Title: Sint64
Post by: Peter on January 23, 2016, 11:53:59 AM

Hi Charles,

I use for a  Sint64 type a QUAD type,  is this alright?

Hi Peter,

Sure. (the o2 quad type is a 64bit signed integer)

Thanks Charles,

I'm writing just a SDL2 library for OxygenBasic.
But I can the sdl_header not directly use, especially the keys definition from sdl.h.
Therefore I do everything by hand.

At the moment, I have trouble with SDL_Rect, somehow it does not work.  ???
I can not imagine that this definition is wrong:

typedef struct SDL_Rect
{
Uint16 x
Uint16 y
Uint16 w
Uint16 h
} SDL_Rect

Peter, a C int is likely to be 32-bit and you are using 16-bit integers.

Hi Jack,

 :)

typedef struct SDL_Rect
{
  int x, y
  int w, h
} SDL_Rect

But still no success.

hi Peter look into link:

https://wiki.libsdl.org/SDL_Rect

so if i understand this thing this must be type not typedef

something like we use in windows
TYPE Rect .rc

no, I need no help, I only was saying that I have trouble  with SDL_Rect.
nonetheless,  thanks for your help.

that poblem is somewhere else and I will find it.

Aurel you need  a warm oven to warm up your brain cells.   ;D

Hi Peter,

We don't have a core definition for uint16, but you can use word to define it before the C SDL headers

typedef word uint16

Title: Re: Sint64

Thanks Charles,

I already did it.

Code: [Select]

TypeDef byte  uint8
TypeDef word  uint16
TypeDef dword uint32
TypeDef short Sint16
TypeDef int   Sint32
TypeDef quad  Sint64[/code]

Good point Peter. I didn't consider the weather being a factor.  ;D

I would wish you well but I would be lying. Sorry life didn't work out for you.

Hi Peter,

I looked at the definition in SDL_stdinc.h

Code: [Select]

typedef int16_t Sint16;
/**
 * \brief An unsigned 16-bit integer type.
 */
typedef uint16_t Uint16;
/**

so the solution might be to define before the SDL headers:

typedef word uint16_t
typedef short int16_t

Hi Charles,

the type-definition what I have is okay!

another thing here is an error  message in this typedef  struct.

 

Code: [Select]

typededef struct SDL_Surface
{
  Uint32 flags               
  SDL_PixelFormat *format   
  int w, h                   
  int pitch                 
  void *pixels             
  void *userdata           
  int locked                 
  void *lock_data           
  SDL_Rect clip_rect         
  struct SDL_BlitMap *map  '< here
  int refcount               
} SDL_Surface
I  got a solution, but whether this is a proper solution I have to test out.

The problem is that SDL_BlitMap is an undefined private structure.

The solution is to define it before including the SDL headers

typedef struct SDL_BlitMap {}

or hack:

typedef sys SDL_BlitMap

Post by: Peter on January 28, 2016, 07:48:13 AM

Thanks Charles,

that was my solution!

Code: [Select]

typedef struct SDL_BlitMap SDL_BlitMap

Hi Charles,

solved!
Sdl2 works now

Very good!

I will need to adjust o2 struct semantics in a future release, to comply with C.
