Thread: [xmlvm-users] C++ target support dropped

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

  When downloading the latest version of xmlvm, I see that the 
xmlvm2cpp/ branch
and the --target=cpp option have been removed.  Is C++ support no longer 
available
in xmlvm?

Thanks,
Andrew

that is correct. We are working hard on the C backend. The mid-term 
strategy is to make the C backend the main target. Eventually the 
Objective-C backend will also be removed. Note that both C++ and 
Objective-C are supersets of C, so nothing will be lost. In fact, the C 
backend is already the most complete code generation we have. It can 
cross-compile OpenJDK and will also soon feature a garbage collector.

When do you expect it to be ready? In a month, in 6, in 2 years?

I was wondering the same...
Since I'm using xmlvm for making a 100% opengl app and I'm coding in Scala I
had to change some of the java library and crosscompile some scala libs to
make it work, so I will have to do that again when changing to the C
backend. Should I change to C backend now or is it too early?

Guys: I'm happy to see that there is interest in the new C backend. The 
C code generation is mostly done. The big job ahead is to convert the 
Objective-C wrappers to the new C backend conventions. I hope that I 
will get some help doing this. I think that this conversion is completed 
within two months. In a couple of weeks I will send around some 
technical information regarding the new backend that should help those 
that plan to add new API. Right now I would suggest holding off on doing 
any improvements to the Objective-C backend.

How did you use Scala with XMLVM ?
Did you use ProGuard?
Can you give us an example?

Yes, but I only could compile a very simple project. I'm having several
problems so I will wait until the C backend is ready to continue with it.

I did also some basic tests on how to use Scala with xmlvm, and I was successful up to now, but with very limited code. 
What kind of problems did you have?

I suspect that these problems have nothing to do with the Obj-C backend, so either this might not be able to be addressed by XMLVM or, in any case, there is a need to keep it in mind.

Well, to be able to use scala I had to cross compile some of the scala
libraries. This libraries are writen upon java libraries, and the problem
I'm facing is that scala uses many functions that are nor implemented in the
objective-c xmlvm implementation of the java libraries. So I have to write
the missing functions, but since I will have to do it again with the new
backend then I decided to wait.
I wonder if the java libraries for the c backend will also be handwriten or
it will be cross compiled?

From my knowledge, the idea is to be automatically cross compiled!

Yes, the idea is to cross-compile everything in the java.* namespace.

Great, so I will be able to cross compile the scala libs and everything will
work?

Crossing your fingers would be advisable when you attempt this, but in
theory the C backend should be able to deal with this.
