uSnake

The popular game of Snake, but instead written for as many platforms as possible.
Based off of MattKC's source code, this project also inherits the same license.

Requirements for running uSnake

• Windows XP (see Compiling for Windows XP below)
  • otherwise Windows 7
• macOS X Snow Leopard
  • macOS X Tiger and Leopard might be possible (using -mmacosx-version-min=10.4) however is untested.
• Linux kernel verison 2.6.0 or greater
• Haiku (beta 5)

Requirements for compiling uSnake

• Windows 10 recommended (in order to use MSYS2 MINGW64/MINGW32)
  • Compiling with Windows 8.1 and below could be possible, however that is up to you.
• Any version of macOS which can install GCC
  • Homebrew requires at least macOS Ventura, MacPorts requires at least MacOS X Leopard
• Any supported version of any Linux distribution
  • It is likely possible to compile uSnake using Debian Etch however good luck getting apt working :P

Compiling

Important

Linux: Make sure the development headers for X11 are installed:
Debian-based distributions: libx11-dev
Fedora-based distributions: libX11-devel
Arch-based distributions: libx11

MacOS: From Mountain Lion onwards, Apple no longer provides an X server by default. Please make sure you install XQuartz (and by extension the Xcode Command Line Tools) before you try to compile or run usnake.

Haiku: You will need to install the Xlib compatibility layer xlibe.

These compilation instructions assume there is no cross-compilation (i.e. you compile a Windows executable on Windows), and that you are using the GNU Compiler Collection (GCC)
(although in most cases you can compile with Clang too, in which case you can just change gcc to clang).

Compiling for Linux (and Haiku)

It is pretty easy to compile usnake. In fact, it can be done immediately (as long as all prerequisites are met, read the note above for more info):
gcc -g usnake.c -o usnake -lX11

Compiling for Windows

First, make sure you have MSYS2 installed and updated.
Then, make sure that the correct MinGW toolchain is installed:

$ pacman -S mingw-w64-x86_64-toolchain to compile for 64-bit Windows
$ pacman -S mingw-w64-i386-toolchain to compile for 32-bit Windows

Compiling for Windows 7 and above

Replace '##' with either 32 or 64 depending on the target architecture:
C:\msys64\mingw##\bin\gcc -g usnake.c -o usnake-gcc-win## -lgdi32 -luser32

Compiling for Windows XP

Replace '##' with either 32 or 64 depending on the target architecture:
C:\msys64\mingw##\bin\gcc -g usnake.c -o usnake-gcc-win## -lgdi32 -luser32 -D_WIN32_WINNT=0x0501

Compiling for macOS

For some reason, gcc on macOS fails using the standard Linux command unless you manually specify the X11 include and lib directories.
Replace path/to with the folder in which X11/include and X11/lib can be found (usually usr or opt):
/usr/bin/gcc -g usnake.c -o usnake-gcc -lX11 -I /path/to/X11/include -L /path/to/X11/lib/
