Hi,

I'm trying to run my project, but Kawa gives the following complaint:

<unknown>: missing implementation for
Indexable.cursorUnder$St(gnu.math.RealNum,gnu.math.RealNum,java.lang.Object)java.lang.Object

The project consists of many classes, and it would be really helpful to
know which class misses the implementation of the method. Is there any
chance of getting that information?

Try the attached patch to see if you get a more helpful error message.

Hi,
sorry for the delayed response.
I managed to figure out the problem by other means.
However, I just checked to see whether your patch would have helped -- and
it worked!

The error message that I got was the following:

<unknown>: non-abstract class HeadTailSeparator is missing implementation
for
Indexable.cursorUnder$St(gnu.math.RealNum,gnu.math.RealNum,java.lang.Object)java.lang.Object

Thanks!

I checked in an improvement of this this.  My test program now emits:

/tmp/x.scm:2:2: non-abstract class Foo is missing implementation for java.lang.Runnable.run()void
/tmp/x.scm:5:4: non-abstract object is missing implementation for java.lang.Runnable.run()void
