Internal Compiler Error on Windows

[Thorpe, Michael]

Hi,

I'm trying to build the latest build of the scala compiler on windows, which is currently failing with:

[scalacfork] Compiling 103 files to c:\Users\Michael\scala\build\quick\classes\library

BUILD FAILED
c:\Users\Michael\scala\build.xml:517: java.lang.RuntimeException: Compilation failed because of an internal compiler error; see the error output for details.

are there any solutions to this problem?

Hi Michael,

It's hard to tell what exactly the problem is, as the stacktrace you pasted is from the build tool, not the actual compiler error.

Is there more output? Which revision are you trying to build? Is the JVM's maximum heap size at least 1GB?

If this is not a clean build, try removing the build directory and starting over.

cheers

Hi Michael,

Recently I tried to build Scala on Windows and faced the same error
(well, I assume it's the same, since, as Adriaan says, you haven't
posted the entire error log). My problem was in "Program Files"
fragment of the path to either Ant or Scala. IIRC, when I changed
ANT_HOME to C:\PROGRA~2\ant\ and SCALA_HOME to C:\PROGRA~2\Scala,
everything started working again.

Also, I got errors when trying to build Scala with JDK 1.7. It has
some weird problems with Swing, so I switched to JDK 1.6, and
everything was fine. I've heard that there's a separate branch for
building with JDK 1.7, but didn't check this myself.

Cheers,
Eugene

[Thorpe, Michael]

Yes, it's a problem with Swing. Will try dropping down to JDK 1.6 and see if that fixes it.

JDK 1.7 is not supported yet and there are known incompatibilities like
the one you mentioned below.
