Cloning

When cloning this project, be sure to use the --recurse-submodules flag. Using HTTPS:

or with SSH:

git clone git@github.com:udacity/CppND-Route-Planning-Project.git --recurse-submodules

Dependencies for Running Locally

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

Troubleshooting

  • Some students have reported issues in cmake to find io2d packages, make sure you have downloaded this.

  • For MAC Users cmake issues: Comment these lines from CMakeLists.txt under P0267_RefImpl

    if( NOT DEFINED IO2D_WITHOUT_SAMPLES )
         add_subdirectory(P0267_RefImpl/Samples)
    endif()
    

    And then run "ALL_Build" and "install" in XCode.

    If any packages are missing try to install packages using

    brew install pkg-config
    
  • For Ubuntu Linux IO2D installation errors, follow the given steps:

     sudo apt update
     sudo apt install build-essential
     sudo apt install cmake
     sudo apt install libcairo2-dev
     sudo apt install libgraphicsmagick1-dev
     sudo apt install libpng-dev
    
     git clone --recurse-submodules https://github.com/cpp-io2d/P0267_RefImpl
     cd P0267_RefImpl
     mkdir Debug
     cd Debug
     cmake --config Debug "-DCMAKE_BUILD_TYPE=Debug" ..
     cmake --build .
     sudo make install
    
  • If you are working on windows and unable to install IO2D:

    • Enable WSL (Windows Subsystem for Linux) and use a distribution like Ubuntu.(available from the windows store):
    • Install the required dependencies (compiler, cmake etc.) in the WSL(as mentioned above for ubuntu)
    • Configure CLion to use the WSL toolchain
    • Use the WSL toolchain to build the project
    • If you are still facing errors, visit this link.
  • If you are facing errors with --config try to remove -- from the command.
