Errors in scala-virtualized compilation

[Lin Huang]

Dear All,


I am trying to compile scala-virtualized downloaded from
https://github.com/TiarkRompf/scala-virtualized with ant fastdist.
However, I got the following errors. I cannot figure out how to fix
it. Any suggestions or comments will be highly appreciated. For your
reference, Java 1.7.0, Scala 2.8.1 final, Ant 1.7.1 are installed on
my computer with OS Ubuntu 10.04 lucid.

Well, first problem I can see immediately is that I doubt that people
working on virtualized Scala are using java 1.7.0.
With that said, I will leave the explanation of error you get to people
working on it because I haven't been following that code recently.

Hi,

Please use Java 6, building on Java 7 is not in master yet (see https://issues.scala-lang.org/browse/SI-3634)

There's also a branch that's merged with a more recent scalac at https://github.com/adriaanm/scala-dev/tree/virtualized-master

If you really need to build on Java 7, you could try merging that virtualized-master above with https://github.com/adriaanm/scala-dev/tree/openjdk 

cheers
