[javaCompiler-users] Building a DLL with JavaCompiler?

[Jesper J. / S. G. <je...@so...>]

Hi

I am having problems getting a DLL to work with JavaCompiler 0.7 and 
0.8, and I wonder if somebody has a suggestion for how to get it to work.

I hope someone has an idea of whether this is a known gcj problem, or 
I am missing some parameter to make it work.

Thanks!

**** The problem: *****

The actual program I am working on is too big to post here, but I 
have made a very simple test case with two classes, Test and TestB:


public class Test
{

public static void main(String args[])
{
  TestB t=new TestB();
  t.hi();
}
}

*

public class TestB
{

public void hi()
{
System.out.println("Yes!");
}
}

*
I compile them like this
gcj -shared -I. TestB.java -o TestB.dll
gcj -I. Test.java TestB.dll --main=Test -o Test.exe

Compilation gives this info/warning:
Info: resolving TestB::class$      by linking to __imp___ZN5TestB6class$E (auto
import)

If I run the Test.exe program, I get this error (JavaCompiler 0.7)
Exception in thread "main" java.lang.NoClassDefFoundError: TestB
    at 0x562408(Unknown Source)

For JavaCompiler 0.8:
Exception in thread "main" java.lang.NoClassDefFoundError: TestB
    at java.lang.Class.initializeClass(Test.exe)
Caused by: java.lang.NullPointerException
