Quantlib 1.14 and Quantlib1.14-SWIG: versions of V

Question

I downloaded tarbals for both quantlib 1.14 and quantlib 1.14-swig. The quantlib folder under SWIG does contain the quantlib_wrap.cpp. But the setup complains the the MSC version. Here is the new error. This post is associated with another post on missing quantlib_wrap.cpp error message.

C:\Users\Public\3rdParty\Libraries\QuantLib-1.14\ql/config.msvc.hpp(29) : fatal error C1189: #error :  "versions of Visual C++ prior to VC++10 (2010) are no longer supported"

Use 1.13. VC9 is no longer supported. – Luigi Ballabio

I will try 1.13 also. But actually, I do have VC++ 14.0 installed. I am using VS2015 to compile the quantlib. Not sure the true reason.

I did try the 1.13 and run into linking error. I think it might be from the inconsistency between the compile of quantlib-swig (VC9.0) and quantlib(VC14). If that is the case, how do we control the compiling version of quantlib-swig? Is there an option to control that?

I'm guessing you're compiling the module for Python 2.7?

Python 2.7 for Windows is compiled with VC++ 2008 and uses it for compiling external modules as well. If you can switch to Python 3.5 or later instead, it will use your VC++ 2015 installation.
