C Combatability

[Emil_halim]

Hi all ,

I have a Zlib.h header file , so the next line is not understood by OxyGen, any help?

Code: [Select]

typedef voidpf (*alloc_func) OF((voidpf opaque, uInt items, uInt size));

it gave this Error

ERROR:
unknown type
WORD:    voidpf

LINE:    77
FILE:    zlib.h

Edited:

 BTW i have the next code in a header file that included in zLib.h , but seems Oxygen did not see it.

Code: [Select]

#ifdef STDC
   typedef void const *voidpc;
   typedef void FAR   *voidpf;
   typedef void       *voidp;
#else
   typedef Byte const *voidpc;
   typedef Byte FAR   *voidpf;
   typedef Byte       *voidp;
#endif

Have an other Error

consider the following code in c language.

Code: [Select]

#ifndef FAR
#  define FAR
#endif

...
.....
...... and later

  typedef Byte       FAR      Bytef;
                     ^^^
                        |
                this is ok with c 
                but not with Oxygen

the FAR  term is nothing by deceleration  (#define FAR) , so when parse the last line (typedef Byte  FAR   Bytef) it must be like that (typedef Byte  Bytef)

Oxygen give this error

ERROR:
'FAR' is already defined
WORD:    Byte
LINE:    264
FILE:    zconf.h

Code: [Select]

typedef voidpf (*alloc_func) OF((voidpf opaque, uInt items, uInt size));

It gets thrown by the OF word
Is there a definition of OF?

Code: [Select]

#ifndef far
# define far
#endif

typedef byte far bytef
bytef b

print sizeof b

I have a fix for this situation.

Oxygen does not have a separate preprocessor layer like C. This has advantages, like the ability to  create scoped/localised macros, but gets us into trouble with C headers which plonk macros in strange places.

no the problem was something belong C directives i.e #case sensitive ........

I have a fix for this situation.

hope to see it

i have a simple idea , make a new directive for preprocessor stuff , so that it will be 100% compatible with
C , or it will be as it already is , what do you think ?

BTW the fast , easy and  short way for achieving certain things with Oxygen Basic is attractive me to this
great language.

Strange why others can't see the obvious that O2 is probably the most relevant version of Basic available. (followed by ScriptBasic of course ...  )

John,

I think Oxygen Basic needs a good help Files and variable difficult tutorials these will demonstrate the power
and advantage of Oxygen Basic.

I agree...currently is very confusing from people outside to figure what is what .

Yes, I seem to be heading in that direction. We could preprocess  all the #defines first, and it may not require a separate C switch. Oxygen has its own set of dynamic macro constructs as well.

With regard to tutorials, I hope these will emerge eventually from all the examples we have accumulated.

I think that will be the best solution here , No more Directives .......

[Charles Pegge]

Case sensitivity is a potential problem.

#case capital is useful for handling fully capitalised words, treating all others as case insensitive.

Hi,
A tutorial will be very welcome...

[Charles Pegge]

I would like to see something like a code database, with hypelinks giving easy access to all the examples.  All my man-hours at present are spent on development.

[Emil_halim]

Hi Charles ,

is there any progress here?

Emil.   

[Emil_halim]

Hay any body home?

[Charles Pegge]

This is an intricate operation. I need a lots of spare time to go through this.
