Arghh.. getting errors in the jpeg.library includes with VBCC

[Jose]

Ok, I had the ma program thing ready to compile for the >2.0 version but I'm getting errors with the jpeg.library includes! Has anyone managed to get this working with VBCC?

Here's my output:

Mmmh, I think your jpeg includes are not compatible with VBCC. They seem to be for SAS/C only.

>typedef __asm ULONG

Adding #define __asm in the begining of the file could help here...

>typedef __asm ULONG (*JPGD_HOOK_PROTO)( register __a0 void

Change "register __a0" to "__reg(a0)". Same for other similar instances...

[Jose]

@itix

Thx. I'll try that...

[Jose]

Ok, it helped, but know I'm geting this one:

>#define __asm
error 272 in line 4 of "additionalincludes/jpeglibrary/jpeg.h": macro '__asm' redefined unidentically
1 error found!
....

If I take off "define__asm" at the beggining  I get :

The normal includes don't get errors if I take off the jpeg.library ones...

[Thomas]

The jpeg include files really look weired. I know I got it running with VBCC, but I don't remember how. You should try to remove all occurences of __asm, __saveds, __stdargs, register and __a0, __a1, etc.

Bye,
Thomas

[itix]

Remove every __asm from jpeg includes then... then it should work.

[Jose]

Tryed your suggestions but still didn't work...
Can anyone that managed to get this working send me his working jpeg.library includes? I still haven't managed to get it working.. :oops:

@Jose

If decoding jpegs is sufficient for your needs, why not try using datatypes (this assumes, of course, OS3.x minimum) ?

[Jose]

@Karlos

Never used them. Also heard they're slower. But I wanted to learn how to use them for a long time so maybe now it's time...I'll check out ma DevCD tonight...

[Jose]

Just checked some Datatypes stuff and dammit I still haven't read some Intuition parts of the RKM Libs let alone the Boopsi stuff that I would need to know to just start learning Datatypes now... Later on it will happend though 8-)

@Jose

It doesnt have to be that hard.

Here is some code that forms the ImageLoader class for the AmigaOS implementation of my OOP framework. Sorry it's C++, but at the same time you will see the OS functions you need. They are

NewDTObject( ) - creates a new (datatype) object (specified as a filename which is really handy!)

GetDTAttrs( ) - gets attributes of the object, in this case writing the bitmap data into a struct BitMapHeader and so on.

DoMethod( ) - invokes a method of the object - in this case PDTM_READPIXELARRAY which I use to get the raw RGB data out of my datatype, storing it in my own ImageBuffer object (which is a simply chunky pixel raster type thing).

DisposeDTObject( ) - destroys the datatype object once your'e done with it.

It's not as hard as it looks - I myself had to ask here originally for an example also (can't find the thread, but it must be here some place).

As for speed, it is highly subjective. 680x0 apps on my system can load jpegs in a flash since the decoding is using PPC ;-)

[Jose]

@Karlos

Ok, I'll take a look at that...
Meanwhile, if I find a very cheap SAS package I'll probably give it a try.

[Karlos]

@Jose

Well, that example source is a small component of a much larger system so you won't be able to compile it. I just had it handy as a way of showing a quick way to load image data using datatypes. The same overall method is equally applicable to C code, so you should be able to do it in VBCC.

Using datatypes also, of course, allows you to keep your image as a struct BitMap if that is what you want. My needs were different (I just wanted the RGB data), since I had my own ImageBuffer class.
