Building the project

macOS/Linux

In order to successfully build the project we need a C++ compiler, CMake and also the SDL graphics libraries: SDL2, SDL2_image and SDL2_ttf.

In Debian/Ubuntu, this can be achieved by running the command:

apt-get install -y g++ cmake libsdl2-dev libsdl2-image-dev libsdl2-ttf-dev

In macOS, we can run:

brew install cmake sdl2 sdl2_image sdl2_ttf

Then we just download the code, build the project and run the program:

git clone https://github.com/fredericojordan/fast-chess.git
cd fast-chess
cmake .
make
./bin/fast-chess
