Wrong JPEG library version #34

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. compile leptonlib-1.65 according README.html
2. compile prog
3. run ./threshnorm_reg: 
Wrong JPEG library version: library is 80, caller expects 62
Error in pixReadStreamJpeg: internal jpeg error
Error in pixReadStream: jpeg: no pix returned
Error in pixGetInputFormat: pix not defined
Error in pixRead: image not returned
Error in ./threshnorm_reg: pixs not made

What version of the product are you using? On what operating system?
Mandrivalinux 2010, libjpeg8 (most of the sw is build against libjpeg8 or
libjpeg7 so I can not downgrade to libjpeg6)

In meantime I found solution ;-):
I replace jpeglib.h from leptonlib source with link to system jpeglib.h
(/usr/include/jpeglib.h), recompiled leptonlib and than it works.

The jpeg library has been stable at 62 for years.
I knew that 7 was out (as an interim version), but
didn't realize that 8 is now available.

The best solution for leptonica is to remove the special
version of jpeglib.h 62 from the distribution.

Thanks for pointing out the problem.

Hi all leptonica lovers and coders,

Thanks for this nice library for computer visioners. I've completely compiled
Leptonica-1.65 including libgif, libtiff, libjpeg, zlib and libpng libraries. In
addition, i aimed to convert headers to use in Delphi ( pascal ). in my 
experiments,
my first triyings are successfull to read images from disk/ and some simple
operations to use pix format.
Thanks for all.

1.66 is released.

all jpeg header files have been removed from src
(one of them is "*.hide", which is effectively removed).

Nice to have this old cruft out of there.
