Subject: Using libraries - CNI and JNI
Date: Sat, 12 Apr 2014 09:37:00 -0000 [thread overview]
Message-ID: <5349091B.9080006@email.cz> (raw)
Hello guys,
I have some questions about GCJ:
1. Is it possible to compile and get work together main programme and
.so library (both written in Java) with GCJ using CNI or JNI?
2. I have the following code:
public class Test {
static {
System.loadLibrary("Test");
}
public native void hello();
public static void main(String[] args) {
new Test().hello();
}
}
I tried to compile it with "gcj Test.java --main=Test -o Test.bin". I got:
/tmp/ccWZkOjd.o:(.data+0x50): undefined reference to `hidden alias for
void Test::hello()'
/tmp/ccWZkOjd.o:(.data+0xc8): undefined reference to `hidden alias for
void Test::hello()'
I did not use "-fjni" so CNI should have been set. Where is the problem,
please? Thank you.
