Is there a Python package available?

Swig wrapper compiling not working. I tried on Win10 and Mac 10.15. Has anyone succeeded in getting this to work in Python?

I think I might have fixed the issue w/ Swig 4.0.2 compatibility. Give it a try? Some pull requests for better testing would be appreciated... :)

Thank you for the fast fix but I think my problem is specific.

I am using Python 3.8 and the python setup.py install succeed to launch SWIG but SWIG craps out! Maybe a bad C++ compiler or unable to read the rs_base file in certain lines/

OK, I've removed the #warning pre-processor directive that Visual Studio seems to be having trouble with...

Thank you for being so responsive! I am getting warmer now. Still failing at setup with this error now:

So apparently, file ezcod needs a line in header

#define _USE_MATH_DEFINES

as per this https://stackoverflow.com/questions/26065359/m-pi-flagged-as-undeclared-identifier

However, Windows Visual studio still craps out when compiling. I am not sure where the log file is to attach but theres a long dump of warnings. Then, there is the followoing errors below. I guess the platform for Windows VC tools has changed alot and broken the compatibility of the compiler since 2 years ago.

Do you think I should try it on an Ubuntu machine and if so what version of Swig did you use successfully to compile the Python interface? Thanks
