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

["Schmitz, Marco" <marco.schmitz@adesso-mobile.de>]

Okay, my shell script problem "not finding makebox" was a line ending problem (CR+LF).

But how about TESSDATA_PREFIX ?

Hi Marco,

without setting TESSDATA_PREFIX (neither Windows environment variables nor .bash_profile) I get:

$ tesseract --list-langs
Error opening data file C:\DEV\tesseract\Tesseract-OCR\tessdata/eng.traineddata
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.


This is my first problem, which I solved defining TESSDATA_PREFIX (in Windows environment). Now I get:

$ tesseract --list-langs
List of available languages (13):
arbeitsunfaehigkeit
deu
deu_frak
eng
fra
ita
ita_old
nld
osd
por
spa
spa_old
vie


Then I try this:

$ tesseract arbeitsunfaehigkeit.hausarzt.exp0.jpg arbeitsunfaehigkeit batch.nochop makebox Tesseract Open Source OCR Engine v3.04.00 with Leptonica


Okay, but originally I wrote this issue because I tried to call it from a shell script. So, this is my box.sh:

#!/usr/bin/env bash
tesseract arbeitsunfaehigkeit.hausarzt.exp0.jpg arbeitsunfaehigkeit batch.nochop makebox

and calling it brings up the original error:

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


Best regards,
Marco

Are you defining TESSDATA_PREFIX ? Why ?

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/

Marco
