Hello all, I would like informations, please, about gcj on windows. In mingw this module (gcc-java) appears not available. Is possible actually developing applications with gcj on windows? -- Thanks in advanced Luciano David
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

So does GCJ still active and may support JDK 1.7 in future? 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. Andrew.

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? -- Harpal Grover President Harpal Grover Consulting Inc(Continue reading)

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?

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 <at> googlegroups.com, since they're off-topic for this list.

Hi, I am wondering if we can use methods from a gcj-compiled library in uncompiled Java program(bytecode) executed on a VM. According to gcj FAQ 1.7, there is no problem to do this with 'gij' interpreter/runtime. You can compile some Java code into library (native code), and run bytecode with 'gij' to invoke library methods. But this seems only capable for 'gij', and other runtimes like HotSpot cannot load and link the library properly. I want to know if there is a general solution to allow you interface uncompiled Java program with gcj-compiled library. Any information or reference about this will be appreciated. Many Thanks, Yi
I suggest you try jni to get to whatever native code you are interested in.
