Latest SUMO fails to build on Windows when setting CS_ENABLE_BINDINGS to true

[bran-jnw]

Getting:

Syntax error in input(1) at line 572 in libsumo_typemap.i, which is the line
SELF_NULL_CHECKER(TraCIPosition)

Have tried commenting out the line but then it just moves on to the next one.
Compiles without issue when building just Java and python bindings.

Full error message here:

Works by commenting out all SELF_NULL_CHECKER, assume that the function definition is missing for C#, but not sure how to fix it.

@bran-jnw Thanks for reporting! It would be great if you can check whether the new code works.

[bran-jnw]

@behrisch Works fine now, thanks! And thanks for adding getIncoming/OutgoingEdges to Junctions in libsumo at some point, made my life easier (had to add that myself before).

[behrisch]

@bran-jnw Since you seem to use this actively. Would you mind writing up a small "tutorial" how to use it similar to what is there for Java and Python for instance (https://sumo.dlr.de/docs/Libsumo.html or https://sumo.dlr.de/docs/Libtraci.html)? Thanks a lot in advance! If we can build a test after the tutorial we would also consider enabling it by default and releasing it.

[bran-jnw]

@behrisch I could do that, would be great if C# bindings would be included as default! How do I go about actually adding to the documentation?

[bran-jnw]

@behrisch Would it also be possible to add this (or similar namespace) to the SWIG settings?
set(CMAKE_SWIG_FLAGS -namespace Libsumo)
