Sorry, apparently this is an issue with my file naming convention

[Nicholas-Kastanos]

When I was compiling SUMO, I did not define the ACCEPT_USE_OF_DEPRECATED_PROJ_API_H CPP macro

Hi,
I'm encountering a similar issue in tutorial 6. Would you be able to tell me how you solved it @Nicholas-Kastanos ? Thanks in advance!

[Nicholas-Kastanos]

@rohanpaleja27 I defined the macro mentioned above during compilation of SUMO. Unfortunately it was long ago and cannot remember more details.
