Unfortunately, I only had enough time to add TIFF support for Win64 and Linux for Imaging version for Deskew.
OSX support was nearly finished but I have no idea when I will be able to finish it.

Hi,

I just downloaded the latest Vampyre library but see that the support for TIFF under Lazarus was not added. Any idea when this will be added to this great library ?

Thanks,

regards
CorBee

I've been working on TIFF loader/saver for Imaging that won't need LibTiff as compiled objects
so in few weeks there will be TIFF support on more platforms (and LibTiff only as an option).

I dont have any time to explore compiler flags, now.
I just copy here my compiled old version (3.9.1, but adaptated for 3.9.4 pas unit)

I hope that soon will deal with this.

PS: Some explanations for this version.
This code work as Windows as MacOsX.
There is two libtiff.a in pack.
libtiff.a - for mac os
libtiff-win.a - for windows (for compile - rename it to libtiff.a)

PPS: For compiling I use this link :
  http://www.kyngchaos.com/macosx/build/libtiff
  (some compiler flags are here)

jsj,
seems like the problem is not in GCC, or at least not in CPU architecture.

I did some experiments and the static lib (libtiff.a) produced by GCC is different
when you use "-arch i386" than with no flags. 64bit one is roughly 2x bigger in size
than 32bit one.

Also FPC gives this message:
ld: warning: ignoring file ./libtiff64.a, file was built for archive which is not the architecture being linked (i386)
when trying to link to x86_64 library.
This message is not displayed when linking library generated with "-arch i386".

Anyway, for both libraries linking always ends with:
Undefined symbols for architecture i386:
  "_TiffGetVersion", referenced from:
Maybe symbols are not properly exported or something :(

Galfar, registration was successful =)

About tifflib under Mac - I forget compilation keys, but I have already compiled tifflib 3.9.1 under mac.
I will upload it... soon...

But with tifflib 3.9.4 under macos I have a problem..
I was build obj files for i386 architechture, but for success compilation need
Code Select
{$Linklib libtiff} and libtiff.a - x86-64 architechture somehow (i view it by otool)

Therefore I need correct compilation keys.
Now I compile tifflib as:

./configure CFLAGS="-arch i386"
make

But it not enough...

PS: sorry my english, but i think you understand me))

Galfar,
Tiff with jpeg codec dont supported by default (even under win32 lazarus, i cant tested it under delphi).
As I understand - tifflib must be compeled with -jpeglib parameters...

Jus, I recompiled the new imaginglib with tifflib 3.9.4
Under win32 - everything works, but under the macos - the same error again...
(ld: symbol(s) not found for architecture i386)
Maybe somebody know how to get more info from linker?
The worst thing - I seem to have forgotten the keys that I have compiled tifflib 3.9.1 (
And now again I try to resolve this problem...

Just use "-arch i386" parameter to compile tifflib object files


Hi jsj,

  I'm very insterested in using Tifflib. The problem is that I'm not very familiar with compiling c++ files. Could you please provide some more detailed information how to build such a tifflib to use it in vampyre lib? And where/which version did you use to compile? I have tried to load the libtiff source code (http://www.libtiff.org) into xcode, but it didn't worked.  :(

Could you please check if TIFFs with JPEG compression are working with TiffLib compiled for MacOS?

I was made gcc compiling libtiff under win gcc (mingw32).
Tiff's are loaded.

But under Mac OS don't work.
"Linking error
Id: symbol(s) not found for architecture i386"

I try to use as mingw32 obj's as mac gcc obj's.
Don't work ;(

Any ideas?
