Re: [Quantlib-users] quantlib ext::shared_ptr safety

[Jonathan S. <sw...@gm...>]

Hi Jerry,

Did you know that QuantLib is already exposed to several scripting
languages through SWIG? You can download the latest version here:
https://github.com/lballabio/QuantLib-SWIG

In terms of safety, the main thing to worry about when wrapping QuantLib in
a scripting language is the garbage collector accessing objects from
different threads. You can read more about it at [1] and also use one or
more of the available CMake variables [2] to compile in a more or less
thread safe manner.
