New_Irr example...compile errors

[MikeR]

Error Message:

C:\Irrlicht_examples\new_irr\new_irr\NewtonGame.h(3 : warning C4183: 'MainLoop': missing return type; assumed to be a member function returning 'int'
C:\Irrlicht_examples\new_irr\new_irr\NewtonGame.h(6 5) : error C2143: syntax error : missing ',' before '*'
Process terminated with status 1 (0 minutes, 3 seconds)
13 errors, 12 warnings

Here's the line it calls out:

Code: Select all

static dFloat  OnJumpRayCastPlacement (const NewtonBody* body, const dFloat* normal, int collisionID, void* userData, dFloat intersetParam);

I don't see where anything is missing.

I have tried adding a comma after static dFloat but it had no effect.

[dhenton9000]

which program is this, and where did you get it?

If its the one from me, dhenton9000, then I'm probably the only one who'll know what you are referring to?


I've only gotten this to compile under VC++ 6. Maybe you've got some kind or reserved word that VC doesn't have (normal????)

[MikeR]

This is the one you did.
I'm using vc toolkit 2003 with codeblocks as the ide. I got merciors tut to compile with only 1 warning.
I'm doing a test compile to get my compiler setup correctly for this example. I haven't changed any of your code.

Here is the whole code block...

NewtonPlayerController.h

Code: Select all

static dFloat  OnJumpRayCastPlacement (const NewtonBody* body, const dFloat* normal, int collisionID, void* userData, dFloat intersetParam);

[dhenton9000]

I wonder if the compiler somehow handles static keyword differently.

[MikeR]

I don't know. It should work the same.
Which lib file did you link to?

[FlyHigh]

The error means it probably didn't have a declaration for dFloat. You tried forward declareing it and including all nessecary files?

[MikeR]

That part is in the beginning of the protected part of the class:

Code: Select all

class CNewtonPlayerController  :public CNewtonBase
{
public:
	void changeCamera(IGUIStaticText* statusText);

CNewtonPlayerController();
virtual ~CNewtonPlayerController();

static int  _cdecl BeginContact (const NewtonMaterial* material, const NewtonBody* body0, const NewtonBody* body1);
static void _cdecl FinishContact (const NewtonMaterial* material);
static int  _cdecl ProcessContact (const NewtonMaterial* material, const NewtonContact* contact);
static void _cdecl SetPlayerMeshTransformEvent(const NewtonBody* body, const float* matrix);
static void _cdecl ApplyPlayerForceEvent (const NewtonBody* body);
void Init(ISceneManager *mgr,NewtonWorld* world,KeyItem* keys);
void createPositionText(gui::IGUIStaticText* posText);

dHenton said that it compiled fine for him with vc6. That's why I wonder which dll he linked to.

[dhenton9000]

I dont know, I think that dFloat thing might be something. I usually get this kind of error when theres a missing declaration, I think dFloat is defined for Newton, anyway, replace it with its real meaning (float I think) and see what happens.

[Acki]

I'm using Newton, too, and had no problems with it !!!

Did you include "stdlib.h" !?!?!
(Ans using namespace std)

dFloat is declared like this:

Code: Select all

//#define _NEWTON_DOUBLE_PRECISION__
#ifdef _NEWTON_DOUBLE_PRECISION__
	typedef double dFloat;
#else
	typedef float dFloat;
#endif

So you can use double or float instead....

[MikeR]

I don't find that lib anywhere. Where did you find it?

[MikeR]

I took your code above and made a header. Added it to the project and added "using namespace std;

I'm beginning to not like newton and raknet. Too many compiler errors when there really should be none becouse these are precompiled examples.

[Acki]

@MikeR: wich lib? stdlib.h is the standard includes from Dev...

As I told you, I'm using Newton and have no probs !!!
I did everything as it's explained in the tutorials, nothing more...

[MikeR]

From dev-dpp?? I'm using vc2003 toolkit with code::blocks.
Ill add that included header and see if that helps.

[Acki]

Oh, I thought you're using Dev, because of the link in your signature...
Well, there must be a similar header file for your environtment...

[latentdisposition]

I got it to compile in Code::Blocks with the toolkit by changing all of the dFloats to regular floats. It still had several warnings but it did compile and run perfectly.
