Error Compiling QuantlibXL 1.3.0 in Visual Studio 2012

[Ali Hassani]

Hello,

I am trying to compile QuantlibXL 1.3.0 in Visual Studio 2012.  I am getting the following error:

3>------ Build started: Project: QuantLibObjects, Configuration: Release (static runtime) Win32 ------
3>  interpolation.cpp
3>qlo\interpolation.cpp(77): error C2664: 'std::make_pair' : cannot convert parameter 1 from 'const double' to 'QuantLib::Real &&'
3>          Conversion loses qualifiers

Can somebody lend any insights into this?

Thanks,

Ali

Actually it compiles if I change this:

pairs[i] = std::make_pair<Real, Handle<Quote> >(x[i], yh[i]);

to this:

pairs[i] = std::make_pair(x[i], yh[i]);

apparently there's been some change in Visual C++ 11 where I guess you aren't supposed to explicitly specify the datatypes in make_pair?

As far as I know, with std::make_pair you were never supposed to explicitly specify the datatypes. In fact, that’s exactly the point of using std::make_pair instead of calling the std::pair constructors directly: constructors require that you specify the types, functions resolve them automatically.

I am not sure whether the C++ standard allows for specifying the types explicitly, but the recommended syntax is and has always been without types.

Yes, the point of make_pair is to call it without specifying the types. It shouldn't hurt, though. The error might have to do with the changes to support C++11 (seeing as a right-value reference type is mentioned in the error message).

Anyway, I'll change it in the repository.
