Problem using standard libraries in C++ class

Question

Hi
I am new to JNI. I am having problems using standard C++ library.
My java code looks like
public class JavaSide {
public native void sayHello();
static {
System.loadLibrary("NativeSideImpl");
public static void main(String[] args) {
JavaSide app = new JavaSide();
app.sayHello();
and My NativeSideImpl.cpp code is
#include <stdio.h>
#include "JavaSide.h"
JNIEXPORT void JNICALL Java_JavaSide_sayHello
(JNIEnv *env, jobject obj)
cout<<" Hello";
I am compiling this on solaris 5.8 using the following command
CC -G -Kpic -I/usr/java/include -I/usr/java/include/solaris NativeSideImpl.cpp -o libNativeSideImpl.so
when I run my java program using
java JavaSide
I get the following exception
Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/oracle/temp/libhello.so: ld.so.1: java: fatal: relocation error: file /home/oracle/temp/libhello.so: symbol __1cDstdEcout_: referenced symbol not found
at java.lang.ClassLoader$NativeLibrary.load(Native Method)
at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1473)
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1397)
at java.lang.Runtime.loadLibrary0(Runtime.java:788)
at java.lang.System.loadLibrary(System.java:832)
at HelloWorld.<clinit>(HelloWorld.java:6)
The program works if I replace cout with printf() .
My LD_LIBRARY_PATH does include the path where of the C++ standard libraries.
Any help would be much appreciated
Thanks in advance..

Well, cout was just a a simple example. I was having problems with using the std C++ libraries, e.g ostringstream . and likes .
I tried using the -lCstd in the compile option and it worked.
