Hi Group

I try to create JNI library wir CW 8.3 on MacOS 10.3.6.
I would prefer to do this lib in C++. So i resulted into the following
construct in cpp-file:

#define _MSL_USING_MW_C_HEADERS 1

#include <string>
using namespace std;

#ifdef __cplusplus
extern "C" {
#endif

#pragma export on
#include "RequestDispatcher.h"  // This is the machine generated header
                                  files with the JNI Header...

JNIEXPORT jstring Java_...._myfunc()
{

}

#ifdef __cplusplus
}
#endif

Now when i declare a string variable in myfunc i run into the linker error
"__ZdlPV is undefined".
I use the Project settings from the example "Advanced JIN example".

I invested a lot of time in this issue and i spin round.
I have a lot of questions concerning this topic:

1. Is it allowed to set the first ##define statement? (without this
statement i cannot compile it.)

2. how can i avoid this linker error? What i'm doing wrong?
3. i had to change on checkbox in the linker settings: i disabled the "Two
level Namespaces".
I had to do that, because when i tried only to integrate a strcpy() cmd i
had some other link errors. With this checkbox disabled it worked.

But now i'm tumbeling from one problem to another and i'm not sure if i
really had solved the problems before or if i created some new one.

Any help is really most welcome, bacause i have no more idea how to solve
this...
