2.8 gives internal compiler error on 2.7 code

Scala User

Dear all,
I'm using netbeans 7.1 and currently testing 6.8 RC1.
On both versions I use the respective netbeans plugins for scala.

I'm trying to compile the project developed under 2.7 (which works fine) with 2.8, but I get the following internal compiler error:

Does anybody have an idea?

Here are the implicit conversions I do (if this could be the problem):

    class RichObjectSet[T](objectSet:ObjectSet[T]) extends Iterator[T] {

        def next:T = objectSet.next()

    implicit def toRichObjectSet[T](objectSet: ObjectSet[T] ) = new RichObjectSet[T](objectSet)

    class RichFCollection[T](coll:FCollection[T]) extends Iterator[T]{
        def hasNext:Boolean = coll.iterator.hasNext()
        def next:T = coll.iterator.next()
    }
    implicit def toRichFCollection[T](coll:FCollection[T] ) = new RichFCollection[T](coll)

Thank you,

Have you tried to clearn all class files? Ie, are you building it from a clean source tree, without any left-overs from compilation with 2.7?

Also check your stack size settings. I got the same errors when doing Scala
builds with Ant in Eclipse while the same code compiled fine in the IDE. I
had to increase the JVM stack size of the Ant process to something bigger
than the default (think I used 1M). That solved it.

Also try:

To see which class that is under loading causes the error message.

Re: 2.8 gives internal compiler error on 2.7 code (Netbeans)

Added by boris pezzatti on 2009-12-09, 22:37

So I'm back after a tour in bug reporting .... which resulted to be invalid ...
from the command line (without ant) it is possible to run the code, after setting

export JAVA_OPTS="-Xms512m -Xmx2056m -XX:MaxPermSize=512m -Xss1M -server"

Apparently this was not necessary in my case with scala 2.7.7.

The problem is that I still get the error in the Netbeans IDE.
I tried to set the JAVA_OPTS and the ANT_OPTS, but this didn't solve it.
Also setting the jvm options in the netbeans.conf file was not enough.

I noticed that in the project properties it is possible to set the compiler options, but not the compiler environment (like e.g. JAVA_OPTS for scalac). Does anybody know where scalac take his environment paramenters?

It it crashes the compiler then it's a bug in the compiler. If your code is invalid then the compiler should be giving you an error message, not exploding.

Please file a ticket in Trac.

Does anybody have an idea?

Here are the implicit conversions I do (if this could be the problem):

    class RichObjectSet[T](objectSet:ObjectSet[T]) extends Iterator[T] {
        def hasNext:Boolean = objectSet.hasNext()
        def next:T = objectSet.next()
    }
    implicit def toRichObjectSet[T](objectSet: ObjectSet[T] ) = new RichObjectSet[T](objectSet)

    class RichFCollection[T](coll:FCollection[T]) extends Iterator[T]{
        def hasNext:Boolean = coll.iterator.hasNext()
        def next:T = coll.iterator.next()
    }
    implicit def toRichFCollection[T](coll:FCollection[T] ) = new RichFCollection[T](coll)

Thank you,
Boris

Re: 2.8 gives internal compiler error on 2.7 code

Added by Caoyuan on 2009-12-03, 16:47

Scala-2.8.0 is not compatible with 2.7.x, do not use compiler of
Scala-2.8.0 to compile 2.7.x code.

oops, the correct statement should be:
Scala 2.8.0 is not compatible with classes compiled under 2.7.x. You
should check if your project depends on classes/jars that were
compiled under 2.7.x, if so, may need to re-compile the sources of
classes/jars under 2.8.0 too.

Re: 2.8 gives internal compiler error on 2.7 code

Added by boris pezzatti on 2009-12-04, 09:17

Actually the project is made by only 3 scala classes and all the dependencies are java ones.
All the classes were cleaned and also compiling in a terminal gives the same error ...

... I think I will have to fire a bug.

Thank you all.

cheers,
boris

Does anybody have an idea?

        def next:T = objectSet.next()

        def next:T = coll.iterator.next()
    }
    implicit def toRichFCollection[T](coll:FCollection[T] ) = new

Re: 2.8 gives internal compiler error on 2.7 code

Added by Caoyuan on 2009-12-04, 13:37

I recalled I encountered similar error message before, it may be
caused by that the SCALA_HOME pointed to a version of Scala runtime,
but the PATH pointed to another version of scala's runtime bin
directory. I can not remember what was the exactly condition now.

Re: 2.8 gives internal compiler error on 2.7 code

Added by boris pezzatti on 2009-12-04, 16:07

I tried both from a terminal:
- without setting PATH and SCALA_HOME
- setting them (PATH to $SCALA_HOME/bin

but both always give the same error.

To Silvio:
Is your comment valid also if I compile from a terminal? How can I set the JVM stack size? (sorry ... I'm quite a newbie ...)

Thanks
Boris

The following error occurred while executing this line:
/home/pezzatti/wsl/dev/dbFuel/ImporterScala/nbproject/build-impl.xml:236:
Compilation failed because of an internal compiler error; see the error
output for details.
BUILD FAILED (total time: 7 seconds)

Does anybody have an idea?

Here are the implicit conversions I do (if this could be the problem):

    class RichObjectSet[T](objectSet:ObjectSet[T]) extends Iterator[T] {
        def hasNext:Boolean =  objectSet.hasNext()
        def next:T = objectSet.next()
    }
    implicit def toRichObjectSet[T](objectSet: ObjectSet[T] ) = new
RichObjectSet[T](objectSet)

    class RichFCollection[T](coll:FCollection[T]) extends Iterator[T]{
        def hasNext:Boolean =  coll.iterator.hasNext()
        def next:T = coll.iterator.next()
    }
    implicit def toRichFCollection[T](coll:FCollection[T] ) = new
RichFCollection[T](coll)



Thank you,
Boris

Re: 2.8 gives internal compiler error on 2.7 code

Added by Ricky Clarkson on 2009-12-03, 16:57

Compiling 2.7 code and examining the output is a pretty normal way of
finding out what you need to change.

In any case, bug reports go in Trac, rather than getting lost in scala-user.
