ohhh, sorry about that :-)

anyway, I can't build the native part of harmony/classlib

doing "ant build-native" results in

  classlib/depends/libs/linux.x86_64

not being found.

If I try to make a symlink between linux.x86_64 and linux.x86_32 (no
idea what I'm doing here, just trying things out), I get

build-native:

googling it up a little finds

 http://sources.redhat.com/ml/binutils/2005-04/msg00649.html

which is a reference to a GCC bug that was apparently fixed a long time go.

Ah btw,

[stefano@harmony-em64t] ~/src/harmony/classlib $ gcc --version
gcc (GCC) 4.0.3 (Ubuntu 4.0.3-1ubuntu5)

[stefano@harmony-em64t] ~/src/harmony/classlib $ ld --version
GNU ld version 2.16.91 20060118 Debian GNU/Linux

[stefano@harmony-em64t] ~/src/harmony/classlib $ uname -a
Linux harmony-em64t 2.6.15-27-amd64-generic #1 SMP PREEMPT Sat Sep 16

Please, bare with my ignorance, I have *zero* knowledge on native stuff
(I moved from x86 assembly on windows to java without going thru C ;-)

No idea what to do now, please help and I can reward you with a freshly
juiced gump run :-)

Stefano.
