Hello,

I have just built osrm-routed from source and I want to work on the Python bindings. When I try to build, I am encountering the following:

What is the best way to resolve this? Thanks!

Which OSRM version are you trying to compile against? I haven't tested this project in over a year - worst case they introduced breaking API changes.

I am testing 5.22 (the latest release). 5.4 seems to be nearly 3 years out of date at this point unfortunately, so you are probably correct.

Looks like this commit broke the libosrm API by changing its public interface
