problem of tutorial example mimoconv

[flex]

I have successfully compiled itpp-3-10-12 with the release output itpp.lib.
It seems that all examples in the tutorial src works well except "mimoconv".
When I build a project of "mimoconv", there are three errors as follows:

1)error LNK2005: "class itpp::Mat<class std::complex<double> > const __cdecl itpp::operator*<class std::complex<double> >(class itpp::Mat<class std::complex<double> > const &,class itpp::Mat<class std::complex<double> > const &)" (??$?DV?$complex@N@std@@@itpp@@YA?BV?$Mat@V?$complex@N@std@@@0@ABV10@0@Z) already defined in mimoconv.obj itpp.lib

2)error LNK2005: "class itpp::Vec<class std::complex<double> > const __cdecl itpp::operator*<class std::complex<double> >(class itpp::Mat<class std::complex<double> > const &,class itpp::Vec<class std::complex<double> > const &)" (??$?DV?$complex@N@std@@@itpp@@YA?BV?$Vec@V?$complex@N@std@@@0@ABV?$Mat@V?$complex@N@std@@@0@ABV10@@Z) already defined in mimoconv.obj itpp.lib

3)fatal error LNK1169:

Why does this happen?
