Hello,

I have the following code structure:

Range.h:
------------
#ifndef __RANGE_H__
#define __RANGE_H__

#include <boost/icl/interval_map.hpp>
#include <boost/icl/gregorian.hpp>

using namespace boost::gregorian;
using namespace boost::icl;

class Range
{
public:
        Range() ;
        ~Range() ;

private:
       interval_map< date, int > m_mapRange
};

#endif // __CAMPAIGNS_BY_RANGE_H__

Range.cpp
----------------
#include "Range.h"

Range::Range() {

}

Range::~Range() {

}

main.cpp
--------------
#include "Range.h"
int main() {
    return 0;
}

When I build this code, I see the following errors:

main.o: In function `boost::icl::operator++(boost::gregorian::date&)':
main.cpp:(.text+0x0): multiple definition of `boost::icl::operator++(boost::gregorian::date&)'

collect2: ld returned 1 exit status
make: *** [rangetest] Error 1

Any ideas on how to resolve this would be greatly appreciated.

Thanks!
