    Any code example to compile and link? On a wild guess, do you have a global main function?

    Are you still having trouble with SDL? You have to add:
    Code:
    int main( int argc, char* args[] ) 
    {
    }

    First, stop bumping with multiple posts. Second, we have no clue where you put your files, what your linking, or anything of that nature, so we can't help you. Thirdly, I think you should practice doing console programs before doing anything with graphics, your knowledge seems limited.

    ok im sorry if i offend people by posting alot with little knowledge about what im posting
    if i new what information you needed i probly would also then know the anwser to my question
    i have always tried to learn things by adapting other peoples codes to see what happens by means of trial and error and reading tutorials i gradually expand my knowledge but because i dont understand this sytem very well and cant get the compiler to compile the programs i downloaded i cant use trial and error or any thing for that matter as i cant evan test to see if my code is working
    if i wrote the program myself i may have been able to answer your questions to help you help me but i didnt so please look on the link i sent and download the sourse file because its not my code i dont want to post it as i dont want people to think that i may have either wrote it or stolen it .
    ps in not up to date with forum etiqute and for this i am sorry

    If you have a problem with your compiler and nothing helps, download a new one.

    For example, Dev-C++: http://www.bloodshed.net/dev/devcpp.html

    He said he had that. He downloaded the MSVC Express Edition so he can easily install SDL. But apparently he still can't figure it out. I gave him the tutorials at lazyfooproductions.com and he still can't install it. I'm not sure what's so hard about it...

    well the thing is i started with devcpp but i couldnt get sdl to work in there either for some reason so i spent the whole of last night downlading the microsoft visual express compiler as recomended but still cant get it to work in there im not sure if its the file imtrying to compile or my compiler isnt set up correctly im not entirely sure as to what a linker is but i would guess that it holds the address of where the files it needs are located .
    i have looked at several tutorials on how to set up sdl on both dev and visual but for some strange reason its just not working so obvioulsy im doing something wrong but i just dont know what.
    aslo i used tutorial from game dev site
    i think it might be because im using sombody elses code who may have set there sdl up differently to the way i have seen to do it.
    sentral i dont mean to sound like a complete noob.
    as u have the same version of compiler i have maybe you could tell me where u save the sdl include sdl libs and sdl header files and also maybe what u write in the relavant linker box that way it is sure to work

    SDL works for me with Dev-C++.
