Problem with <modified> GZDoom

[bed.intruder]

Hi. I compiled GZDoom without any errors, but i have some problems.
(Version is 1.5.6 (r1124M))
What I did:
-renamed base pack (gzdoom.pk3) in version.h to base.pk3, and in game dir too;
-made "IWAD" pk3 (gamedata.pk3) from doom2.wad;
-added empty lump "GAMEFILE" into "IWAD";
-modified iwadinfo.txt in base.pk3:

Code: Select all

IWad
{
	Name = "My Game"
	Autoname = "MyGame"
	Game = "Doom"
	Config = "Doom"
	Mapinfo = "mapinfo/doom2.txt"
	Compatibility = "Shorttex"
	MustContain = "GAMEFILE"
	BannerColors = "a8 00 00", "a8 a8 a8"
}

-modified D_main.cpp:

Code: Select all

//function D_Main()
...
//FString iwad = CheckGameInfo(pwads);
FString iwad = "gamedata.pk3";

-modified D_iwad.cpp:

Code: Select all

//function IdentifyVersion()
...
if (iwadparm)
	{
		custwad = iwadparm;
		FixPathSeperator (custwad);
		if (CheckIWAD (custwad, &wads[0]))
		{ // -iwad parameter was a directory
			iwadparm = NULL;
		}
		else
		{
			DefaultExtension (custwad, ".pk3");
			iwadparm = custwad;
			mIWadNames[0] = custwad;
			CheckIWAD ("", &wads[0]);
		}

Today I launched compiled GZDoom, and I had exception:
Access violation reading location 0x00000000
at this line:

Code: Select all

mIWadNames[0] = custwad;

Can you help me? Thanks in advance

IWADINFO still needs the Names block. Without that the system does not work. The way you hacked in your custom IWAD is cannot work. You have to set the name in the IWADINFO lump.

You should not modify the source code here.

Anyway, good luck with that. Your mod will be eternally locked to your custom EXE if you make such changes. I strongly recommend to forget this. Eventually ZDoom will be able to install user-made IWADs but if you do what you plan to do here your WAD would not be among them.

Thanks. But do I need to return DefaultExtension parameter to ".wad", or not?

I'd say yes because most IWADS are wad files (I'm not sure a pk3 or pk7 IWAD exsists)

Do you never pay attention to the last post date? This has been sitting without response for more than a year. (Also I doubt your input is going to do the OP any good, seeing as they haven't even been here in about as long.)

Wait, we're already in December 2011?

Are you sure?

[edit]Hah, Gez beats me

[NeuralStunner]

I actually have no idea why I said it that way.

... It's been since last year, anyway.
