Compiling and Running

Compiling

To compile the project, first, create a build directory and change to that directory:

mkdir build && cd build

From within the build directory, then run cmake and make as follows:

cmake ..
make

Running

The executable will be placed in the build directory. From within build, you can run the project as follows:

./OSM_A_star_search

Or to specify a map file:

./OSM_A_star_search -f ../<your_osm_file.osm>

Testing

The testing executable is also placed in the build directory. From within build, you can run the unit tests as follows:

./test
