Tesseract running error

Question

I have a problem with running tesseract-ocr engine on linux. I've downloaded RUS language data and put it to tessdata directory (/usr/local/share/tessdata). When I'm trying to run tesseract with command tesseract blob.jpg out -l rus , it displays an error:

Error opening data file /usr/local/share/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. 

According to compiling guide, I used export TESSDATA_PREFIX='/usr/local/share/' to point my tessdata directory. Maybe I should edit any config files? Tesseract try to load 'eng' data files instead of 'rus'.

You can grab eng.traineddata Github:

wget https://github.com/tesseract-ocr/tessdata/raw/master/eng.traineddata 

Check https://github.com/tesseract-ocr/tessdata for a full list of trained language data.

When you grab the file(s), move them to the /usr/local/share/tessdata folder. Warning: some Linux distributions (such as openSUSE and Ubuntu) may be expecting it in /usr/share/tessdata instead.

# If you got the data from Google, unzip it first! gunzip eng.traineddata.gz  # Move the data sudo mv -v eng.traineddata /usr/local/share/tessdata/
