How to Install Open Source Routing Machine (OSRM) on nixOS Latest

Open Source Routing Machine (OSRM) is a fast routing engine for use with OpenStreetMap data. It is designed to be used as a standalone routing engine or as a library for C++, Python, or JavaScript applications. Here's a step-by-step guide on how to install OSRM on nixOS Latest.

Prerequisites

Make sure you have the following installed on your system:

  • Git
  • CMake
  • GCC
  • Boost

You can install these using the following command:

sudo apt-get install git cmake gcc g++ libboost-all-dev

Step 1: Clone the OSRM repository

The first step is to clone the OSRM repository from Github. Open your terminal and run the following command:

git clone https://github.com/Project-OSRM/osrm-backend.git

This will create a directory called osrm-backend in your current working directory.

Step 2: Build the OSRM engine

Next, you need to build the OSRM engine. Navigate to the osrm-backend directory using the command line:

cd osrm-backend

Then, create a build directory and change into it:

mkdir -p build
cd build

Now you can run CMake to generate the build files:

cmake ..

After CMake has finished, use Make to build the OSRM engine:

make

This will take a few minutes to complete.

Step 3: Download OpenStreetMap data

To use OSRM, you will need to download OpenStreetMap (OSM) data for the area that you want to use it in. You can use the following command to download OSM data for your area:

wget http://download.geofabrik.de/your-country-latest.osm.pbf

Replace your-country with the country you are interested in. This will download OSM data in PBF format.

Step 4: Preprocess the OSM data

After you have downloaded the OSM data, you need to preprocess it using OSRM's osrm-extract and osrm-contract tools. Run the following commands:

./osrm-extract -p ../profiles/car.lua your-country-latest.osm.pbf
./osrm-contract your-country-latest.osrm

This will create a fully preprocessed OSRM dataset that you can use for routing.

Step 5: Start the OSRM server

You're almost there! To use OSRM, you need to start the server. Run the following command to start the OSRM server:

./osrm-routed --algorithm mld your-country-latest.osrm

This will start the OSRM server and make it available at http://localhost:5000.

Congratulations, you have successfully installed OSRM on nixOS Latest! You can now use it to generate fast, accurate routes for your applications.
