, in a nutshell, I would greatly appreciate it if someone could provide me with the guidance that will take me beyond where I am. Many thanks in advance for any assistance received.

Regards,

David

Hi,

You should just ignore the warning. It means that ecj.jar contains a reference to an Eclipse class that you don't have, but that doesn't matter because that class is only used when the compiler is run embedded in Eclipse.

Jeroen
