In my experience, Import/EndImport does work with Tailbite (I use it in PureZIP to import the ZLIB functions).

At me here this code gives out a mistake:

Import "zlib.lib"
  crc32()
  inflateReset()
  inflateInit_()
  inflate()
  inflateEnd()
EndImport

ImportC "libPNG.lib"

	png_read_png(a,b,c,d)
	png_get_IHDR(a,b,c,d,e,f,g,h,i)

I am not sure the problem is related to Tailbite.
There are some problems using ZLIB and a PNG decoder, as both use ZLIB functions : for example, PureZIP compiles Ok, but if you use it with the purebasic PNG decoder you get a linker error.
Did you try to use the 'As' keyword ? Maybe it helps ?

Code: Select all

Import "PureZIP_O.lib"
  ZLIBCompress(*DestBuffer, *DestBufferLen, *SourceBuffer, SourceBufferLen.l) As "_compress@16"
  ZLIBUnCompress(*DestBuffer, *DestBufferLen, *SourceBuffer, SourceBufferLen.l) As "_uncompress@16"
...
EndImport

Programm not correct work in ProcedureC command.

Well all like has turned out to realize all.
Now I have learned PureBasic to keep PNG files with Alpha the channel.

Thanks ALL.

Whoever's working on this, thanks for your time and effort. There is a small bug with calling procedures. It seems if you call a procedure by pointer once you can't call it by name after that. This is good PB code but Tailbite chokes on it:

Code: Select all

Procedure test()
  ProcedureReturn 1
EndProcedure

ProcedureDLL doit()
  CallFunctionFast(@test())
  test()
EndProcedure

doit()

@netmaestro : could you test this Version http://www.purebasicpower.de/downloads/ ... er1.83.exe

i tested it with your example and it worked.

Regards Klaus

Yes, it seems fixed. Thanks for the quick work!

With my snipped you can, but it won't be helpful

.

Well I will send you a PM with the files.

well, it is a bit delayed due to good weather

here is a new version to test : TailBite V1.84

Hi ABBKlaus,

Sorry if I am asking the obvious, but are you now the main maintainer of Tailbite?
And is there a page (link) where your latest release of tailbite can be downloaded at any time?

EDIT: Removed question on quirks. Found the help.

I did read through this thread but ended up a bit confused.

I get the impression that tailbite development has forked.
I am after the main branch or fork.

A huge thanks to everyone who has made an effort to get Tailbite back on the road!

Really appreciated!

PS:
The lib created is a real lib - (can be used standalone) or needs a dll?
Import seems to dislike it.

Thanks!

Now it works!!! Thanks

A minor bug: in the statusbar(Desc file for the PBLibMaker) things are going wrong.
