Compilation problem with g++ 4.8.2

[Dagur Gunnarsson]

Hello,

 

Is anyone having problems compiling (on linux) a quantlib project using gcc version 4.8.2 ??

I am getting

 

In file included from /usr/include/ql/indexes/inflationindex.hpp:29:0,
                 from /usr/include/ql/cashflows/yoyinflationcoupon.hpp:28,
                 from /usr/include/ql/cashflows/capflooredinflationcoupon.hpp:27,
                 from /usr/include/ql/cashflows/all.hpp:6,
                 from /usr/include/ql/quantlib.hpp:40,
                 from /home/dagur/work/xxx.cpp:1:
/usr/include/ql/termstructures/inflationtermstructure.hpp: In member function ‘bool QuantLib::InflationTermStructure::hasSeasonality() const’:
/usr/include/ql/termstructures/inflationtermstructure.hpp:295:16: error: cannot convert ‘const boost::shared_ptr<QuantLib::Seasonality>’ to ‘bool’ in return
         return seasonality_;

 

The same code compiles fine with gcc 4.7.2 on Fedora 18 64bit

 

regards

Dagur

Hello,
    gcc 4.8 is probably in C++11 mode and has rejected the implicit
cast to bool.
Try replacing the offending line with

    return static_cast<bool>(seasonality_);

instead. (The fix is in the git repository already, but it hasn't made
its way into a release yet.)
