Calico Java stopped working on Mac/Windows

[Doug Blank]

Since the update of the IKVM libraries from Mono for Calico Java, Calico Java has stopped working on Mac and Windows. Related to #3 and #4.

Before: starting calico with Java enabled gave no error message

Now: starting calico with Java enabled gives: "An exception was thrown by the type initializer for edu.rice.cs.dynamicjava.Options"

>>> import clr
>>> clr.AddReference("drjava")
>>> import edu
>>> options = edu.rice.cs.dynamicjava.Options.DEFAULT

Maybe just rebuild drjava.dll?

[Keith O'Hara]

I tried that. No go. I think its a .net 4 compatibility thing.

Should I used gmcs or dmcs? I think its a 2.0 vs 4.0 problem.

[Keith O'Hara]

Running with --runtime=4.0 made the Missing method warning/error go away but the exception remains. So weird that it runs fine on linux but not on mac os x.

I created a small driver C# app and I got this mammoth error:

OK I rebuilt ikvm with .net 2.0 support (it was using 4.0 before) and the problem is fixed.

ikvm-fork>nant -t:mono-2.0

For some reason the 4.0 implementations were acting differently on Mac and Windows compared with Linux. Even though they were the exact same version (.NET 4.0.30319.1).

This current version of the java dll's checked in work with java and ROS.

[Doug Blank]

Excellent! We could put a Makefile in the dir:

wget http://lib nant -t:mono-2.0

[Keith O'Hara]

Need to test on Windows.

[Doug Blank]

It works for me under Windows!
