weird includes // glGenTextures

[Michael Sgier]

Hello
in en.h i've:
#include "player.h"

if i do now include in player.h another header file:
#include "sod.h"

i get errors in en.h:
en.h:54: error: syntax error before `*' token
that's at this line:
public:
CPlayer *player; //here now the above error

if i do it like that in player.h:
//#include "sod.h"

there's no error. WHY? This looks weird to me.
All header files begin like this:
#ifndef __PLAYER_H
#define __PLAYER_H
same for all header. So ifndef __EN_H etc.

secondly, I'll post this also in a OpenGL newsgroup:
This, under Windows generates a new texID each time
it gets called but not under Linux. WHY? My model doesn't
get drawed and i guess because of that.

glGenTextures(1, &this->texID);

THANKS and regards
Michael

This is a bit too short to give you an appropriate answer. Maybe, something
in your header is wrong, like a missing semicolon or something, and that
produces an error later in the other file.
All header files begin like this:
#ifndef __PLAYER_H
#define __PLAYER_H
same for all header. So ifndef __EN_H etc.
Those identifiers are reserved, like all that contain two consecutive
underscores.

If your model isn't drawn, it probably doesn't have to do with the texure.
What makes you think so?
glGenTextures(1, &this->texID);

Did you check for errors after that call?

Suspect (1) missing semicolon right before the public; or
(b) you're compiling as C instead of C++. If neither is so,
try to get the code into the smallest sample possible to
post here and hopefully in the process you'll detect
the problem yourself, if not, we'll have a look.

Hello again
so here's more code.
THANKS
Michael

player.h:

#ifndef __PLAYER_H
#define __PLAYER_H
//#include "ogro.h" // IF I INCLUDE ogro.h the error gets fired
#include "camera.h"
#include "object.h"
#include "terrain.h"
#include <typeinfo>
class CPlayer : public CObject

{
....
};

#endif


then the enemy.h:

#ifndef __ENEMY_H
#define __ENEMY_H
#include "entity.h"
#include "vector.h"
#include "player.h"
#include <typeinfo>

class CTerrain;

enum AIState_t
{
AI_UNCARING, // enemy is not scared and does not care
AI_SCARED, // enemy is scared and running away
AI_DEAD
};

class CEnemy : public CEntity
{
private:

protected:
int hitPoints; // hit points the enemy has left
float distFromPlayer; // distance this enemy is from player
float runSpeed; // speed of enemy when running
AIState_t aiState; // state of enemy thought

virtual void OnProcessAI() {}

void OnCollision(CObject *collisionObject)
{
// if this enemy collides with another enemy
if (typeid(*collisionObject) == typeid(CEnemy))
{
modelState = MODEL_IDLE;
velocity = CVector(0.0, 0.0, 0.0);
}
// if this enemy collides with the terrain (always)
else if (typeid(*collisionObject) == typeid(CTerrain))
{
position.y =
((CTerrain*)collisionObject)->GetHeight(position.x, position.z) + size;
}
else
{
}
}

public:
CPlayer *player; // HERE I GET THE ERROR IF I INCLUDE ogro.h in
player.h
....
};

#endif

and the ogro.h:

#ifndef __OGRO_H
#define __OGRO_H
#include "enemy.h"

class COgroEnemy : public CEnemy
{
....
};
#endif

Simple. egro.h uses the CPlayer class, which isn't defined til AFTER ergo.h
is included.

At the top of ergo.h include the line:
class CPlayer;

and your problem should go away.
