After some trouble with main, SDL_main, _main, and _SDL_main, I managed
to link and run my application.

It links and runs, but dies with this error:

First-chance exception in minion.exe (SDL.DLL): 0xC0000005: Access

Violation.

It is loading the SDL.dll, I can see that. In fact, it passes SDL_Init
but fails in SDL_SetVideoMode: pSurface is null.

// Initialize SDL
if	(SDL_Init(SDL_INIT_VIDEO) < 0)
{
    std::cerr << "Couldn't init SDL: " << SDL_GetError() <<

std::endl;
exit(1);
}

// Set SDL video mode
pSurface = SDL_SetVideoMode(640, 480, 16, 0);
if (pSurface == null)
{
    std::cerr << "Couldn't set video mode: " << SDL_GetError() <<

std::endl;
exit(1);
}

I am running in 16bpp, 1280x1024, in VMware. Any idea why I can’t get a
video mode?–

Hmmm… I don’t have any of those components except SDL 1.0.1, so I
can’t do a whole lot of debugging on it now.

I can’t think of anything offhand that would cause these errors.
Do you get any messages from your cerr output?

Have to check later.

Is there anywhere I can download a (preferably simple) Windows
executable SDL-1.0.1 program? If it runs in VMware, at least that’s an
existence proof. If it doesn’t run, I’ll know that perhaps it’s not just
my app.–

Hi,

Are You sure that this is not W2000 RC2 bug? Have you tried to compile

and run this program under Win9x or NT?

If you want you can download simple SDL 1.0 application at

http://159.148.172.198/engine/Engine%20Docs/TEST1.RAR
It has worked under Win98 and WinNT 4.0 SP5

I got some friends to try it. It didn’t work on Win2000RC2 not in
VMware, or in WinNT4 not in VMware.

I get this error:

Couldn’t set 640x480x8 video mode: DirectDraw2::CreateSurface(PRIMARY):
No DirectDraw hardware

Once again, I am running 1280x1024x16, in Win2000RC2, in VMware-1.1.2,
on Debian GNU/Linux 2.1 (slink).–

I get an application error, which is dereferencing a null pointer.

I’ll try it on non-VMware Windows variants when I get a chance.–

Does VMWare even support Direct X?On Tue, 4 Jan 2000, Marc Lepage wrote:

I don’t believe so. Is there a way (command line option?) to force SDL
to not use DirectX?–

Ahhh. You can set the environment variables:

set SDL_VIDEODRIVER=windib
set SDL_AUDIODRIVER=waveout

If I get a chance, I’ll see if I can get the detection code to try to
create a DirectDraw surface to detect this condition.

My app (and Wurm) still yield this error:

Couldn’t set 640x480x16 video mode: DirectDraw2::CreateSurface(PRIMARY):

Is it possible the environment variables are not working for me? They
appear to be set. Perhaps I am still messing something up?–
