Package: libboost-dev
Version: 1.33.1-4
The compiler accuses a multiple definition error during linking.
multiple definition of
`_ZN5boost7numeric5ublas21scalar_divides_assignIT_T0_E8computedE'
Here is a simple example using 3 files: CommonClass.h, CommonClass.cpp
main.cpp
//******* CommonClass.h **********
#ifndef COMMONCLASS_H_
#define COMMONCLASS_H_
#include <boost/numeric/ublas/vector.hpp>
typedef boost::numeric::ublas::vector<double> boost_vector;
class CommonClass
{
public:
CommonClass();
virtual ~CommonClass();
};
#endif /*COMMONCLASS_H_*/
//******* CommonClass.cpp **********
#include "CommonClass.h"
CommonClass::CommonClass()
{
}
CommonClass::~CommonClass()
{
}
//******* main.cpp **********
#include <iostream>
#include "CommonClass.h"
using namespace std;
int main(void) {
cout << "Hello World!" << endl;
return 0;
}
The Linker output:

Build complete for project test_boost
Using the stable version of the boost libraries I got no errors.
I'm running debian testing with the eclipse IDE, GCC 4.1.1-5
Please let me know what other type of info would be helpful.
