    C and SDL for a beginner

    Hi,

    I have been programming in C for a while now as an Mech eng student, so its all been calculations and stuff up to now, but I have recently wanted to be able to add basic graphics. I have installed FINALLY after a lot of hell the SDL libraries and it all works in Codeblocks - the editor i am using.

    I am struggling to find a way to draw to the screen for instance just a box around Hello World! would get me on my way, the graphics dont need to be animated, but i cant find a decent tutorial for C anywhere. Please can someone help me with a basic tamplate c file that will draw a box say 2 pixels thick around a printf statement, just to get it to look a bit nicer.

    P.S is C dieing out because everytime i do a search for C SDL tutorials, they seem to all really be in C++???

    Thanks

    searching for c anything is hard because it's a bad keyword. c++ gives more results and a lot of c++ stuff can be used or translated to c without a problem. c isn't dying out, it's still going strong. the c++ cabal just wants you to think it is so you'll join the dark side.

    google for "simple SDL example" gives this:
    http://friedspace.com/SDLTest.c

    I don't know if that's helpful or not.

    It looks like perfectly valid C to me.

    I get maybe two dozen requests for help with some sort of programming or design problem every day. Most have more sense than to send me hundreds of lines of code. If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    Not only do I agree, but "gcc -Wall -Wextra -ansi -pedantic sdl.c" compiles fine - which means that gcc thinks it's ANSI C too. [ok, two warnings for argc and argv not being used - but that's not a "this is not ANSI" warnings].

    I've never heard of SDL before, but if it can do graphics and sound, I am interested.

    I am going to install SDL, but can you tell me what problems you had with that?

    Thanks in advance.

    EDIT: I am using Win XP
    OS: Linux Mint 13(Maya) LTS 64 bit.

    Basically (also using xp) i installed codeblocks with mingw and then followed this tutorial for SDL:

    http://lazyfoo.net/SDL_tutorials/lesson01/index.php

    the rest of the tutorials are for c++ but that one is very good.

    its not too bad SDL been having a look
