Example of how to build and link against SDL?

Hi,
I’ve got a hobby game I’ve been working on with Windows. It’s all C and SDL so I’d like to try to build on RISC OS.

Can someone provide a sort of “hello world” example how how to compile/link with SDL? I have GCC and DDE, don’t mind which I use, though I’ve used a couple of #pragma that DDE doesn’t seem to like, so maybe GCC is the way to go.

Cheers

Then, I’d imagine just link with it as usual.

I’ve got a hobby game I’ve been working on with Windows. It’s all C and SDL so I’d like to try to build on RISC OS.

There’s a port of the SDL1 library (LibSDL1.2) available via PackMan.

#include <SDL/SDL.h>

int main(void) {
    int eventloop = 1;
    SDL_Event event;

    SDL_Init(SDL_INIT_VIDEO);
    SDL_WM_SetCaption("Hello World.", NULL);
    SDL_SetVideoMode(800, 600, 32, SDL_HWSURFACE);
    while (eventloop) {
        SDL_WaitEvent(&event);
        if (event.type == SDL_QUIT)
            eventloop = 0;
    }
    SDL_Quit();
    return 0;
}

Here’s a simple Makefile to compile and link the above example on RISC OS using GCC.

CC      = gcc -static
CFLAGS  = -O3 -Wall -ISDL:
LDFLAGS = -LSDL: -lSDL

helloworld: helloworld.c
	$(CC) $(CFLAGS) -o helloworld helloworld.c $(LDFLAGS)

clean:
	rm -f helloworld

Thank you Chris, this looks like exactly what I need. It never occurred to me to use make, I was planning to just have an Obey file with lots of lines in it, but this looks perfect for me.

Chris, thanks again for this, I wasn’t able to build statically for the moment as libFLAC in Packman doesn’t seem to have a static library in there, but it works great for building against the shared libraries, and my little game attempt now runs on RISC OS!
