Hello everyone, i am trying to learn C++ game development with this
When i opened the template a few days ago, it worked fine. Now i open
the (freshly downloaded or the one from a few days ago) template and i
get an error:
Being new to visual studio, and being an amateur C++’er I don’t know
what caused this. Can somebody clarify this?
Windows 7 64 bit / Visual Studio 2008

I am struggling with the same problem as well.
It doesn’t work on W7 / VC++ 2008 / Release Win32 and on W7 / VC++ 2010
/ Release Win32.
DirectX SDK June installed succesfully.
The problem seems to be a null pointer access, likely due to
SDL_GetVideoSurface returning NULL. (You should be able to verify that
in the debugger, if you find the Locals pane and look at the value of
‘s’.) It sounds like SDL initialization is failing somewhere. One thing
to try: make sure your video card drivers are up to date. Other than
that I’m not sure what could be the cause.
You might try adding a line of code like:
printf("SDL error: %s\n", SDL_GetError());
Try copying that in after each SDL call (SDL_Init, SDL_SetVideoMode,
etc.) in that section of code. That should hopefully display a more
informative error message in the console.
it crashes before i get to see a variable named ‘s’. crashed at
If I put in the prints, it puts out “Current mouse doesn’t have cursor
support” and “SetProp() failed:invalid window handle”
this is the line (in the !init() loop in template.cpp) after which no
output is given anymore;
surface = new Surface( SCRWIDTH, SCRHEIGHT, (Pixel*)s->pixels, s->pitch );
any further suggestions?
I googled that SetProp error message and found this SDL forum thread:
Unfortunately, they don’t seem to have come up with a solution. (I also
found another thread here on DevMaster about it:
So it seems you guys are not the only ones having this issue with these
Unfortunately I don’t have any more suggestions. I don’t use SDL myself,
so this goes beyond what I can guess at.
I got it to work, the problem was my GPU driver, i have a ATI HD4890 and
the 4000 series is only supported up to version 12.6 of Catalyst control
center and i had 12.10 running, so i installed an the older version
(12.6) which is compatible with my card and it ran just fine.
