Hi,
The osrm-contract command is used to create the hierarchy for the CH
algorithm. You need to use the MLD pipeline[1] to preprocess the data.
Alternatively, you can change the algorithm used in example.cpp here[2].
HTH,
Julien

I figured that the data have to be pre-processed to fit the algorithm
MLD. I was wondering how to do that? What I did is building from the
source to get this osrm-* binaries, and then using osrm-extract and
osem-contract commands to preprocess the .osm.pbf file. After building
osrm-example using Cmake, run the command ./osrm-example. Did I miss
something?
Any comments are greatly appreciated.
