Devc++ "all In One" Does Not A Lot?

[acron^]

Ok, so I'm absolutely rubbish at Linux and am a total VS2005 fanboi.
After failing horribly to get VS setup for .gpe compiling (yes, I tried the Wiki several times) I gave up and
tried to use the DevC++ 'starter kit' in the official SDK.

Because it's got really nice switching between win/gp2x, I can see what i'm doing as I go along. So, I start with something really simple. A few SDL functions to clear the screen to a colour and wait for an input before quitting. The 'win' version compiles, runs, tada, lovely. I compile a gp2x version, whack it onto my SD card and...black screen :/ It waits nicely for the input before quitting, but that's all it does.

I then tried taking some code from a couple of the demos here on the site. Similar ways of doing the same thing and NONE of them do anything!

Is there some special way to setup DevC++? I'm using F/ware 2.0 - would this make a difference? I just can't think what i'm doing wrong if it's supposed to be as easy as everyone suggests :s

Thanks

UPDATE:
I've just been through this entire tutorial and I get exactly the same result.

When I first got my GP2X, I installed these SDL Libraries - could that have had anything to do with it? Is there any way to default everything on my GP2X? Will upgrading the firmware acheive this?

It is hard without looking at the code. How do you initialise the SDL instance for the GP2X version.

You can grab my source for my last game to cross reference if you want:

/* Initialize SDL */
	if (SDL_Init (SDL_INIT_VIDEO | SDL_INIT_AUDIO | SDL_INIT_JOYSTICK) < 0) {
		fprintf (stderr, "Couldn't initialize SDL: %s\n", SDL_GetError ());
		exit (1);
	}
	atexit (Terminate);

	SDL_ShowCursor(SDL_DISABLE);

	/* Set 320x240 16-bits video mode */
	screen = SDL_SetVideoMode (320, 240, 16, SDL_SWSURFACE);
	if (screen == NULL) {
		fprintf (stderr, "Couldn't set 320x240x16 video mode: %s\n", SDL_GetError ());
		exit (2);
	}
	
	SDL_FillRect(screen,NULL,SDL_MapRGB(screen->format,0,255,0));

The thing is, i've taken code from other demos - like Guyfawkes for example - and it still doesn't work.
I've tried 2 different IDEs now, both with identical results. I'm starting to wonder if these 'SDL Libraries' have some how messed things up :/ But saying that, all my games and Guyfawkes pre-compiled .gpe still works fine! Argh.

Since you are using the HW libraries, try changing the following line

screen = SDL_SetVideoMode (320, 240, 16, SDL_SWSURFACE);

to

screen = SDL_SetVideoMode (320, 240, 16, SDL_HWSURFACE);

I would also check if you have the data files in the correct place. Also try compiling something you know works 100%.

I think that may have done the trick! I've certainly got CodeBlocks working now so i'll just keep my fingers crossed and hope it lasts Thanks for your help!

I use Code::Blocks too, it's such a great IDE! And using SDL_SWSURFACE with the hardware libs should give you no problems, I use it all the time when working with SDL_gfx primitives.
