For me none of above worked for Tesseract v 4.0. So I took an unorthodox 
approach as follows:

- Got a MAC Virtual machine up and running
- Install Homebrew
- Install Tesseract using Homebrew (4.0)
- Copied the whole Cellar folder (as it contains all dependencies for 
tesseract)

Then comes the fun part.

- All libs in the various folders refer to each other via a path convention 
as "/usr/loca/Cellar/leptonica/lib/lebt5.dylib"
- The output libtesseract.4.dylib refers to leptonica and leptonica refers 
to jpg, tiff etc libs
- So we have to update all libs so that the paths being referred from 
"usr/local/Cellar/leptonica..." should change to "../../../leptonica" for 
all libs
- We can use otool -L  to get that (otoll is part of XCode 
command line tools)
- Then we can use install_name_tool -change to change references to dylibs
- It was a hard process but I did that one by one and here are the command 
(provided you are in the pwd of CopyOfCellar/tesseract/bin )

install_name_tool -change /usr/local/opt/leptonica/lib/liblept.5.dylib 
../../../leptonica/1.78.0/lib/liblept.5.dylib  tesseract 

install_name_tool -change /usr/local/opt/leptonica/lib/liblept.5.dylib 
../../../leptonica/1.78.0/lib/liblept.5.dylib  
/LocalPathofCopyOfCellar/tesseract/4.0.0_1/lib/libtesseract.4.dylib

install_name_tool -change /usr/local/opt/libpng/lib/libpng16.16.dylib 
../../../libpng/1.6.36/lib/libpng16.16.dylib 
/LocalPathofCopyOfCellar/leptonica/1.78.0/lib/liblept.5.dylib

install_name_tool -change /usr/local/opt/jpeg/lib/libjpeg.9.dylib 
../../../jpeg/9c/lib/libjpeg.9.dylib 
/LocalPathofCopyOfCellar/leptonica/1.78.0/lib/liblept.5.dylib

install_name_tool -change /usr/local/opt/giflib/lib/libgif.7.dylib 
../../../giflib/5.1.4_1/lib/libgif.7.dylib 
/LocalPathofCopyOfCellar/leptonica/1.78.0/lib/liblept.5.dylib

install_name_tool -change /usr/local/opt/libtiff/lib/libtiff.5.dylib 
../../../libtiff/4.0.10_1/lib/libtiff.5.dylib 
/LocalPathofCopyOfCellar/leptonica/1.78.0/lib/liblept.5.dylib

install_name_tool -change /usr/local/opt/webp/lib/libwebp.7.dylib 
../../../webp/1.0.2/lib/libwebp.7.dylib 
/LocalPathofCopyOfCellar/leptonica/1.78.0/lib/liblept.5.dylib

install_name_tool -change /usr/local/opt/openjpeg/lib/libopenjp2.7.dylib 
../../../openjpeg/2.3.0/lib/libopenjp2.2.3.0.dylib 
/LocalPathofCopyOfCellar/leptonica/1.78.0/lib/liblept.5.dylib

install_name_tool -change /usr/local/opt/jpeg/lib/libjpeg.9.dylib 
../../../jpeg/9c/lib/libjpeg.9.dylib 
/LocalPathofCopyOfCellar/libtiff/4.0.10_1/lib/libtiff.5.dylib

Once all above is done the tesseract becomes standalone provide you keep 
all the libs and includes in the folder structure as in original Cellar.

export TESSDATA_PREFIX=../share/tessdata

Now if some body can make all that into a bash script that will be great.

Stefan,
Please make the mac binaries available for both 3.05 and 4.00 similar to
windows.
I noticed that you have posted the test version for standalone Tess.
Thanks!

PS: Are the Travis created binaries available for download by users?

Building Tesseract with HomeBrew or MacPorts is much easier than with your 
script, and it simply works. End users who want to run Tesseract don't need 
HomeBrew or MacPorts. They only need some libraries which can be copied and 
distributed with the tesseract executable.

Re: [tesseract-ocr] Re: Standalone Self-contained Tesseract-OCR for Mac

2017-05-01 Thread 'Stefan Weil' via tesseract-ocr 


I had a look on that shell script. The published version does not work 
because it tries to build Tesseract without building the dependencies 
(libjpeg, zlib, libpng, leptonica) first. This can be easily fixed in the 
first lines of the script. Now it builds those dependencies. It also starts 
building Tesseract 3.05, but fails when linking the tesseract executable 
because of a missing symbol _fmemopen in liblept.


This problem is caused by an unusual build of Leptonica: instead of the 
normal configure / make, the script calls ./make-for-local which uses a 
hand-built makefile (maybe made for Linux). I'm also surprised that TIFF 
support is disabled for the Leptonica build and doubt that this will work 
with Tesseract.

Hi Shree

Sorry for the delay in replying but I'm struggling to get a successful 
build now.  I'm attaching my shell script for you to look at but the 
failure seems to be related to aclocal being called inside autogen.sh.

To be honest I'm not confident that things are building OK elsewhere as I 
see a variety of error and warning messages appear even though the relevant 
script finishes with "success"! I'm not a C/C+ etc coder, I do all my 
programming using LiveCode.  I'm just trying to get a reliable build of a 
portable version of Tesseract that I can drive through a command-line 
interface.  The OCR capability I'm trying to provide using Tesseract is 
just a part of a much larger app.  LiveCode allows me to build an app on my 
Mac to be deployed on Mac, Windows & Linux.  In each case the only code I 
need for each target deployment is a command line or two that runs 
Tesseract with a given set of source files that my app has 
extracted/created elsewhere. In order to make installation easy I include a 
portable version of Tesseract amongst the resources for my app.

As I'm not a C etc. coder (I last wrote serious C several decades ago!) I'm 
not able to judge which error/warning messages are significant or figure 
out how to fix them.  I was hoping to follow a recipe that would reliably 
build a portable Tesseract for the Mac and Windows.  I'm just trying 
different combinations of sub-builds until I find one that works, which is 
why I ended up with a combination of older versions of the dependencies. So 
I'm not a good person to ask to build this and report errors etc!

Best regards

Peter

Re: [tesseract-ocr] Re: Standalone Self-contained Tesseract-OCR for Mac

2017-04-20 Thread Peter Reid 
Hi ShreeDevi

Thanks for your advice anyway, it got me thinking about the problem in 
other ways. I'm pleased to say that I managed to get a build script that 
works using the following versions of the libs:

LIBJPEG_VERSION=9b
ZLIB_VERSION=1.2.11
LIBPNG_VERSION=1.6.29
LEPTONICA_VERSION=1.71
TESSERACT_VERSION=3.04.01

I couldn't get it to work with any later versions of Leptonica (1.74.1 is 
the latest) or Tesseract (3.05.00 is the latest v3).  Despite this, I now 
have a working standalone Mac version of Tesseract that I can drive from my 
own code!

Apart from the actual files themselves, it's necessary to set 2 environment 
variables:

TESSDATA_PREFIX - set to the parent folder for the tessdata folder
DYLD_LIBRARY_PATH - set to the path up to and including the lib folder

I've included my version of the build script in case anyone else needs to 
do something similar.

Thanks again

Peter

but had several failures, so I've backtracked to earlier versions in order 
to get successful builds.  The latest release versions are the following I 
think:

ZLIB_VERSION=1.2.11
LIBJPEG_VERSION=9b
LIBPNG_VERSION=1.6.29
LEPTONICA_VERSION=1.74.01
TESSERACT_VERSION=3.05.00

My latest attempt succeeded to build zlib and libjpeg but failed with 
libpng:

Undefined symbols for architecture x86_64:
  "_inflateValidate", referenced from:
  _png_inflate_claim in pngrutil.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see 
invocation)
make[1]: *** [libpng16.la] Error 1
make: *** [check] Error 2

I've looked at the link about compiling Tesseract but it describes MacPort 
and HomeBrew only for Mac deployment, which do not generate standalone 
tesseract binaries.  My apps need to include a runnable version of 
tesseract that doesn't require any installation.  I can do this for Windows 
as the compiling web page gives the details, but I'm having to try to build 
the standalone version for the Mac myself.  This is why I'm going through 
this process!

Thanks again

Peter

If you are building tesseract 4.0, you need Lept 1.74

[tesseract-ocr] Re: Standalone Self-contained Tesseract-OCR for Mac

2017-04-18 Thread Peter Reid 
Hi ShreeDevi

I have tried the latest version of Leptonica but I get numerous warnings 
(38 of them, mainly about implicit function definitions) and a fatal error 
'endian.h' not found.  The build finishes saying that Leptonica has been 
built OK and its library appears in the lib folder.  However, when I try to 
build Tesseract, I get the following error:

checking for leptonica... yes
checking for pixCreate in -llept... no
configure: error: leptonica library missing
Configuration done, now Building
make: Nothing to be done for `install'.
Tesseract build failed. Exiting.

So I'm not better off with the latest version.  At least with version 1.73 
I don't get the warnings and error messages when building Leptonica even 
though the Tesseract build fails.

Thanks

Peter
