Python SWIG and QL_ENABLE_SESSIONS

suhasg

I have uncommented # define QL_ENABLE_SESSIONS in userconfig.hpp file and successfully rebuilt QuantLib library.

Then I modified swap.i file to add a fixedLeg method that returns a Leg.

Then I successfully executed “python setup.py wrap” call.

I got below errors when I tried “python setup.py build” call.

Did I miss anything? Do I need to insert sessionId() method in any of the QuantLib classes ?

 

Thank you.

Re: Python SWIG and QL_ENABLE_SESSIONS

Luigi Ballabio
Hi,
    apologies for the delay, I was on vacation.
Yes, you have to define a sessionId() function (not a method) and link
it in the Python module together with the library. (If you define
QL_ENABLE_SESSIONS, this is required whether or not you modify the
wrapper).
