Is GCJ still active?

Is GCJ still active?

[孙波翔]

Hi there!
Thank you to read the email.

I am doing a project(open source) and need to complie some java
*.class files to *.dll and *.so files so that this files can run
without jre.

I found there only have to tools can do it: Jet and GCJ.

Jet is not under GPL license. And the latest release of GCJ was on Sep
22, 2009. I need to compile the java files and support JDK 1.7
features. So does GCJ still active and may support JDK 1.7 in future?
Or could you suggest some other tools can do it?

Thanks again!
Waiting for your reply.
Sun

gcj ahas been released several times since then.  There is a little
development still going on, but at present there are no plans to do
a release that supports Java 1.7 features.

So naturally, the next question then would be:

Will there be any capabilities to compile java applications to native
binaries using the OpenJDK? If not, who should we contact to convey
the ever so popular and growing interest in being able to do this for
Linux, OS X and Windows?

Never say never, but I am not aware of any such thing.

I'm not sure.  I suppose the key question is how much mone you are
prepared to spend, but that's probably off-topic for this list.  There
are some areas in which a precompiler like gcj is advantageous, but
they are fairly specialized.

Avian[1] will do this well enough to run e.g. Eclipse, Tomcat, Jython, 
etc., but I haven't tested any Swing/AWT apps yet.  OpenJDK 6 is 
supported, and I've just started on a OpenJDK 7 port.

Hi Joel,

Congratulations for this excellent project!!

If I understend, it's possible to compile java code to binary code?

A SWT application runs with avian?

Thank you

Yes, Avian supports either JIT (just-in-time) or AOT (ahead-of-time) 
compilation to machine code, or a mix of both.

> A SWT application runs with avian?

Yes.

Please direct any further questions or comments about Avian to 
avian@googlegroups.com, since they're off-topic for this list.  Thanks.
