Hi,
I just started (back) the SDL. It is not too hard because I did a bit of it in
C++, but when I arrived to the initialisation and other stuff, I have messages
like this:

Error 42: Symbol Undefined _SDL_Init

Of course it is a linker error: the progrem itself compile. However, I addes all the file that (I think) would be necessery.

It is sticking on that part of code (there will probably be more later):

if (SDL_Init(SDL_INIT_VIDEO | SDL_INIT_AUDIO) < 0 )
{
throw new Error("Couldn't initialize SDL");
}

It is the way that is in the test file... it's probably the good one...

Thanks for yours answer.

Are you on windows/linux?

What SDL D interface do you use? Are you using derelict (www.dsource.org/projects/derelict) or another one?

If you're using derelict, linking isn't necessary since the library is loaded at run time. just call DerelictSDL_Load();

If not, on linux i know you can link using -lSDL. I'm not too sure about linking dll's on windows i've never done that.

I was (tryed) using the update of the DedicateD SDL port, but I will see Derelict... it sounds good. I will try it and see if it works.

I tried with Derelict, but the same problem happens.
Is there something particular that need to be done? I have the .lib in the lib
folder, the SDL.dll, and .d files... does someone know why I have this problem?
(I am sure someone got it before...)

Are you perfectly sure you're linking your project against derelictSDL.lib ? :]

Could you be using a Microsoft-format .lib? Microsoft .libs are incompatible with the Digital Mars linker.

Are you using Derelict? I thought Derelict doesn't use .libs: ("Take a look at my project 'Derelict' here on dsource. It was created to make it easier to use SDL and others, and you don't need to worry about SDL.lib.").

Problem fixed, thank a lot J C Calvarese.
Derelict is really practice, and I will recommand it to everyone!
Hehe
I will use it. And probably then when I will do some OpenGL, I will use that
too.

If you need any help, I am there... (It is just for the formality ; I could not really do anything I think...)

Thanks.
