C++ Interpreter on amd64

[Volker Simonis]

Hi,

a while ago I managed to build the C++ Interpreter on 64-bit Sparc. I
had to apply some patches though, and I'm not sure if all of them have
been integrated into the OpenJDK, so you may want to have a look:
http://weblogs.java.net/blog/simonis/archive/2007/11/template_vs_cin_1.html
The SPARC patches may also give you an idea what you may have to change for x64.

I would also recommand you read Gary Bensons blog
(http://gbenson.net/)  about Zero, his C++Interpreter port. I think
you should be able to build Zero on all platforms, but I never tried
it.

Regards,
Volker
