sugoku

Simple sudoku solver using backtracking w/ a neat GUI to better display the algorithm's inner-workings.

Requirements

Our GUI uses go-sdl2 which in turn relies on the following:

• SDL2
• SDL2_image (optional)
• SDL2_mixer (optional)
• SDL2_ttf (optional)
• SDL2_gfx (optional)

Below is some commands that can be used to install the required packages in some Linux distributions. Some older versions of the distributions such as Ubuntu 13.10 may also be used but it may miss an optional package such as libsdl2-ttf-dev on Ubuntu 13.10's case which is available in Ubuntu 14.04.

On Ubuntu 14.04 and above, type:
apt install libsdl2{,-image,-mixer,-ttf,-gfx}-dev

On Fedora 25 and above, type:
yum install SDL2{,_image,_mixer,_ttf,_gfx}-devel

On Arch Linux, type:
pacman -S sdl2{,_image,_mixer,_ttf,_gfx}

On Gentoo, type:
emerge -av libsdl2 sdl2-{image,mixer,ttf,gfx}

On macOS, install SDL2 via Homebrew like so:
brew install sdl2{,_image,_mixer,_ttf,_gfx} pkg-config

On Windows,

1. Install mingw-w64 from Mingw-builds
   • Version: latest (at time of writing 6.3.0)
   • Architecture: x86_64
   • Threads: win32
   • Exception: seh
   • Build revision: 1
   • Destination Folder: Select a folder that your Windows user owns
2. Install SDL2 http://libsdl.org/download-2.0.php
   • Extract the SDL2 folder from the archive using a tool like 7zip
   • Inside the folder, copy the i686-w64-mingw32 and/or x86_64-w64-mingw32 depending on the architecture you chose into your mingw-w64 folder e.g. C:\Program Files\mingw-w64\x86_64-6.3.0-win32-seh-rt_v5-rev1\mingw64
3. Setup Path environment variable
   • Put your mingw-w64 binaries location into your system Path environment variable. e.g. C:\Program Files\mingw-w64\x86_64-6.3.0-win32-seh-rt_v5-rev1\mingw64\bin and C:\Program Files\mingw-w64\x86_64-6.3.0-win32-seh-rt_v5-rev1\mingw64\x86_64-w64-mingw32\bin
4. Open up a terminal such as Git Bash and run go get -v github.com/veandco/go-sdl2/sdl.
5. (Optional) You can repeat Step 2 for SDL_image, SDL_mixer, SDL_ttf
   • NOTE: pre-build the libraries for faster compilation by running go install github.com/veandco/go-sdl2/{sdl,img,mix,ttf}

• Or you can install SDL2 via Msys2 like so: pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-SDL2{,_image,_mixer,_ttf,_gfx}
