• cmake >= 3.11.3
  • All OSes: click here for installation instructions
• make >= 4.1 (Linux, Mac), 3.81 (Windows)
  • Linux: make is installed by default on most Linux distros
  • Mac: install Xcode command line tools to get make
  • Windows: Click here for installation instructions
• gcc/g++ >= 7.4.0
  • Linux: gcc / g++ is installed by default on most Linux distros
  • Mac: same instructions as make - install Xcode command line tools
  • Windows: recommend using MinGW
• IO2D
  • Installation instructions for all operating systems can be found here
  • This library must be built in a place where CMake find_package will be able to find it

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

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>

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

./test

• 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.
