Error C2440

[exidis]

Alright so I'm getting these errors upon compiling... any solution?


c:\documents and settings\cory\my documents\visual studio 2008\projects\test v1\test v1\testv1.cpp(19) : error C2440: 'initializing' : cannot convert from 'int' to 'const DamagePacketFp'

Help anyone?

const DamagePacketFp meleeDamage = DMG_PACKET_PROC;
const DWORD* monsterList1 = MONSTER_LIST1;
const BYTE** monsterList2 = MONSTER_LIST2;

You can't do this. DMG_PACKET_PROC, MONSTER_LIST1, and MONSTER_LIST2 are all defined as integers. You cannot cast them to various types of pointers like this.

I don't know what you're trying to do, but whatever it is you're going about it the wrong way.

[exidis]

So you don't have any helping words on this?

I tried used reinterpret_cast and static_cast, both turned up no positive results.

Using c style casts:

typedef int (__cdecl * DamagePacketFp)(int, int, int, int, int, int, int);
const DamagePacketFp meleeDamage = (DamagePacketFp)DMG_PACKET_PROC;
const DWORD* monsterList1 = (DWORD*)MONSTER_LIST1;
const BYTE** monsterList2 =(const BYTE**) MONSTER_LIST2;

Okay that fixed my problem with those 3 lines, however I'm getting a LINK error now:

1>LINK : fatal error LNK1561: entry point must be defined

No. No No. No no no no no.

C style casts do not solve the problem, they simply stop the compiler from reporting it. Even if you get this to compile, it will explode when you try to run it.

The problem is what you are trying to do is fundamentally flawed. It's not something you're allowed / supposed to do. You shouldn't be doing it at all.

Whatever you're trying to do, you're going about it in completely the wrong way. I can't give you any more info on how to fix it because I don't know what you're trying to do -- perhaps you could say what it is you're trying to accomplish so that I could show you how to do it.

I wasn't saying that casting would solve the "problem "- and to be honest I don't really know
what is the OP is really trying to achieve - only he knows that (maybe he's trying to crack some game or the other).
