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/


Regards
Marco
