Suddenly I get the infamous "java.lang.Object cannot be resolved" when building on amd64. Any ideas?

I'm not using any chroots or anything.

~$ /usr/lib/jvm/java-gcj/bin/javac Test.java
----------
1. ERROR in Test.java (at line 1)
public class Test

FWIW, I'm also seeing something like this, building inside a pbuilder
environment on x86 for a package that uses java-gcj-compat-dev.

Is this an amd64 machine with a 32-bit Debian version installed and
64-bit kernel running? If thats the case install the linux32 package
and run it.

The problem is that some parts of gcj are installed in
/usr/lib/gcc/i486-linux-gnu/4.1 (on my machine). On amd64 this dir is
named differently. gcj always uses what

dpkg-architecture -qDEB_BUILD_GNU_TYPE

returns. When using the linux32 wrapper on an amd64 machine you will get
"i486-linux-gnu"


Cheers,
Michael

No, this is pure amd64.
