osrm-c

C-wrapper to the Open Source Routing Machine - OSRM.

Why?

I wanted a fast Python binding for the library (check example/). And I also think it's cool to have julia/rust/go bindings (and a c-wrapper would just make those real-easy).

Build

Building osrm-c requires osrm to be installed, and all dependencies required for building osrm, plus scons for building.

For how to build/install osrm, check osrm's wiki page.

git clone https://github.com/tdihp/osrm-c.git && cd osrm-c
scons
# scons install

Alternatively, you can just grab osrm_c.cpp and do whatever convenient.

Versioning and Compatibility

Each release of osrm-c will be able to compile against at least ONE RELEASE of osrm-backend. See CHANGELOG.md for release information.

However osrm-c.h shall remain backward-compatible, unless noted otherwise in CHANGELOG.md.

Vagrant

To aid development and testing of this wrapper, I've provided vagrant config.

However, when using windows host, symlink won't work.

Use the following fix before running scons:

mkdir -p /vagrant/build
sudo mount -t tmpfs -o size=1G tmpfs /vagrant/build
sudo chown vagrant:vagrant /vagrant/build
