I am using swig 2.0.7 on Hp-ux to wrap our C++ libraries. There are no errors until attempting to run when a crash occurs.
Using:
HP-UX bob B.11.23 U ia64 0835920252 unlimited-user license
aCC: HP C/aC++ B3910B A.06.20 [May 13 2008]
java version "1.7.0.01"
Java(TM) SE Runtime Environment (build 1.7.0.01-jinteg_2012_05_10_04_39-b00)
Java HotSpot(TM) Server VM (build 22.1-b02-jre1.7.0.01-rc2, mixed mode)
the swig command is
swig -c++ -package com.mybuild -java -I../Library -I../../Common mybuild.i
the swig interface file
/* File : mybuild.i */
%module mybuild
%include "std_string.i"
%{
#include "mybuild.h"
%}
%include "mybuild.h"
On building, I see one warning
warning #2177-D: function
"SWIG_JavaThrowException" was declared but never referenced
static void SWIGUNUSED SWIG_JavaThrowException(JNIEnv *jenv, SWIG_JavaExceptionCodes code, const char *msg) {
Trouble occurs when I run, a crash occurs and I get

Using gdb, I received a little more info:

My theory is that I need to tweak Swig to stop this crash. Assistance would be appreciated.
Edit Code added
Sorry about that, took me a while to zero in on what may be causing problem. I found that this will cause a crash
#include <iostream>
#include <string>
using namespace std;
static const string rangeFieldString("RangeField");
int main()
{
cout << "I sure hope this works" << endl;
return 0;
}
but this will not
#include <iostream>
#include <string>
using namespace std;
static const char* rangeFieldString("RangeField");
int main()
{
cout << "I sure hope this works" << endl;
return 0;
}
I found the solution to this. When building on the system, by adding -mt to CFLAGS and LDFLAGS, the problem was solved
