[Quantlib-dev] Compilation error: ‘constexpr’ needed for in-class initialization of static data member

[Francois B. <ig...@gm...>]

Hi,

When I try to compile the current head on master branch on Linux with
gcc 6.3.1 20161221, I get this error:

../../ql/cashflows/lineartsrpricer.hpp:66:47: error: ‘constexpr’ needed for
in-class initialization of static data member ‘const Real
QuantLib::LinearTsrPricer::defaultUpperBound’ of non-integral type
[-fpermissive]
                           defaultUpperBound = 2.0000;

The same for the lower bound.

I suspect it's some kind of C++11 issue. Should I change my compiler or
change something the 'const' to 'constexpr' in the .hpp file?

thanks,
Francois Botha
