    simple snake game under linux

    hello all, I've been looking for a simple snake game for linux in c code.
    I couldn't find anything. All I found was written for windows that contains graphics.h or any other windows library. Have any of you ever written such a game for linux?
    I would really appreciate if you'd give me a sample code or a webpage where it is.
    I don't know how to write it myself because don't know what library i should use to manipulate the snake with arrows.
    Thank you very much for your time

    Well I'm sure you could write a very simple snake game using the ncurses library.

    It might come as a shock to you, but there isn't a "snake" library.
    If you have any library capable of reading the keyboard, and any other (possibly even the same) library for drawing images on screen, then you can combine the two with a snake game.

    For example, take the ncurses approach, draw a "wall" around the edge of the screen and place a "@" in the middle of the screen.
    Move it around in response to you pressing arrow keys, and print "you're dead" if you run into a wall.
    That much alone will keep you busy for a few days, and teach you a lot about what to do next.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    Another option to consider is openGL, which might be easier to learn to use in 2D than trying to do the same thing with ncurses. OpenGL is cross-platform and well supported under linux; you'll find plenty of information, tutorials, etc. if you google. It requires the use of an additional library to provide a system and user interface. Glut and SDL are two such toolkits.
    C programming resources:
    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
    3 (different) GNU debugger tutorials: #1 -- #2 -- #3
    cpwiki -- our wiki on sourceforge

    Thank you very much for your quick response, i've already installed libncurses5-dev and i am going to study it

    Instead of using a text-based library and then combining different other libs for keyboard input and graphics based on the text including window creation, wouldn't it just be easier to use a library like Allegro or SDL or OpenGL

    I've used OpenGL and SDL on Ubuntu, Scientific Linux, and Fedora. I highly recommend that combo (SDL and OpenGL). The GLUT library is also user friendly, but I found it introduced artifacts in the program's actual performance.

    Someone here recommended SDL and I've been using it in conjunction with OpenGL since.
