Hi,

I am trying to build VTK (http://www.vtk.org/). I have no problems 
compiling this package on x86 by either using emerge or manually. But on 
amd64 the build dies because of an java.lang.OutOfMemoryError:

(...)
Listing /var/tmp/portage/vtk-5.0.0-r4/work/VTK/Wrapping/Python/vtk/wx ...
Compiling /var/tmp/portage/vtk-5.0.0-r4/work/VTK/Wrapping/Python/vtk/wx/__init__.py ...
Compiling /var/tmp/portage/vtk-5.0.0-r4/work/VTK/Wrapping/Python/vtk/wx/wxVTKRenderWindow.py ...
Compiling /var/tmp/portage/vtk-5.0.0-r4/work/VTK/Wrapping/Python/vtk/wx/wxVTKRenderWindowInteractor.py ...
...
Generating ../../java/vtk/vtkBuildAllDriver.class


The system is out of resources.
Consult the following stack trace for details.
java.lang.OutOfMemoryError
make[2]: *** [java/vtk/vtkBuildAllDriver.class] Error 3
make[1]: *** [Wrapping/Java/CMakeFiles/VTKBuildAll.dir/all] Error 2
make: *** [all] Error 2


The build consequently breaks down here. However, when I run make again, 
it suddenly compiles withtout problems and finishes the build.

The compilation command for building vtkBuildAllDriver.class is:

(...)
@echo "Generating ../../java/vtk/vtkBuildAllDriver.class"
cd /var/tmp/portage/vtk-5.0.0-r4/work/VTK/Wrapping/Java && /opt/blackdown-jdk-1.4.2.03/bin/javac -classpath 
/var/tmp/portage/vtk-5.0.0-r4/work/VTK/java/vtk/.. -d /var/tmp/portage/vtk-5.0.0-r4/work/VTK/java/vtk/.. 
/var/tmp/portage/vtk-5.0.0-r4/work/VTK/java/vtk/vtkBuildAllDriver.java


I have tried to increase the amount of memory java can use by adding 
-J-Xms48m to the command (right after configuration, since a second 
compilation attempt always works), but without succes.

Does anyone have an idea what the problem can be? I am unsure if the 
problem lies within VTK or Blackdown. Sun-jdk does not have a 64 bit 
version available, so I cannot compare with that.

I have previously posted this to

Thanks in advance,
