Hi, I'm trying to implement a java interface using c++ code,
(with the ultimate aim to do a callback from java to calling c++).
While trying, I stumbled on a full-bug-report-request
from gcj, see below. I'd be happy to enter it in
bugzilla if this issue is unknown.
Apart from the report-request, is what I'm trying supported?
How should it be done? If cni doesn't work would jni?
Here's what I did:
===========================================
[mirleau@astrid JavaFromCpp]$ gcc --version
gcc (GCC) 4.1.0 20060304 (Red Hat 4.1.0-3)
[mirleau@astrid JavaFromCpp]$ cat JavaInterface.java
public interface JavaInterface
{
public void doIt();
}
[mirleau@astrid JavaFromCpp]$ cat gcjmain.cc
// Generic main copied from the gcj manual example
#include <gcj/cni.h>
#include <java/lang/System.h>
#include <java/lang/Throwable.h>
#include <java/io/PrintStream.h>
void myMain();
int main(int aNumberOfArguments, char* anArgumentVector)
{
using namespace java::lang;
try
{
JvCreateJavaVM(NULL);
JvAttachCurrentThread(NULL, NULL);
JvInitClass(&System::class$);
myMain();
JvDetachCurrentThread();
}
catch (Throwable* aThrowable)
{
System::err->println(JvNewStringLatin1("Unhandled Java exception:"));
aThrowable->printStackTrace();
}
}
[mirleau@astrid JavaFromCpp]$ cat JavaInterface.cc
#include "gcjmain.cc" // generic main
#include "JavaInterface.h" // generated by gcjh
#include <stdio.h>
class CppClass : public JavaInterface
