Re: [Swig-user] swig-4.0.0 beta1 test available

[Seth G <se...@ge...>]

Hi William,

Thanks for the reply. 
The output of ``swig -python -E ../mapscript.i`` is here:

https://gist.githubusercontent.com/geographika/504859a6f08c8152d17f33d4e6a7c402/raw/a26a775ced4994d040b249c7ca77918ff1be70ea/swig_preprocessor.c

I don't think any Python options are set for the SWIG command. The process is run via CMake as part of a larger build process, but I think the only flag CMake sets on SWIG is -py3 when building with Python3. 

CMake file: https://github.com/mapserver/mapserver/blob/branch-7-4/mapscript/python/CMakeLists.txt

Generated mapscriptPYTHON_wrap.c - https://gist.githubusercontent.com/geographika/0c1bd5532620aec2d7c79792c09eeaa3/raw/5048916b0d7987d1cf9848f2cf7c7eda89afca3b/mapscriptPYTHON_wrap.c

Build output - this includes the full MapServer CMake build output - the Python SWIGbindings output is at the end:

https://gist.github.com/geographika/72fd1dec763aa01d38f7c4d515968225

Hopefully the above is of some help. Let me know if I can do anything else. 

Regards,

Seth
