GCJ bytecode -> native code compilation problems

[osgood]

Hello,

I'm trying to compile a Java bytecode to the native code. I have gcj working and I'm able to compile Java source code to the native code and run it without problems. However, when I take a detour and compile the Java source code to Java bytecode with Sun's javac and then compile this bytecode to the native code I'm getting these errors

Main.java: In class `Main':
Main.java: In method `Main.test(int)':
Main.java:47: error: cannot find file for class java.lang.StringBuilder
Main.java:57: error: class 'java.lang.StringBuilder' has no method named '<init>' matching signature '()
...

and many others. Now, I've studied the documentation and resources on the internet but I wasn't succesfull so far.

I tried to supply Sun's jre/rt.jar in the classpath but it didn't help.

Has anybody met and solved this problem?

Thank you,

David

FYI: I plan to compile Java bytecode for which I don't have the source code available, that's the reason why I'm taking the detour in my experiments...

There are some pretty good Java decompilers around, which can recreate the source from bytecode. So you could use these decompiled source files for your native compilation.
