Re: [Boost-users] Multiple definition error with boost::icl

Hi Rajalakshmi, 2012/3/23, Rajalakshmi Iyer :

Hello,

I have the following code structure:

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

#include #include

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__ [...] 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&)' [...]

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

thank you for sending in this report. It is a problem in the adapter code in boost/icl/gregorian.hpp. For operators ++ and -- that are implemented for gregorian::date the keyword 'inline' is missing :( The same problem exitsts for boost/icl/ptime. Either you provide the missing keyword yourself in your boost version or you apply the patchfiles attached. I'll fix the issue in the boost trunk.
