I guess that your version of tesseract is 3.01 not 3.02.

Try commenting lines 582-586 in baseapi_mini.h
//#if !defined(__windows__)
  /** Sets Wordrec::fill_lattice_ function to point to the given function. */
//  void SetFillLatticeFunc(FillLatticeFunc f);
//#endif

GoogleCodeExporter commented 9 years ago 
Yes, you are right; tesseract is version 3.01.

Commenting the lines does not help. I get the same output as before.

Anyway, thanks for your time! Much appreciated! :)

GoogleCodeExporter commented 9 years ago 
What is the error message? Is it still the same?

Original comment by FreeT...@gmail.com on 2 May 2012 at 7:08

GoogleCodeExporter commented 9 years ago 
Clean it first.

python setup.py clean

Yes, I did run a clean first, but apparently I didn't pay enough attention: the 
error is now a different 'undefined symbol':

You have three choices:
1. compiles the svn version of tesseract-ocr  
http://code.google.com/p/tesseract-ocr/wiki/TesseractSvnInstallation
2. Download the compiled version of python-tesseract
http://code.google.com/p/python-tesseract/downloads/list
3, comment out all the missing library in baseapi_mini.h
lines: 404-406
  //Boxa* GetComponentImages(PageIteratorLevel level,
  //                         bool text_only,
  //                         Pixa** pixa, int** blockids);

Thanks for your suggestions!

I tried #3, which didn't work. I still got the 'undefined symbol' error, 
although it was yet another different 'symbol' this time.

Suggestion #2 is not really a possibility, as Arch Linux doesn't use rpm or 
deb. There are tools to convert those package types, but I would rather avoid 
them.

I went for suggestion #1, building tesseract-ocr from SVN. It got build and 
installed without problems (I have tested it from the command line), but when I 
try to build python-tesseract I know get the following error. It is probably a 
missing dependency, but then I am not really sure what it should be. Any ideas?

Img.h should be in either
/usr/include/tesseract/img.h
or
/usr/local/include/tesseract/img.h

where is your tesseract svn indeed installed?

if the directory /usr/local/include/tesseract is not used, remove it.

GoogleCodeExporter commented 9 years ago 
also referring to 
http://code.google.com/p/python-tesseract/wiki/HowToCompilePythonTesseract
the steps should be

python config.py
python setup.py clean
python setup.py build
sudo python setup.py install

My tesseract SVN installation is just in a subdirectory of my home. I figured 
that 'sudo make install' would make tesseract-ocr copy the appropriate files to 
/usr/local/include, /usr/local/bin, etc., but apparently it is not the case. It 
_does_ copy a few files to /usr/local/include/tesseract, but not img.h.

Should I use a specific prefix for the make install process? I could of course 
just symlink the files, but I would rather avoid those kind of hacks if I can. 
:)

just copy img.h to /usr/local/include/tesseract then

Original comment by FreeT...@gmail.com on 3 May 2012 at 10:00

Okay, for reference I needed to copy tesseract-ocr/image/img.h, 
tesseract-ocr/ccutil/tprintf.h and tesseract-ocr/api/tesseractmain.h to 
/usr/local/include/tesseract. It is now possible to build and install 
python-tesseract, but I still get errors when trying to import tesseract:

The path to libtesseract.so.3 on my computer is 
/usr/local/lib/libtesseract.so.3. Where does python-tesseract expect 
libtesseract.so.3 to be placed?

Original comment by digitald...@gmail.com on 3 May 2012 at 1:40

GoogleCodeExporter commented 9 years ago 
Are u sure u have only one version of tesseract in your system?

if so, cp libtesseract.so.3 to /usr/lib  as well

Original comment by FreeT...@gmail.com on 3 May 2012 at 2:58

GoogleCodeExporter commented 9 years ago 
Yes, I uninstalled tesseract 3.01 before installing from SVN.

But copying libtesseract.so.3 to /usr/lib solved the problem---python-tesseract 
now works like a charm! Thank you very much for your help! :)

You need to be consistent with the use of Prefix
In your case, it should be
./configure --prefix=/usr

By the way, send me your compiled package to me after running the following 
command

python setup.py bdist --format=gztar

Many thanks

patch for python-tesseract svn version against tesseract-ocr 3.01

Submitted By Ionut Biru

P.S. if u are using svn version of tesseract-ocr DO NOT APPLY THE PATCH
