Re: Tesseract 3.04 - Cygwin64 - Windows 8.1 - Can't open makebox

I am using Windows 8.1 and Cygwin64 in order to run Tesseract 3.04.

Running the following command:

     tesseract arbeitsunfaehigkeit.hausarzt.exp0.jpg arbeitsunfaehigkeit batch.nochop makebox

results in the following output:

     Tesseract Open Source OCR Engine v3.04.00 with Leptonica
     read_params_file: Can't open makebox

And this is after I fixed the output:

     Tesseract Open Source OCR Engine v3.04.00 with Leptonica
     Error opening data file C:\DEV\tesseract\Tesseract-OCR\tessdata/eng.traineddata

Are you defining TESSDATA_PREFIX ? Why ?

     Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory.
     Failed loading language 'eng'
     Tesseract couldn't load any languages!
     Could not initialize tesseract.

Using the following line in .bash_profile:

     export TESSDATA_PREFIX="/cygdrive/c/DEV/cygwin64/usr/share/tessdata/"


The default should be

TESSDATA_PREFIX="/usr/share/tessdata/"

Without defining TESSDATA_PREFIX, I have

$ tesseract.exe --list-langs
List of available languages (4):
deu
deu_frak
eng
osd

and the language files are in :

$ ls /usr/share/tessdata/
configs/ eng.cube.fold eng.cube.size osd.traineddata
deu.traineddata       eng.cube.lm      eng.cube.word-freq     pdf.ttf
deu_frak.traineddata  eng.cube.nn      eng.tesseract_cube.nn  tessconfigs/
eng.cube.bigrams      eng.cube.params  eng.traineddata        training/
