error building Quantlib SWIG 1.34

I am getting this error when I try to make python wrapper - successfully ./configure; python Python/setup.py wrap

Thanks for posting! It might take a while before we look at your issue, so don't worry if there seems to be no feedback. We'll get to it.

What version of QuantLib (the C++ library) do you have?

(Also, you probably know this already, but if you don't need to modify the wrappers you can use pip install QuantLib to get precompiled wrappers.)

Quantlib 1.34

• had to modify the wrapper as i made some changes to fittedbonddiscountcurve constructor

Ok, I had a look - if you can upgrade to Boost 1.69 or above, it should fix the problem. If you can't, you'll have to edit ql/math/integrals/expsinhintegral.hpp after the #else and add the missing method; it can throw an exception like the others.

Thanks Luigi! That worked!
